基于Internet/Intranet的C/S系统集成
|
摘要
对于企业系统的安全及经济运行，基于Internet／Intranet的系统集成是十分重要的研究课题。对去已经提出了许多方法来解决这一应用，但随着计算机技术的不断发展，老的方案已不再适合和应付海量的数据和层出不穷的安全问题。虽然现在几乎所有的开发工具、数据库公司和Internet工具商都提供了对分布式计算的支持，但Web技术应用到企业系统的时间并不长。
在本课题研究中，作者结合对电力系统信息管理系统的实际开发，分析了新的技术方法和计算模式，从而详细的论述综合了“表达”、“业务规范”、“数据服务”为一体的系统集成理论。
论文介绍了分布式应用在企业对象中应用的理论基础，包括三层结构模式及其扩展方法、选择策略、安全策略。进一步的讨论使用MIDAS技术创建三级和多级数据库应用程序,MIDAS是Multi-tier Distributed Application Services Suite(多层分布式应用程序服务包)的缩写，这一新技术使得构建应用服务器更为方便和健壮。本文着重分析了基于中间件的应用服务器在改善系统性能方面的作用，同时也用C++builder具体构建了具有良好性能的应用服务器。其次，局域网的构建方案也是系统集成理论中的重要组成部分，讨论了网络协议的正确选择和使用，及其对系统的整体影响。在另一个层面上，文章论述了以Oracle为代表的面向对象数据库在Internet系统集成上的应用，通过学习电力系统的收费方式、用电营业系统的工作流程及对原有用电营业系统数据库的分析研究，提出了更好的改善方案。针对企业的实际情况，还进一步的扩展了应用程序的功能，如基于Web的查询和决策支持等。从而提高企业部门的工作效率，降低了工作强度。
综合的来说，系统集成既能充分地利用过去的成果，又能及时地采用最先进的科学技术，而且具有开放性、高可靠性以及节省投资、缩短开发周期、避免重复等优点。在这里，系统集成并不只是已有系统的简单堆集，而是采用先进的集成技术将多厂商、多平台、异构网络、不同操作系统的传统应用系统与特定的软件部件有机地结合在一起，形成一个完备的系统，提高各部件互操作和可重构的能力，并使系统的适应性、拓展性大大增强。
To the security and economical operation of the enterprise system, on the basis of system integration of Internet/Intranet being the very important subject for research. To already proposed solving this application in a lot of methods, but with the constant development of the technology of the computer, Old scheme already unsuitable to deal with data and security issue that emerge in an endless stream of magnanimity. Though almost all the developing instrument, the database company and Internet tool company city offer the support to distributed calculation now, But the time that the technical application of Web reaches about the enterprise system is not long.
While studying in this subject, the author combines the actual development of the openning system about the electricity, Having analysed the new technological method and calculation mode, thus the detailed argumentation has synthesized"expressed"," business standard"," service of the data" as a organic whole system integration theory.
The thesis used the theoretical foundation used distributedly among enterprise's target after introducing, Including the mode of three layers of structure and method of expanding, choosing the tactics, security tactics. The further discussion uses MIDAS technology to establish tertiary and multistage data base application program, MIDAS is a abbreviation of Multi-tier Distributed Application Services Suite (the multilevel distributed application program serves the pack ), New technology this make it use server to be more convenient and more stalwart not to structure. This text has analysed the function in improving systematic function of server of application based on the Middleware one emphatically, Structure the application server with good performance concretly with C++ Builder at the same time . Secondly, the construction scheme of the LAN is the important part in the theory of system integration too, The correct choice and using of the procotol, and the integrated influence to the systematic one. On another aspect, have expounded the fact that represented by ORACLE that faces the application in the system integration of Internet of target's data base in article, By studying the charge of the power system, open systematic workflow and open analysis and research of the data base systematically with
electricity to original useful electricity, Improvement scheme that has proposed better. Direct against the actual conditions of enterprises, the function of the further expansion application program, Inquiry for instance based on WEB and decision support,etc.. Thus improve the working efficiency of enterprise's department, reduce the working intensity.
The ones that synthesized said , system integration can fully utilize the achievement in the past, Can adopt the most advanced science and technology in time again, and have openning, high dependability and makesing the investment, shortens construction cycle, avoids the merit of repeating etc. sparingly. Here, system integration is not only simple heap which has already had the system, Adopt advanced integrated technology large manufacturers, Multi-platform, different traditional application system and specific software part which construct the network, different operating system are conbined together organically, Form a complete system, the ability that improves every part and operates each other and can be constructed again, And make systematic adaptability, expanding nature strengthen greatly .
