將設(shè)計模式引入網(wǎng)管系統(tǒng)可以減少管理系統(tǒng)設(shè)計的復雜度，提高系統(tǒng)的開發(fā)效率。在分析設(shè)計模式中的Singleton模式、Adapter模式、Observer模式的基礎(chǔ)上，討論了體系結(jié)構(gòu)，以及為設(shè)計模式如何實現(xiàn)網(wǎng)管系統(tǒng)功能做出了理論指導。通過分析證明在網(wǎng)管系統(tǒng)中運用設(shè)計模式是提高系統(tǒng)質(zhì)量的有效途徑。

Abstract The using of design patterns in EMS system can decrease the complexity and improve the efficiency of system development. By analyzing Singleton pattern, Adapter pattern, Observer patter, the paper discussed their architectures in detail. In advanced, it can provide a theoretical guide to realize system functions with these patterns. In the end, it analyzed why and how to use these patterns to EMS system. The application of design pattern in EMS has been proved to be an efficient way to enhance the quality of EMS.
