A Research On Software Component Acquirement Technology

Software component technology is the kernel in software reuse technology. While, component acquirement technology is the most basic and important in component technology. The paper is set focus on the research of the component acquirement technology.This paper presents two approaches to component acquirement. Aimed at one approach, some matters related CBSD are studied and a software frame structure and a component model are presented. Then the other approach to component acquirement from software systems at present is analysed. And an Object-Oriented component identification arithmetic is given. The arithmetic-optimized proposals are given after analyzing arithmetic and an example is studied. Besides, component adaptability while modified is discussed. Then aimed at the difficultes of component quality evaluation, eight component quality evaluation indexes are presented. In the end, a component reusability metrics model is given. An analyzing method is proposed so that component reusability degree can be measured quantificationally.At the end of this paper, the application of acquirement technology is discussed with the practice of two projects. Acquirement technology study above acts as the foundation of the application and supplies a direction for practice.
