Data mining with structure adapting neural networks

From specification through refinement to implementation : a comparative study

Van Coppenhagen, Ingrid H. M. 30 June 2002 (has links)
This dissertation investigates the role of specification, refinement and implementation in the software development cycle. Both the structured and object-oriented paradigms are looked at. Particular emphasis is placed on the role of the refinement process. The requirements for the product (system) are determined, the specifications are drawn up, the product is designed, specified, implemented and tested. The stage between the (formal) specification of the system and the implementation of the system is the refinement stage. The refinement process consists out of data refinement, operation refinement, and operation decomposition. In this dissertation, Z, Object-Z and UML (Unified Modelling Language) are used as specification languages and C, C++, Cobol and Object-Oriented Cobol are used as implementation languages. As an illustration a small system, The ITEM System, is specified in Z and UML and implemented in Object-Oriented Cobol. / Computing / M. Sc. (Information Systems)
