3 Lesson 1 Introduction to the course – 3 units, coursework worth 30%. Learning intentionsData, Information and Knowledge.Metadata.Information Rich & Information PoorCategories of Information.
4 IntroductionInformation and knowledge are so important that society can be divided up into two groups.Information rich - you have access to:-.many TV and radio channels.books, newspapers and journals.computers and the World Wide Web.Information poor.tend to not have access to the Web and probably find it difficult to access relevant books and journals.If you are following this course you will probably be information rich.
5 Data and Information The Differences Between Data and Information MetadataCategorisation of InformationCharacteristics Which Affect the Quality of Information
6 Data and InformationData is raw unprocessed facts and figures that have no context or purposeful meaning.Information is processed data that has meaning and a context.Data36.41Binary patterns on a discInformation£36.41 – bill for DVD’sProcessed Data – e.g. display on screen, Icons etc.
7 Quiz questionsUsing an example please explain the difference between data, information and knowledge? (3)Explain the difference between information rich and information poor in terms of education and job opportunities. (4)
8 Knowledge Knowledge is gained from Information. We gain knowledge from information and we use that information to make decisions.Explicit knowledge is rules or process or decisions that can be recorded either on paper or in an information system.Tacit knowledge exists inside the minds of humans and is harder to record. It tends to be created from someone’s experiences, again a set of rules or experiences.
9 Metadata Metadata can be thought of as data that describes data. Examples.a data dictionary.the card index system used by libraries pre computerisation, where each card told you the author, title and where to find the book.data about documents or files stored on the computer. The computer keeps a file on its hard disk where it records information about each and every file on the computer. This includes information such as when the file was created or modified; who created it; the size of the file; the file type it is. This master or directory file is an example of metadata.

11 Categorisation of Information Information can be categorised under several headings that allow us to determine the overall usefulness of it.Main categoriesSource – Primary, Secondary, Internal, ExternalNature – Formal, InformalLevel – Strategic, Tactical, OperationalTime – Historic, Present & Future.Frequency – Continuous, periodicUse – Decision Making, PlanningForm – Written, Aural and VisualType - Detailed, sampled, aggregated.
13 Source – Primary or Secondary A primary source provides the data to an information system from an original source document.E.g an invoice sent to a business or a cheque received.sales figures for a range of goods for a tinned food manufacturer for one week or several weeks and several locations. A secondary source of information is one that provides information from a source other than the original.E.g. an accounts book detailing invoices received, a bank statement that shows details of cheques paid in.Where statistical information is gathered, such as in surveys or polls, the survey data or polling data is the primary source and the conclusions reached from the survey or the results of the poll are secondary sources
14 Source – InternalInternal - All organisations generate a substantial amount of internal information relating to their operation.Examples of Internal sourcesMarketing and sales information on performance, revenues, markets shares, distribution channels etc.Production and operational information on assets, quality, standards etc.Financial information on profits, costs, margins, cash flows, investments etc.Internal documentation such as order forms, invoices, credit notes, procedural manuals.
15 Source – ExternalExternal - An external source of information is concerned with what is happening beyond the boundaries of the organisation.census figuresjudgments on court caseslegislation, for example the Data Protection Acttrade journalsprofessional publicationsindustry standardsTelephone directoriescomputer users’ yearbookgallup & national opinion pollsordinance survey mapsFinancial services agencies such as Dunn and Bradstreetthe Internet
16 Source - Nature Formal Communication Informal Communication information presented in a structured and consistent manner.main methodsthe formal letter, properly structured reports, writing of training materials etc. in cogent, coherent, well-structured language. Informal Communicationless well-structured informationtransmitted within an organization or between individuals usually who know each other.Quantitative Informationinformation that is represented numerically. Qualitative Informationinformation that is represented using words.
17 Levels of InformationLong-term decisions - both internal & external sourcesTop level of managementSTRATEGICTACTICALOPERATIONALMedium-term decisions - mostly internal but some external sourcesMiddle managementDay-to-day decisions - largely internal sourcesLowest level of staff
18 Time Historic Present Future Information gathered and stored over a period of time.It allows decision makers to draw comparison between previous and present activities.Historic information can be used to identify trends over a period of time.PresentInformation created from activities during the current work-window (day, week or month).In real-time systems this information would be created instantly from the data gathered (the temperature in a nuclear power plant turbine) giving accurate and up-to-date information.FutureInformation that is created using present and historic information to try to predict the future activities and events relating to the operation of an organisation.
