摘要
通过对C/S两层架构和J2EE架构的对比,分析了J2EE架构的特点和应用于电力市场技术支持系统的优势。它能够实现系统各模块间的松散耦合,降低系统开发难度,缩短开发周期,并且不受计算机硬件限制,具备跨平台运行特性。同时分析了J2EE架构运行速度慢、规范不够完善、故障点多和系统成本高等缺点,并针对各应用局限提出了相应的解决方案。
This paper analyzes the characteristics of J2EE application architecture as well as the advantages of its application in power market operation system by comparing it with client-server two-tier application architecture. It can reduce development difficulty and shorten development period by loose coupling among system modules. It is also hardware independent and platform independent. At the same time, after analyzing the disadvantages of J2EE application architecture such as low efficiency, non-perfect specification, more failure points and higher system cost etc. , this paper presents corresponding solutions according to the speciality of each application and the shortcoming of J2EE application architecture.
