Research And Implement Of Reuse-Based Component

In order to solve gradually catastrophic crisis and meet the increasing complex need of software, software reuse is put forward. With the development of object-orient technology, software reuse makes big progress. In the field of present software technology, reuse technology based component is treated as most successful implement of software reuse, and reuse component is paid attention by most researchers, which may support software reuse technology based on component.In this paper, historic background and present state of software reuse technology is introduced, and software reuse is reviewed, including basic concept (definition, classification and hierarchy), merits, its implement (range, chance recognition and key factors) and significance. The component technology is also explained, i.e., component's basic concept, classification, characteristic and its research contents. Moreover, component base is simple introduced, including its implement, organization and maintenance. How to develop based component is also present.Whether design and development of reuse component is reasonable or not, which is directly related to its reuse degree. If the designs reach perfect condition, information from begin to end will be reused. In this paper some technology are discussed in detail, i.e., the relationship between component and reuse technology, implement component using object-orient, how to design component using object-orient.Depending on the development platform of national project in North-west University, that is the component based 3Ds visualized development platform in the condition of Linux, some technology is explained combined actual project development from every stage in software life cycle, i.e., demand analysis, general outline design, detail design, code implement, component test. Using theoretical design reuse component architecture is discussed; through detailed analysis system hierarchy and function model is gotten, how to design component is illustrated by example. Furthermore, the suggestion is also given during personal manager and require. And how to evaluation component is simple introduced.Conclusion is gotten at last.
