Informatics Economy - Introduction … or why do we deal with diploma/thesis writing in the name of Informatics Economy?!?!?

Disciplines Computer technology: automated data- processing tools and their use in various areas (HW, SW) Information technology: information capture, manage, organize, transmission (see also IT, ICT) The same concept or part-whole relationship?

Disciplines Computer science – "technical informatics" means all the sum of technically possible Informatics – "information economy": within IT the utility (e.g. for an organisation, for a company) is in the central point, or information, such as resource management (cf. information industry, information management)

Disciplines  Information theory: The quantification of information – Genesis, transmission, storage, access (connection: applied mathematics, electrical engineering)  Decision-theory: the decision making process, the necessary information, the alternatives and the choice between them, in the decision-making process in communication (interaction: game theory)  Information science: the appearance of forms of human knowledge, like: collection, classification, storage, disposal (connecting to: library science)

Information subsystems Communication system (CS) Transaction Processing System (TPS) Office automation system (OAS) Management information Sysytem (MIS) Decision Support System (DSS) Executive information System (EIS or ESS) Group work-system (GW) Leading Levels

Information subsystems CS: the exchange of information between persons and groups. OAS: The effective management of personal and organizational data, calculations, documents (in electronic form). GW: Controlled access for resources, duplicated in the management of resources, tasks, organization, organizing, scheduling, monitoring, case management support for groups.

Information subsystems TPS: Collects and stores information about daily business events for higher level systems. (compare with AVIR) MIS: Transaction data is transferred to "information" for the purposes of inspection, planning, decision- making, and to this end, regular or ad hoc reports. Particularly well defined, structured problems. DSS: Leaving the MIS level, gives support for semi-or non-structured problems. EIS: Provides meaningful aggregated information to policy makers, but it provides an opportunity to view the detail (drill-down). Most of the decisions does are not supported directly (EIS vs. ESS).

On the earlier basis, in the Informatics Economy, as anything is almost solved, we only have to compare objects in an objective way… (if the life was so easy it would be true)

The subject’s self task Problem choose (compare with DSS & EIS): ▫ A comparison of the alternatives (objects) (e.g. which subcontractor/ product shall we select), or ▫ Estimating not known phenomena on the basis of known ones (e.g. price estimation on the basis of known product attributes) Data collection and – structuring (compare with TPS): ▫ Selecting the affecting data ▫ Exploring data sources ▫ Sorting data into a single Data Structure (1NF), ▫ Data correction

The subject’s self task Creating a pivot (compare with MIS): ▫ Creating reports needed for the analysis ▫ Creating inspection reports Data analysis (compare with DSS-EIS): ▫ Preparing the adequate single or multi-stage analysis for the problem ▫ Interpretation of the result Reporting (compare with DSS-EIS): ▫ Drawing up the problem (question – targets - utility) ▫ Description of competing solutions (literature) ▫ Description of the analysis, ▫ Drawing the conclusions and recommendations ▫ This is itself the COCO analysis
