    In object-oriented software development, it is generally accepted that inheritance should be used just to model a generalization/specialization relationship (i.e. an IS-A relation). This analysis/design guideline is too permissive. Some researchers thus advocate that a subclass should inherit the full a behavior of its superclass. Behavior inheritance, however, is far too restricted. In this paper... View full abstract»

    Although many CASE tools for object-oriented methods (OO-CASE tools) have been proposed, few, if any, can verify that the constructed analysis and design models actually match the requirements of the system being developed. In order to realize this kind of verification, we propose a software development method amalgamating OO-CASE tools and algebraic specification techniques. We are developing an ...

    Static program analyzers (SPA) are interactive tools that enhance program understanding by answering queries about programs. An SPA extracts relevant information from input programs and stores it in a program knowledge base (PKB). In this paper, we present a hybrid PKB design model that integrates a relational database with attributed syntax trees. In the hybrid PKB, global properties of programs ... View full abstract»

    Most current software metrics tend to be descriptive with weak prescriptive power; they are not rigid enough to support a successful engineering task as hardware metrics do. We propose the concept of software prescriptive metrics, which set up specific goals to achieve, and thus facilitate, quality control tasks. A general derivation procedure has been developed and applied to derive prescriptive ... View full abstract»

    Concurrent programs are more difficult to test than sequential programs because of nondeterministic behavior. An execution of a concurrent program nondeterministically exercises a sequence of synchronization events, called a synchronization sequence (or SYN-sequence). Nondeterministic testing of a concurrent program P is to execute P with a given input many times in order to exercise distinct SYN-... View full abstract»

    Most electronics products have an embedded MICOM (MIcro COMputer) in which a control program runs. These programs, called microprograms, have usually been developed by electronics engineers in an ad hoc way. Severe competition among electronics companies, however, has forced them to adopt a systematic, engineering method. A model-based software engineering approach is developed in this paper to im...
