Component Technology Research On The Teaching Courseware Development & Management System

Software reuse has been used to be regarded as an important means to improve the software engineering; it is hoped through the use of the previous code or components to improve production efficiency and quality. As an effective approach to solve software crisis, software reuse is getting more and more attention. With the emergence of the Object-Oriented technology and software component technology ,the software reuse technology develops rapidly .In the paper, we summarize the characteristics of the software reuse technology, expatiate component technology in definition, model , description language, and put forward the developing process of reusable component. Then on the basis of domain knowledge, we discussed how to get the models of specific domain, components are developed and designed based on the domain models. target of Domain-Engineering is to fulfill software reuse in a special domain. Among many methods and tools of Object-Oriented analysis design, Unified Modeling Language absorbs the soul of those and is to describe and construct software system. This paper introduced the basic concept: of UML and the method of component analysis based on UML is presented specifically. At one time, the paper integrates the software reuse thought with the component technology. The components of TCDMS are abstracted...
