The Research Of Component-Based Software Reuse

With the fast development of national economy, MIS has spread in almost industries as a trend. To solve the contradiction between software needs and software exploiting ability, it is a vital approach for software enterprises to develop new software programming techniques and methods that can enhance their competitive abilities.This dissertation studies the software-reuse theory and technique, and analyses its further development. Meanwhile, the dissertation proposes a method to exploit component-based software systems after researching different component criterion and summarizing from traditional software exploiting theories and practice methods, which are efficaciously applicable to the life periods of software systems.This dissertation, based on the Chongqing Major Program of Science and Technology (No: 7220-A-1): Applying demonstration of E-government in Nan'an District, presents the whole programming goal, the software architecture, the component-based structure and MIS model based on system analysis. Furthermore, in order to improve the reusability and adaptability, the paper emphatically studies the 2-D model-based sort frame and identification mechanism of software component and also presents correlative algorithms applying to optimize the component reuse during the practical exploitation.The paper emphatically provides theoretical basis and practical guidance for practical system construct...
