摘要

随着科学技术的飞速发展，社会的方方面面、各行各业都在努力与现代的先进技术接轨，通过科技手段来提高自身的优势，舞蹈网站当然也不能排除在外。舞蹈网站是以实际运用为开发背景，运用软件工程开发方法，采用Java技术构建的一个管理系统。整个开发过程首先对软件系统进行需求分析，得出系统的主要功能。接着对系统进行总体设计和详细设计。总体设计主要包括系统总体结构设计、系统数据结构设计、系统功能设计和系统安全设计等；详细设计主要包括模块实现的关键代码，系统数据库访问和主要功能模块的具体实现等。最后对系统进行功能测试，并对测试结果进行分析总结，及时改进系统中存在的不足，为以后的系统维护提供了方便，也为今后开发类似系统提供了借鉴和帮助。

本舞蹈网站采用的数据库是Mysql，使用SSM框架开发。在设计过程中，充分保证了系统代码的良好可读性、实用性、易扩展性、通用性、便于后期维护、操作方便以及页面简洁等特点。

关键词：舞蹈网站，SSM框架，Mysql数据库
