The Application Of Component Technology In Electric Power System

With the increasing needs for software, the ever expanding scale together with increasing complexity of software,the traditional pattern for software development is now facing a challenge never encountered before,thus 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.This paper designs and implements a component-based application system--- Electric power marketing system. The paper emphasizes several key technologies such as component-based transaction,component-based security and component management. In the perspective of technique, the thesis, adopting Unified Modeling Language (UML), extracts systematic sample according to field analysis results and has established static and dynamic model. The system, based on component-based three-tiered architectural model,applying component technology,C/S technology,database technology and Internet/Intranet technology,provides applied oriented software based on component with a quite perfect solution; In the perspective of function,in addition to consummate data processing function,it offers Web function. The Design scheme not only has practicality but also has technical leading.The system, being easy in configuration and maintenance,has good scalability and integration. The system has been running stably and efficiently.
