Paper-based database Advantages Disadvantages Briefly, discuss skills and qualifications generally sought in sector…any questions? (7mins)

3 Lesson Objectives To understand what data is and how it is used (i.e. generate information) To understand what information is To be able to identify and discuss what a database is and its purposes (i.e. store data, manipulate and generate information) To identify the advantages and disadvantages of paper-based and computerised databases


5 What is data? Linda: 23011999, 14, 34 Andrew: 05082001, 13, 33
Data is words, dates, numbers or images collected about a location or object. What kind of data do you think the numbers below represent? Linda: , 14, 34 Andrew: , 13, 33 Cynthia: , 15, 38 Name, Date of birth, Age, Shoe size

6 What is information? Information is data that has been processed to be useful and meaningful. To change data into information we have to place it in context and provide answers to who, what, where and when questions.

11 What is a database? A database is like a library – it stores pieces of information called a record. It is a collection of data that is structured – so that its contents can be accessed, managed, updated and presented.

12 Questions How many of you have ever kept details of your friends’ or family’s birthdays in a birthday book? How many of you have written your friends’ addresses into an address book? How many of you have a copy of the Yellow Pages at home? What is the difference between computerised and paper-based databases

13 Can you think of examples of paper-based databases?
These examples are of paper-based databases. However, when we use the term 'database' we generally think of a computerised database.

14 In pairs, think of some advantages of paper-based databases
Inexpensive to set up Don’t need electricity, so you can record data even if there is a power-cut Don’t need a computer – which is expensive

15 In pairs, think of some disadvantages of paper-based databases
Can be lost or damaged It is not easy to make back-up copies Hard to update or make changes Card systems can get in a muddle if cards not replaced in the correct order Can take a while to search for a particular record

16 Can you think of a few examples of computerised databases?
Here are two examples used by the museum

17 Computerised databases
Museum databases These contain records for every object in the museums’ collections. In order to find the right websites, search engines need a vast computerised database which they search using your entered keywords.

18 Think of some advantages for computerised databases
Can easily make back-up copies Can easily make changes Can easily sort data into order e.g. alphabetically Can search for particular records very quickly Can import or export data to/from other packages

19 Think of some disadvantages of computerised databases
Can be lost or damaged Can be expensive to set up if you have to get a professional to make it If there is a power-cut, you can’t use it (unless of course the battery is charged) You need to have a computer

20 Database case study We can search a database to find the information we are looking for. What kind of information do you think your school database has about you?

21 Research task In a Word document, explain how the following professions and organisations use databases: Doctors Schools Libraries Museums

22 Plenary Let’s play dominoes
Working in pairs You have each been given a card with a question on one half and an answer on the other. Is the answer given true or false? Explain your answer.

23 Homework Take a look at the Museum of London's Collections online database. Select any object and list four different types of information that are recorded about it. © Museum of London The Museum cannot take responsibility for edited content.
