说明：  随着机务段信息化建设的不断深入以及机务安全管理系统的全面实施，越来越多的机务段对网络考试提出了迫切需求。为满足机务段的需求，我们以工程化的软件开发模式，以UML为建模语言，使用ModelMaker这个CASE工具，分析、设计开发成功了一个基于COM+和XML的分布式的多层混合模型的网络考试系统，并提供了与指纹管理系统的接口，推广到库尔勒机务段使用后，反映良好。本文将详细向您介绍网络考试系统的原型及实现方法。
(With the construction of locomotive depot of information, as well as the deepening of Locomotive full implementation of safety management systems, more and more of the locomotive depot of the urgent need for network examination made. In order to meet the needs of Locomotive Depot, we are an engineering-oriented software development models to UML as a modeling language, use the ModelMaker the CASE tool, analysis, design and development of a successful COM+ and XML-based distributed network of multi-layer hybrid model examination system, and provides the interface with the fingerprint management system, extended to Korla Locomotive Depot after use, was well received. This article will introduce you to detail a prototype network test system and the realization method.)
