摘 要

21世纪以来，随着人们生活水平的不断提高，人们对于私家车的需求也越来越大。然而，很多汽车销售公司的业务和环节仍然采用人工记账的传统方法，这样既会出差错，又很容易导致账目上的混乱，并且查询和统计数据起来也极其不方便，既费浪费时间，又很耗费精力，后果严重时甚至会给公司带来不可估计的损失。如何管理好这些事务，让整个公司在销售管理上协调一致，外部高效率地运转，是当今各公司急需解决的问题。

当今时代，汽车产业逐渐成为国民经济的重要组成部分，在经济社会发展的过程中起着举足轻重的作用。在经济全球化趋势的带动下，国际上汽车产业的竞争也显得越来越激烈。与此同时，我国的汽车产业也面临着巨大的和机遇挑战。因此，采用国际先进的管理思想、现代的管理方式成为产业价值链上企业提升核心竞争力的不可或缺的手段。如何利用计算机管理系统方便快捷的存储信息，如何使客户档案信息、业务流程管理实现电子化，是汽车销售企业需要重点关注的问题。这就要求我们充分发挥电子计算机进行信息交流的互动功能和管理功能，把工作重点放在建立和完善汽车销售企业管理信息系统上来。

汽车销售管理系统的建立和不断完善，为汽车销售服务企业综合竞争力的提升提供了可靠的保障。这使得企业的活力得到了有效的增强，企业的绩效得到了全面突破。这些方面更体现了企业面向未来的前瞻运营管理理念，为公司的可持续发展及优势资源整合奠定了坚实的基础。

汽车销售管理系统的设计与实现，不但能使各系统业务环节内部协调一致，而且操作方便，账目清晰。通过简单的账目查询，公司能在最短的时间内准确获得市场的信息，从而来制定相应的决策。因此，该系统主要根据实际的业务需求，采用B/S模式实现了从多个环节数据的跟踪管理服务，基本上满足了汽车销售管理的业务流程。