19 Frequency of Information ContinuousThis is information created from data gathered several times a second. It is the type of information created by a real-time system. PeriodicInformation created at regular time intervals (hourly, daily, monthly, annually).Annually - On an annual basis a company must submit its report and accounts to the shareholders.Monthly – Banks and credit card companies produce monthly statements for the majority of its customers.Daily – A supermarket will make daily summaries of its sales and use the product information to update its stock levels and reorder stock automatically.Hourly – A busy call centre will often update totals for each operator on an hourly basis and give the top employee for the hour some reward.
20 Uses of Information within Organisations Planning is the process of deciding, in advance, what has to be done and how it is to be done.planning means decisions by management about:What is to be done in the futureHow to do itWhen to do itWho is to do itAn objective is something that needs to be achievedA plan contains the activities or actions required to achieve the objective
21 Uses of Information within Organisations Control is the monitoring and evaluation of current progress against the steps of a predefined plan or standard.Operational levelthe manager ‘s time will be spent on control activitiesAt higher levelsplanning and control are more closely linked, with management being concerned with the monitoring of progress against the plan, assessing the suitability of the plan itself and predicting future conditions.
22 Uses of Information within Organisations Decision-making –selecting an action or actions from those possible based on the information available.involves determining and examining the available actions and then selecting the most appropriate actions in order to achieve the required results.an essential part of management and is carried out at all levels of management for all tasks. made up of four phases:· Finding occasions for decision making· Find possible courses of action· Choosing among these courses of action· Evaluating past choices
23 Forms of Information Written. Aural. Visual. hand-written, word-processed, s.reports from different classes of software.reports, memos and tables, receipts, invoices, statements, summary accounting information.Aural.Speech, formal meetings, informal meetings, talking on the phone and voic messages.Employee presentations to a group where there may be use made of music and sound effects as well as speech.Visual.pictures, charts and graphs.Presentations via data projects, DVD’s etc.
24 Types of Information Detailed Sampled Aggregated an inventory list showing stock levelsactual costs to the penny of goodsdetailed operating instructionsmost often used at operational level SampledSelected records from a databaseProduct and sales summaries in a supermarketoften used at a tactical level (maybe strategic) Aggregatedtotals created when detailed information is summed together.details of purchases made by customers totaled each month
25 Characteristics of Information Availability / AccessibilityInformation should be easy to obtain or accessAccuracyInformation needs to be accurate enough for the use it is going to be put.Reliability or ObjectivityReliability deals with the truth of information or the objectivity with which it is presented.Relevance / AppropriatenessInformation should be relevant to the purpose for which it is required. It must be suitable.
26 Characteristics of Information Completeness.Information should contain all details required by the user.Level of Detail / Conciseness.Information should be in a form that is short enough to allow for its examination and use. There should be no extraneous information.Presentation.Information can be more easily assimilated if it is aesthetically pleasing.Timing.Information must be on time for the purpose for which it is required. Information received too late will be irrelevant.
27 Characteristics – Value and Cost The relative importance of information for decision-making can increase or decrease its value to an organisation.Cost.Information should be available within set cost levels that may vary dependent on situation.The Difference Between Value and Cost.Valuable information need not cost much.Information costly to obtain may not have much value.
28 Organisational Information Systems Categories of Information SystemsOrganisational Management SystemsConcepts, functions & strategiesCentralised databaseNetwork StrategySecurity StrategyBackup StrategyUpgrade StrategySoftware StrategyDistributed databases, data warehousing & data mining
29 Categories of Information Systems Data Processing Systems (DPS) - OperationalManagement Information Systems (MIS) - TacticalDecision Support Systems (DSS) - TacticalExecutive Information System (EIS) - Strategic
30 Data Processing Systems Transactional Processing SystemDeals with day to day transactionsAccountancy, Invoicing, Stock ControlItems scanned by bar code readerDPS are the tools used at the Operational level of an organisation.DPS involves use of a computer
31 Management Information Systems MIS converts data from internal and external sources into information for managers.The source of data for a MIS usually comes from numerous databases. These databases are usually the data storage for Data Processing Systems.MIS summarise and report on the organisations basic operations. .MIS produce reports for managers interested in historic trends on a regular basis.MIS operate at the tactical level.
