基于类库组件的EAServer三层结构体系的研究和实现

Research and Application of EAServer Three Tier Architecture Based on Class Libraries and Components

对于大规模的软件系统,简单地组合PowerBuilder和EAServer来进行三层结构业务开发是非常困难的,而且将来维护也是非常艰难的。研究基于类库组件的EAServer三层体系模式,并运用到湖北省电力公司输变电生产管理系统的开发实践,实践证明:该方法增强了软件开发的复用效率,降低开发成本,加快软件的开发进度,降低了软件的维护,提高了系统的稳定性和安全性。

It is difficult to build a large-scale software system based on simple combination of PowerBuilder with EAServer. Research the model of three tier architecture of enterprise application server based on class libraries and components, apply in the produce management information system of transportation and transformer of Hubei province power company. It is proved that the method can enhance system stability and security, save cost, speed up develop, reduce maintenance, increase the software reuse.
