摘 要
客户关系管理是一种旨在改善企业与客户之间关系、提高客户忠诚度的新型运作机制，将企业的市场、销售和服务等有机地整合起来，形成跨部门的统一业务管理平台。
本系统采用三层Web结构，浏览器与服务器进行交互，服务器从后台数据库获取数据。系统前台基于Ajax，利用其核心对象XmlHttpRequest与服务器异步交互，部分交互数据采用XML进行传输，前台浏览器获得XML数据利用DOM文档对象模型进行处理，其中的业务逻辑采用java script语言进行控制，例如：表单数据的提交，表格列表数据的显示，增加，修改，删除等操作。在后台基于ASP.NET平台采用C#语言构服务器，在服务器程序中对通用代码块采用模块化设计思想，将通用代码快设计为类的静态方法，对动态变化的接口参数，采用XML配置文件的方式，动态的从XML文件中读取，避免硬编码带来的重新编译。后台数据库采用稳定，高效SQL Server 2000。数据库设计尽量采用三范式原则，但也同时考虑编程所带来的便利性，必要时采用冗余设计原则。
Ajax在客户管理系统的应用，可以很好的改变系统与客户之间的交互的友好性，网页无刷新重载，提高交互的效率，避免了在网络上发送那些没有改变的信息。

The application of Ajax in client management system
Abstract
Customer relationship management is inter-departmental unified business management platform,which improves relationship between customer and enterpirse and enhance customer loyalty to the new operation mechanism.
The system uses a three-level structure of the Web. The browser interact with server, Server access to data from the background database. System prospects for Ajax, use its core XmlHttpRequest object asynchronous interaction with the server. Some interactive data using XML for transmission, prospects browser access to data using XML DOM document object model, The business logic using java script language for the control, for example : the submission of forms, of table data about adding, modifying, deleting, etc. The background based on ASP.NET platform using C # language structure server, the server process to block generic code modular design concept of universal design for fast code like static methods Dynamic changes in the parameters of the interface, using XML configuration files, from the dynamic XML document read, avoid hard coding the recompiled. Background database using stable, efficient SQL Server 2000. Database design paradigm to maximize the use of three principles, but also consider programming from the convenience, if necessary, redundant design principles.
The application of Ajax in customer management systems, can friendly improve the interaction between system and customer,.The website does not need refreshing and reloading, avoiding the network send the message who do not change.
