The workspace design is usually treated as a part of the user interface design without paying a lot of attention to a workspace design. Such approach works rather well when small IS, which consists of tens of functions and only few actors, is being designed. However, in such case finding optimal and fast solutions can become problematic when IS workspace is being designed for large scale IS. The purpose of this work is to present a model of computerised workspace functionality specification, using information flows specification. The creation of workspace structure is based on function hierarchy model. After making analysis of computerized workspace design and functions modeling, the function hierarchy modeling technique and process of building computerized workspace should be presented, implemented and verified. Also the CASE tool for function modeling and structure of workspace design is described.

The target of this project was to generate a prototype, which would model the elements of the user interface based on the information flow specification. The system is programmed using MS Visual Basic for Applications, its’ graphical environment is MS Visio 2000 and the elements of GUI for modeling are taken from MS Visio 2000 stencil WUI (wui.vss). The created module allows for easy modeling of graphical user interface elements for the data source, which is selected from the database. The processing stages of the data sources are illustrated using MS Visio 2000 documents’ windows, – one window for each stage. In the database, the elements of GUI are associated with the data source processing stages they are related to, i.e. the ones that they are present in. It means, that when working with the system, after selecting the desired data source and its processing stages one wants to model, the system generates the forms with associated GUI elements. This work was being done in the order of the scientific group of Information systems design, which analyses the design of the Information systems in the wide context of requirements engineering, process and data structures specification. This designed and realized model is going to be a part of a CASE tool meant for designing computerized information systems. Once the CASE tool is finished, it is planned to use it for educational purposes in Kaunas University of Technology in the department of Information systems. It is going to... [to full text]