32 Decision Support Systems A DSS provides information and models in a form to help tactical and strategic decision-making.They support management decision-making by integrating:Company performance data;Business rules in a decision table;Analytical tools and models for forecasting and planning;A simple user interface to query the system. .DSS are useful when making ad-hoc, one off decisions.The source of data for a DSS tends to be a combination of summary information gathered from lower level DPS and MIS.
33 Executive Information System An EIS provides senior managers with a system to assist in taking strategic and tactical decisions.purpose - analyse, compare and identify trends to help the strategic direction of the organisation.EIS incorporate data about external events.draw summarised information from internal MIS and DSS.Systems filter, compress, and track critical data.reduce time and effort required to obtain information useful to strategic management.employ advanced graphics software to provide highly visual and easy-to-use representations of complex information and current trends.they do not provide analytical models.EIS allow the user to look at specific data that has been summarised from lower levels within the organisation and then drill down to increase the level of detail - data warehouse analysis.
34 Expert SystemsAn expert system is a computer program that tries to emulate human reasoning. It does this by combining the knowledge of human experts and then, following a set of rules, draws inferences. .An expert system is made up of three parts.a knowledge base stores all of the facts, rules and information needed to represent the knowledge of the expert.an inference engine interprets the rules and facts to find solutions to user queries.a user interface allows new knowledge to be entered and the system queried.Reasons for Expert Systems.To store information in an active form as organisational memory.To create a mechanism that is not subject to human feelings, such as fatigue and worry.To generate solutions to specific problems that are too substantial and complex to be analysed by human beings in a short period of time.
36 Organisational Information System Management Strategies Network Strategy.Addresses Data Transfer, Distribution, Access & Security, Facilities, Storage.Security Strategy.Deals with access to the network and keeping unauthorised people out.Backup & Recovery Strategy.To ensure data is not accidentally erased and can be recovered once backed up.Upgrade Strategy.To plan new hardware and software and ensure everything new will work properly.Software Strategy.Choose between bespoke and standard packages.
37 Centralised DatabaseA very large and powerful database - at the heart of an organisation.Database program is called the database engine and it saves and indexes files in tables and manages the relationships between the tables.information can be found fairly easily by querying the centralised database.Usually a multi-user or network system is used which means that any user on the system can have access to the database.Advantages to the database being centralised.much easier to organise, edit, update and back-up the data.Communications are easier.no real disadvantages to a centralised database.
38 Network Strategy Networks. LAN (Local Area Network) – in one building. Device Sharing.Software Sharing.Data Sharing.Communication.WAN (Wide Area Network) – over a city, country or the wide world.Uses telecommunications.Distributed Networks.LAN with several servers, data accessible from all over the network.
39 Network Hardware Client-Server Network. Central server stores data files and log-in details.Peer to Peer network.No central server, all stations equal.Cheaper, data less secure.workstation
40 Network Hardware Network Adapter Card. Structured Cabling. Built-in to the computer.Allows the computer to send and receive data around the network.Structured Cabling.Cables made from copper wire, co-axial cable, fibre optic cable and twisted pairs.Twisted pair Ethernet most Common.Fibre Optic used to link over longer distances and to carry a very high bandwidth.
41 Network Software Network Operating System. – 2 parts the version that runs on the server.needed to control which users and workstations can access the server,keep each user’s data secure. control the flow of information around the network.It is also responsible for file and data sharing, communications between users and hardware and peripheral sharing.the version that runs on the personal computers to turn them into network stations.Each workstation (computer) connected to the network needs the Network Operating System installed before it can connect successfully to the network facilities.
42 Network Software Network Auditing and Monitoring Software. This software keeps a track of network activity.It records user activity and workstation activity.In a commercial organisation this sort of auditing and monitoring can be used to detect fraud and suspicious activity.
43 Security Strategy Security, Integrity and Privacy of Data. Data Security means keeping data safe from physical loss.Data Integrity means the correctness of the stored data.Data Privacy means keeping data secret so that unauthorised users cannot access it.
