【摘要】 Web技术的迅速发展，促进了Internert的普及，也是由于Web的盛行，浏览器成为跨平台交流的基础，成为企业对内、对外信息问题存取的必要工具。基于Web的三层体系结构在现代企业管理信息系统中得到了广泛的应用。 本文论述了C／S二层结构在多数据库、多用户情况下的局限性，而C／S／S三层结构具有支持多线程、可供多用户访问的优点。B／S／S是Web技术与C／S／S三层结构的结合，它具有交互性、服务器连续的可扩展性及无须管理的客户方等优点，成为实现本课题的最佳技术方案。本论文还对本课题使用的JAVA语言和JAVA技术的应用进行了论述，同时对本课题采用的INFORMIX数据库、及其特点和结构进行了详细描述。 本课题实现的内容—传输电路管理是通信企业网络资源管理的一项重要内容，数据准确、调度及时是衡量管理工作优劣的标准。本课题采用Client／Web／Server计算机广域网的三层体系结构，运用Internert技术，使用JAVA语言和INFORMIX数据库，实现了对传输电路调度的过程中申请、批复、派发、反馈全过程的自动化，减少了人工操作的环节，同时提供了方便、快捷的查询手段，提高了工作效率和数据的准确性。 目前，本项目已经在全省13个地市正式投入使用。从使用的效果来看，已经基本达到了预期的目标，使企业的内部管理工作又进了一步。 本文最后对传输电路管理系统具有的功能进行了总结和展望。更多还原

【Abstract】 The rapid developing of the WEB technique promotes the popularity of the internet, due to the WEB’ s wide spreading ,browser becomes the communication link across different platforms, it becomes enterprises’ necessary tool for storage-accessing internal and external information. Three Layer Architecture based on WEB is widely used in modern enterprises’ information administration system.In this paper the limitations of Two Layer Architecture C/S for muti-database and muti-users was discussesed. On the contrary ,the Three Layer Architecture C/S/S has the advantages for supporting muti-threading and is available for muti-users ’ visiting. B/S/S is the combinatiotn of WEB technique and Three Layer Architecture C/S/S, it has many advantages, such as interactive, server’s continuous expanding ability and the end-user’s free administration etc., it is the best technical solution for the realization of this system. In this paper JAVA language and the application of JAVA technique, which is used in this system, were expounded , meantime the INFOXMIX database, which is used in this system, its features and structure is also described in details .The administration of transmission circuit , the realization of this system, is one of important task for communication enterprise’s administration of network resources, accurate data and in time dispatching is the standard to distinguish good or bad for administration work. Three Layer Architecture Client/Web/Server of computer wide area network was adopted in this system, applying internet technique, using JAVA language and INFORMIX database ,the automation during the whole process of transmission circuit dispatching was realized, including application, approval, dispatching feedback, manual operation process was reduced, meantime convenient and rapid inquire method was provided, the work efficiency and data accuracy were increased.Till now , this system has started commercial running in 13 cities and areas in Heilongjiang Province. From the view of actual running ,it achieved the desired results, makes a big progress on enterprise’s internal administration work.A summary and prospect for the provided function of transmission circuit administration system was made of this paper in the end.更多还原
