    A new approach to the rule-based systems design and implementation process
    (2004) Nalepa, Grzegorz J.
    The paper discusses selected problems encountered in practical rule-based systems (RBS) design and implementation. To solve them XTT, a new visual knowledge representation is introduced. Then a complete, integrated RBS design, implementation and analysis methodology is presented. This methodology is supported by a visual CASE tool called Mirella.The main goal is to move the design procedure to a more abstract, logical level, where knowledge specification is based on use of abstract rule representation. The design specification is automatically translated into Prolog code, so the designer can focus on logical specification of safety and reliability. On the other hand, system formal aspects are automatically verified on-line during the design, so that its verifiable characteristics are preserved.

    Zastosowanie narzędzi CASE do projektowania baz danych systemów informacji geograficznej
    (Wydawnictwa AGH, 2006) Dębińska, Ewa ; Cichociński, Piotr 
    The base for the effective use of the Geographic Information Systems (GIS) is a correctly constructed database allowing quick and swift browsing of the data. Because of GIS specifies, it is necessary that such a database, apart from descriptive data of the objects, also stores information referring to their location and shape. Then such a database, containing geographical information, that distinguishes it from among another databases, can be named a geodatabase. The introduction of the geodatabase model allowed the application of the methods of designing relational databases, including CASE tools, also for geographic information. Apart from theoretical considerations, the paper presents an example of the data model for the evaluation of real estate, containing the definitions of necessary object classes and their relationships.