44 The Security Risks to Information Systems A viruspiece of programming code that causes some unexpected and usually undesirable event in a computer system.Viruses can be transmittedas attachments to anas a download,on a disk being used for something else.Some viruses take effect as soon as their code takes residence in a systemothers lie dormant until something triggers their code to be executed by the computer.Viruses can be extremely harmful and may erase data or require the reformatting of a hard disk once they have been removed
45 The Security Risks to Information Systems Hackingis gaining unauthorised access to a computer information system.the offence is maliciously altering data or stealing information.Denial of serviceThis involves flooding an organisation’s Internet server with a surprisingly large amount of requests for information (traffic).This increase in traffic overloads the server, which is incapable of dealing with the backlog of requests, results in the server crashing or needing to be taken offline to resolve the problem.
46 Policies and Procedures for Implementing Data Security Codes of conductapply to users of an information system.Most organisations insist that users follow a set of rules for using their system.Employees have to sign a code of conduct as part of their conditions of employment.A code of conduct can cover basic professional competences as well as obvious statements like “Never disclose your password to anybody else and change your password every week.”
47 Policies and Procedures for Implementing Data Security BCS Code of Ethics Covers:-Professional conductProfessional integrityPublic interestFidelityTechnical competencePassword guidelinesMinimum length of 5 charactersMust consist of letters and numbersMust not contain any wordsCannot be the same as the previous passwordCannot use easily guessed strings of letters or numbers (e.g and abcdef)
48 Implementing Data Security Virus Protection.Prevention.Prevent users from using floppy disks.Scan incoming s for viruses.Do not open mail or attachments from someone you don’t recognise.Detection.Install Anti-virus software.Update it regularly to detect new viruses.Repair.Anti-virus s/w can quarantine a virus.Can delete the virus code from an infected file.
49 Implementing Data Security Firewalls.Device or software used to prevent unauthorised access to a network.Placed between the server and the Internet connection (router).Can block sections of the network.Only allows authorised users to join the network (dial-in).Encryption.Used by on-line retailers to keep card details secure.Need it to gain trust of purchasers.32 bit encryption almost impossible to crack.
50 Implementing Data Security Access Rights.Read – allows users to read files.Allows files to be made read only.Write – allows users to write (save) files.Create – allows users to create new files.Erase – allows users to erase files.Modify – allows users to modify files.Groups of users may have.Read/write/create/erase on home drive.Read only on shared areas.
51 Backup StrategyEvery computer user should have a strategy in place to backup their data.Backing up is the process of making a copy of data stored on fixed hard disks to some other media.This can be tape, external portable hard disks, writeable CD-ROM or DVD.The purpose of backing up data is to ensure that the most recent copy of the data can be recovered and restored in the event of data loss.Reasons for loss.electronic disasters such as a disk head.files being accidentally erased,the disk being attacked by a virus.
52 Archive, Recovery and Storage Methods The process of copying data from hard disk drives to tape or other media for long-term storage.Data verification.it is important to check that the data stored on the backup media can be recovered.Storage Methods.DAT tape on built in drives on servers.USB removable hard drives.Frequency and Version Control.Full backup (weekly) and incremental daily.Grandfather, father, son method.
53 Upgrade Strategy Future Proofing. making sure that a system has a reasonable life and does not need to be totally replaced too soon.Hardware & software compatibilitywill older s/w work with new operating systems etc.will older h/w work with newer equipment (e.g. printers with computers).
54 Upgrade Strategy Integration Testing. Are the peripheral devices compatible with the hardware and operating system?Does the network software support the hardware and operating system?Is the application software compatible with the operating system and computer?Is the hardware compatible with the operating system?Legacy Systems.Old information systems running on out of date hardware and operating systems are often referred to as legacy systems.problems with legacy systems lead to many computer companies developing software that conformed to Open Standards.Emulation.allows access to greater range of applications that might not be available on the given hardware platform.The use of an emulator allows data to be transferred between platforms.
55 Software Strategy Needs to take account of the issues :- evaluating the software for use, using several key criteriathe user support for the softwarethe training supplied for end users of the softwarethe upgrade path of the software
56 Software Evaluation Software Evaluation should cover. Functionality - This refers not only to the number of features an application program has but the number of useable features it has. Also the tasks to be completed need to be evaluated against the features in the software.Performance – The performance of software can be measured by several different criteria depending on the type of software.
57 Criteria for Evaluation of Software Reliability.Does the job it is supposed to.Resource Requirements.Has the computer enough RAM, big enough disks etc.Portability.Will it work on different systems.Support.Assistance from vendors or writers.Speed.Measured against benchmarks.Usability.Look and feel, choices in menus etc.Compatibility.With operating system.Data Migration.Translating from one format to another.
