摘要

随着科学技术的飞速发展，各行各业都在努力与现代先进技术接轨，通过科技手段提高自身的优势，商品交易当然也不能排除在外，随着商品交易管理的不断成熟，它彻底改变了过去传统的经营管理方式，不仅使商品交易管理难度变低了，还提升了商品交易管理的灵活性。这种个性化的网上商品交易特别注重交互协调经营与管理的相互配合，激发了管理人员的创造性与主动性，对商品交易的管理而言非常有利。

网上书城系统的设计主要是对系统所要实现的功能进行详细考虑，确定所要实现的功能后进行界面的设计，在这中间还要考虑如何可以更好的将功能及页面进行很好的结合，方便用户可以很容易明了的找到自己所需要的信息，还有系统平台后期的可操作性，通过对信息内容的详细了解进行技术的开发。

本设计的基本思想就是采用SSM框架开发网上书城系统，以Java为开发语言，MySQL为数据库，。测试结果表明，该网上书城系统能以一种简便、轻量级的方式实现了管理的基本功能，降低了开发的复杂性，提高了系统的可维护性，具有一定的应用价值。

Abstract

With the rapid development of science and technology, all walks of life are trying to connect with modern advanced technology and improve their own advantages through scientific and technological means. With the continuous maturity of commodity transaction management, it has completely changed the traditional management mode in the past, which not only makes commodity transaction management less difficult, but also improves the flexibility of commodity transaction management. This kind of individualized online commodity transaction pays special attention to the mutual coordination of management and management, which stimulates the creativity and initiative of managers, and is very beneficial to the management of commodity trading.

The design of the online book city system is mainly to consider the functions to be realized in detail, to determine the functions to be realized, and to design the interface. In the middle, we also consider how to better combine the functions and pages, so that users can easily find the information they need.

The basic idea of this design is to use the SSM framework to develop the online book city system, Java as the development language, MySQL as the database,. The test results show that the online book city system can realize the basic function of management in a simple and lightweight way, reduce the complexity of development, improve the maintainability of the system, and have certain application value.

Keywords: Online Book City System; Mysql;Java
