Information System Layer
c. n I p u o r G Kresimir Fertalj a e d University of Zagreb, Croatia I t h g i r y p o C In the paper, the concept of informationbase (IB) is described. The IB is a top . layer of the information system (IS). The IB layer uses information systems c n database and existing application programs to provide a structured set of I p uThe reports and graphs, directly and permanently available to the o user. r informationbase described in the article acts as an intelligent and very agile G a e predefined information manager. At appropriate times, it activates options d I t for report generation, supplies the reports with parameters, stores generated h and manages the authorization g i information into a well-organizedrdatabase y of information retrieval.op C Dragan Kovach SUPER-KING Inc., Croatia

Formally, information is a collection of symbols. Within an IS, information can be presented by a collection of various data purposefully and meaningfully organized into a report or graph. In the database of an IS, one has the data, that is only the raw material for the information. Thus, the meta-base aimed to store the information collections, which is described in this article, is referred as informationbase (IB). One of the IS myths is Just enter a command and you will get the information you need. In reality, to get an information, the user needs:

240 • Informationbase
• to browse through the menus in order to find the option one needs, • to understand the capabilities of the option and to enter the parameters required by that option, which requires some skill and effort, • to execute the option and … • … to wait to get the required information. The IB concept, described in this article, changes that completely, i.e. makes the myth true - the user gets the information directly and instantly. The concept is based on the following thinking: all relevant information concerning the scope covered by the IS should be automatically generated and must always be readily available to the users, instead of being ad hoc produced by individuals. Thus the information as the final product of an IS should really (rather than potentially) be available to the users of the information system.