58 Training in Using Software On-the-job.A new user needs to be introduced to the software.working through a tutorial to become familiar with the functions of the software.online tutorial program or tutorial manual that teaches the user about the software.In House.This is when small groups of staff, within the company receive a training course delivered by IT staff. External.Offered by specialist training providers for popular application software, such as software created by Microsoft, Macromedia and Adobe.
60 User SupportManuals.Installation Guide – gives advice on how to install the software and how to configure it to work with various hardware.Tutorial Guide – gives step-by-step instructions on how to use the software.Reference Manual – Is an indexed guide detailing all the functions of the software.On-line Help.Explains to the user what each feature of the software does. It is a part of the program situated on the computer and is not on the Internet.On-line Tutorials.Step by step instructions on the computer not on the Internet.
61 Explain the Following Issues Affecting Decisions to Upgrade Software User SupportCriteria for Evaluation of SoftwareTraining in Using SoftwareExplain the 4 Organisational Information Systems
62 User Support Help Desk. Newsgroups. FAQs. Internal (end user) and external (software vendors).Newsgroups.A Newsgroup allows users of a piece of software to post messages to the wider user community.FAQs.This stands for Frequently Asked Questions. It is usually a file that contains a list of commonly asked user queries about a piece of software.
63 Issues Affecting Decisions to Upgrade Software Lack of functionality.Business changes, new technology outdates software.Hardware Incompatibility.Upgraded computers do not support old software.Software Incompatibility.New operating system will not run old software.Perfecting the Software.Removing bugs and improving it – will existing data work with it.
64 Centralised and Distributed Databases Centralised database.All the data is held on a central computer- mainframe or server.Advantages.far easier to manage and control if it is only in one location.far easier to back up when it is centralised.Distributed Database.Consists of two or more files located at different sites on a computer network.different users can access it without interfering with one another.The DBMS must synchronise the scattered databases to make sure they all have consistent data.
65 Data Warehousing Data warehousing. Historical data transactions are separated out from the business.The data is re-organised in such a way as to allow it to be analysed, the newly structured data is then queried and the results of the query are reported.Data warehousing could be used as a predictive tool, to indicate what should be done in the future.The main use of data warehousing is as a review tool, to monitor the effects of previous operational decisions made in the course of a business.
66 Data Mining Data mining. "The nontrivial extraction of implicit, previously unknown, and potentially useful information from data".It uses machine learning, statistical and visualisation techniques to discover and present knowledge in a form, which is easily comprehensible to humans.Data mining is the analysis of data and the use of software techniques for finding patterns and regularities in sets of data. The computer is responsible for finding the patterns by identifying the underlying rules and features in the data.The mining analogy is that large volumes of data are sifted in an attempt to find something worthwhile (in a mining operation large amounts of low grade materials are sifted through in order to find something of value.)
67 Information Management Software Classes of SoftwarePrint Media, On-line Media, Spreadsheet, Project Management, PIMWord processing / DTP softwarePresentation / Web Authoring s/wSpreadsheet softwareProject Management SoftwarePersonal Information Management SoftwareEvaluation of Software
68 Classes of Software There are five classes of software:- Presenting Information for Print mediaPresenting Information for On-Line MediaSpreadsheet (data handling)Project ManagementPersonal Information Management
69 Presenting Information for Print Media Most applications are designed to produce printed output except for graphics and web authoring which tend to be more visual.Only Word Processing (WP) and Desk Top Publishing are classed in this group.Differences between WP and DTP.WP is used for generating text, while DTP tends to use pre-prepared text.DTP manages to handle text and graphics far more easily.WP can deal with multi-page documents but DTP handles multi-page documents far better.DTP files tend to be very large especially if real pictures are used.
70 Presenting Information for On-line Media Presentations.large growth in the use of s/w to create presentations.cost of data projectors has dropped.Presentation s/w allows the user to create a slide show.Slides can hold a variety of multimedia objects,Slides can be sequenced - jump to using hyperlinks.PowerPoint most popular package.Web Authoring.software allows users to easily make up web pages.drag and drop objects onto the screen.Click on icons to link graphics and media files.deal easily with hyper-linking.File written as HTML or XTML code.
