引言
随着社会经济的发展，信息化程度的不断深入，小区的水电费管理工作己愈来愈不能满足用户的需要。现今，人们的金融意识、科技意识己经有了很大的提高，在紧张忙碌的生活中，希望能尽快交费和查询；同时，各种经营单位如电信、移动、供电、煤气、自来水、证券等等一是为了提高服务质量、方便客户，二也是为了希望减轻自己日趋繁重的工作量，都在开发自己的管理系统。如何利用计算机技术加强用户信息管理、进行业务再造，提高工作效率和业务竟争能力是摆在各面向用户服务面前的一个迫切需要解诀的问题。如何利用电子化的手段构建一个高效统一的、通用灵活的系统来管理各种各样的业务，是每个管理者所要研究的课题。
1.1系统开发的意义
随着社会的不断进步和科学技术的增强，二十一世纪的计算机技术将飞速发展，信息化已成为当今世界的发展潮流，计算机代替人工劳动将成为必然，人类追求更简便的工作方式，因此计算机的应用则更加重要。现今，我国的计算机技术高速发展，针对不同的方面，已经有一些软件应运而生，虽然针对企业内部的管理系统也有许多，但也有其相应的优点、缺点。本客户访问信息管理系统是针对对计算机技术不太熟悉的用户而开发的，上手简单，可操作性强。
信息管理系统（Management Information Systems，简称MIS）在现代社会已深入到各行各业，MIS是一个不断发展的新科学，MIS的定义随着计算机技术和通信技术的进步也在不断更新，现阶段普遍认为MIS是由人和计算机设备或其他信息处理手段组成并用于管理信息的系统。MIS的对象是信息。信息是经过加工的数据，信息是对决策者有价值的数据。信息的主要特点是来源分散，数量庞大。因此，MIS是不可缺少的。
管理信息系统（MIS）的概念是1961年美国人J.D.GALLAGHER首先提出来的，是一门新兴的、集管理科学、信息科学、系统科学及计算机科学为一体的综合性学科，研究的是企业中信息管理活动的全过程，以便有效的管理信息，提供各类管理决策信息，辅助企业进行现代化管理。
目前，公司、企业和机关的计算机化管理已经逐渐普及了，计算机技术已经深入到企业的管理的各个方面，因此企业信息化建设也要赶上时代的步伐。目的是为了减轻事务处理人员的劳动强度，辅助企业管理，辅助高层领导决策，提高企业的工作效率，从而使企业能够以少的投入获得更好的社会效益与经济效益。
1.2系统开发的理由
随着计算机技术的迅速发展，企业计算机技术使用的兴起，管理工作也经历了由原始手工操作方式到计算机查询、管理的自动化管理方式的转变。愈来愈多的企业逐渐意识到管理技术的重要性、必要性，并逐步引进稳定性好、安全机制高、方便管理的管理系统。客户信息管理就是其中的一部分。所以运用计算机的自动化管理，将是以后的发展方向。

Introduction
With the social and economic development, information-based level has deepened electricity and water management district has become increasingly unable to meet user''s needs. Nowadays, people''s financial awareness, science and technology awareness has been greatly improved, in the hectic life, hope Contributions and inquiries as soon as possible; the same time, various business units such as telecommunications, mobile, electricity, gas, water , securities, etc. One is to improve service quality, user-friendly, 2 but also to want to reduce the increasingly heavy workload of their own, are to develop their own management systems. How to use computer technology to enhance the user information management, carry out business re-engineering to improve efficiency and operational capacity of competition arising therefrom is placed in front of the user-oriented services, the urgent need for a solution of tactics problems. How to use electronic means to build an efficient unified, universal and flexible system to manage a variety of business, every manager you want to study.
1.1 The significance of system development
Along with social progress and science and technology enhancements, the twenty-first century, the rapid development of computer technology, information technology has become the development trend in today''s world, the computer instead of manual labor will become a necessity, the human pursuit of a more convenient way of working, so the application of computers is even more important. Today, China''s rapid development of computer technology for different aspects, there are already some software came into being, although the internal management system for enterprise, there are many, but also has its corresponding advantages and disadvantages.
