Based On Reusable Software Component Of Software Development Technology

With the increasing needs for software and the ever expanding scale and increasing complexity of software, the traditional pattern for software development is facing a challenge it has never encountered before, so people are searching for new software development technology to meet the needs for software development. One of the effective ways to overcome this "software crisis" is software reuse, in which software component technology plays an important role.The software development technology based on reusable components is a solution which can avoid reusable work for software development. It is the usage of software reuse in practice. It supports the assemble software development pattern. It is based on reusable components, the structure of software and the experiment of software development. It is the best way to minimize code, to lighten the work of software maintenance and test, to avoid to errors to software development again, to increase efficiency of software development through the usage of reusable components.In accord to development of software reuse technology, On the base of analyzing the core of "software crisis" and relevant concepts like software reuse, software component technology, software development methods, this thesis deeply research software development technology based on reusable components.1. This thesis is detail about the definition, classify and the problem of software reuse.2. This thesis is detail about several bascal solutions of software development in order to software development based on reusable components.3. This thesis is detail about the definition of component etc. /It also analyses the management of reusable component.4. The article puts forward the fundamental idea and the lifecycle model of software development based on reusable components. It develops the designing principle of reusable components and components integration software system etc. It starts its work from the two aspects of developing reusable components and application software system based on reusable components.Finally, in giving corresponding developing model and examples, the thesis discusses the application of software development technology based on reusable components in MIS, to make good use of this technology in practice, and test that this technology has great advantage and life-force for software design rapidly.
