It is shown that making use of a single component library to store all kinds ofcomponents and from which components are searched is very inefficient. We construct multi-librariesto support software reuse and use PVM as development environments to imitate large-scale computer,which is expected to fulfill distributed storage and parallel search of components efficiently andimprove software reuse.展开更多

This paper prasents the design and implementation of a components library system model and its support tool UMLCASE, A set of practical CASE tools is constructed. UMLCASE can use UML to design Use Case Diagram, Class Diagram etc. And it integrates with components library system.

To make large amount of the components collaborate, an information exchanging model is essential. In order to retrieve and search the suitable or usable components more effectively, some techniques should be taken into account. Among these techniques, matching strategies and fuzzy URL semantics are significant for the former help us to find components which could be reused and the other both to broaden the searching areas and use some uncertain information to make the searching more purposive. A brief discuss on an abstract component model (UACModel) is begun, which was proposed to promote the interoperability and information exchange among various reusable component libraries (RCLs), and a framework for component retrieval. Then the emphases are put on some matching strategies, especially incomplete ones that encourage reuse through component customization, and fuzzy URL extensions to be supported and realized.展开更多

This paper discusses a series of technologies related with software reuse and software component technology: component model, which describes component's essential characteristics; component acquisition technology, of which domain engineering is the main approach; component management technology, of which component library is the kernel; application integration and composition technology, of which application engineering is the main approach; software evolution technology, of which software reengineering is the main approach, etc. This paper introduces the software development environment: JadeBird Software Production Line System, which effectively integrates the above-mentioned technologies.展开更多