71 Data Handling – Spreadsheet Education.record and analyse marks and resultskeeping track of budgets and financial information,Home situation.keep track of household expenditure, track share values and even keep track of contacts.very good at formatting output, used for printing address labels.Financial Application.cash flow forecast, statement of accounts, invoices, sales orders, purchase orders etc.Modelling and Simulation.predicting a new situation from existing one - “what-if? analysis.”Statistical Analysis.E.g. analysis of numerical information. Two examples are Descriptive Statistics and Goal Seeking.Macro Use.A Macro is a sequence of instructions that can be used to automate complex or repetitive tasks.
72 Project Management The software. used to help manage a project. planning, monitoring and control of the various activities or resources that contribute to its success.Project management.identifying the activities that need to be carried out to complete the project.For each activity - duration; cost; resources; employees; inter-relationships - all need to be assigned.Activities scheduled to ensure efficiency.Plan output as PERT or Gantt chart.Software Packages.Microsoft Project; CA SuperProject and Hoskyns Project Managers Workbench.
73 Personal Information Management Personal information management software (PIM)type of software application designed to help users organise random bits of information.PIMs enable you to enter various kinds of textual notesreminders, lists, and dates - and to link these bits of information together in useful ways.Many PIMs also include calendar, scheduling, and calculator programs.
74 Word Processing Software Data Objects.characters, wordsparagraphs, graphic objects.Operations.File Menu – performed on whole files.Edit Menu – cut, copy and paste.View Menu – including headers and footers.Insert Menu – Page break, date/time, picture etc.Format Menu – format text (an extensive menu).Tools Menu – Mail merge, spelling and grammar, options and customisation.Table Menu – Insert table then table operations.Window and Help much as in other Windows applications.Formatting functions are found mostly in the format menu and also on the icons on the menu line with B I U on it.
75 Desk Top Publishing Standard File, Edit, View, Window, Help. Also Layout, Type, Element Utility.most of the formatting functions here.Also a Toolbox.Arrow and Text , basic drawing tools, and a colour palette.
76 Desk Top Publishing Advanced operations and functions Page Layout Headers and FootersColumnsMulti-Page LayoutPaginationContents and IndexingStyle SheetsFont Selection – Serif v San-SerifColour use
77 Desk Top Publishing Inserting Graphics. Formatting Graphics. Clip Art. Scanned pictures.Digital Camera.Formatting Graphics.How graphic behaves on the page.Square, Tight, in front of, behind.A graphic formatted with Tight Layout means text flows around it.
78 Web Authoring Software Page Structure.Individual pages linked to form a site.Incorporation of Graphics.Used to enhance appearance of the page.Graphics should be JPEG or GIF – size matters.Graphics linked to the page (not pasted in).Presentation Style.Font selection limited, careful use of colour.Navigation.Pages linked together by Hyperlinks.Set Home Page, use arrows, bookmarks, history.Templates.Use style sheets to provide common fonts, colours etc.
79 Presentation Software Page Structure.Individual slides follow a linear pattern, can be hyperlinked.Incorporation of Graphics.Used to enhance appearance of the page.Graphics inserted into slide, embedded in the page.Presentation Style.Font selection vast, careful use of colourNavigation.Move to next slide by click of mouse.Slides can be linked together by Hyperlinks.Templates.Various pre-prepared templates available.Can make up own template as a slide master.
80 Spreadsheet Software Data Objects. Operations. Cells and groups of cellscontaining text, numbers, formulas.Operations.File Menu – performed on whole files.Edit Menu – cut, copy and paste.View Menu – including headers and footers.Insert Menu – rows, columns, worksheet, functions.Format Menu – format cells including numeric like currency as well as standard text formatting.Tools Menu – spelling protection and macros.Data Menu – Sort, filter and pivot tables.Window and Help much as in other Windows applications.Formatting functions are found mostly in the format menu and also on the icons on the menu line with B I U on it.
81 Spreadsheet Software Advanced Functions. Goal Seeking. Automatically change values until desired result achieved.Forecasting.Calculates or predicts a future value by using existing values.Look-up Tables.Can be used to insert text in a cell depending on a value.E.g. Grades or Pass/Fail from an exam mark.Nested If.Using an IF function within an If function.Count.Gets the number of entries in a range of cells (COUNTA for text values).Macros.A sequence of instructions that can be used to automate a task.
82 Project Management Timelining. Resource Allocation. Shows how and when a task needs to be completed before the next one starts.Resource Allocation.Software tools to help match up the materials, machine, people and money.Maximising profits or achieve best quality.Gant and PERTT charts.Gant shows timings of each activity in a chart.PERTT shows relationship between activities.Optimisation & Critical Path Analysis.A mathematical process concerned with the optimisation of time.Used for very complicated processes (managing a production line).
83 Personal Information Management (PIM) Such as Microsoft Outlook.Contacts - can be thought of as a very comprehensive address book.Calendar - lets the user keep a diary of events, meetings, appointments and activities.Task List - This is also called a “To-do list”. It keeps a list of all the tasks that require to be carried out and reminds the user when each task is due to be completed.Communication - ; Most PIM applications support sending, receiving and management of s.

91 Adv of Online retailCompany does not need to pay for rent etc of their stores.Shop from homeGreater choice onlineComparisons EasySave on staff costsWider range of customers, sell 24/7
92 Disadv of online retail No face to face contactPay for domain namePay for deliveryTake what you get for foodDon’t see/touch/try on the product
93 Globalisation Increased trade means a wider choice of products Big brands dominate offering the same products worldwide
94 Identities, Personas, Avatars People can hide their true identityAvatar – cartoon picture of a person
95 Personal Privacy Far less private It’s easy to find out information about anyoneSocial Network sites.
96 The Changing Relationships between Retailer and Customer Shoppers are:-.Becoming intolerant of goods being unavailable or out of stock.Very wary of over-pricing and long delivery times.Consumers are:-.More willing to go on-line and order from different retailers.Need a credit card to buy on-line.Stress of waiting for goods bought as presents not turning up.We still maintain relationships:With local specialist shops.Customers who buy their groceries on-line and have the same delivery driver every week often build up a good relationship with the driver.In General.The two types of shopping can complement each other, opening up new markets to specialist retailers and giving more choice to customers.
97 Globalisation Globalisation. The growing integration of economies and societies around the world.Has been hotly debated topic in economics.Positive Aspects of Globalisation.Rapid growth and poverty reduction in China, India, and other countries that were poor 20 years ago.Negative Aspects of Globalisation.It has increased inequality.Contributed to environmental degradation.Confined to huge companies as divers as Oil, Cola. And burgers.
98 Impact of IS on Business and Societies Multinational companies.As diverse as Cola and Oil technology.achieved globalisation through the use of information systems.Originally a few large companies with mainframe computers.Confined to major USA and European cities.Present day examples of Globalisation.Smaller companies have global presence.Communicate via dedicated worldwide intranet.Publish reports, memos etc & e:mail round the world.Don’t need mainframe systems.Use web and mail servers to communicate.
99 The Impact on Business of an IS Driven Business Model Traditional Businesses.Have embraced IT with open arms.Have had IT forced upon them and adapted.Modern IS driven businesses.Companies without High Street branches.Call centre based companies.Advertise heavily on TV.Much cheaper than running a network of branches.Call centres can bring employment to towns rather than cities.
100 Identities & Personas Using the Internet as a medium of communication. Change is having a dramatic impact on people’s lives.Ability to communicate with anyone regardless of age, sex, location, background etc.The Internet allows people to develop different identities and personas when communicating.Can join chat rooms and newsgroups and offer an expert opinion even when not an expert.Disadvantages.Criminal offence of “grooming” via the Internet.Parents wary of letting teenagers have use of the Internet.Fear of the Internet among certain groups in society.Read about.Jonathan Lebed and Marcus Arnold either online or in the notes.
101 Privacy Private Communications across the Internet. Should be secure and safe.Feel we have a right to this privacy.Web sites we visit should be our business.National Security or Criminal Actions.Terrorists use e:mail, mobile phones and the Internet to communicate amongst themselves.Criminals use the Internet to host web sites.What about our privacy?Security organisations can scan all e:mail and mobile phone messages looking for tell tale phrases.FBI caught thousands of paedophiles across USA and Europe via their IP address and phone number.
102 Legal Implications of Information Systems The Data Protection Act 1998Copyright Designs and Patents Act 1988The Regulation of Investigatory Powers Act 2000The Freedom of Information Act (Scotland) 2002Health and safety Regulations
