摘  要

现代经济快节奏发展以及不断完善升级的信息化技术，让传统数据信息的管理升级为软件存储，归纳，集中处理数据信息的管理方式。本营业厅宽带系统就是在这样的大环境下诞生，其可以帮助管理者在短时间内处理完毕庞大的数据信息，使用这种软件工具可以帮助管理人员提高事务处理效率，达到事半功倍的效果。此营业厅宽带系统利用当下成熟完善的SSM框架，使用跨平台的可开发大型商业网站的Java语言，以及最受欢迎的RDBMS应用软件之一的Mysql数据库进行程序开发。实现了健身房基础数据的管理，员工的管理，公告信息的发布等功能。营业厅宽带系统的开发根据操作人员需要设计的界面简洁美观，在功能模块布局上跟同类型网站保持一致，程序在实现基本要求功能时，也为数据信息面临的安全问题提供了一些实用的解决方案。可以说该程序在帮助管理者高效率地处理工作事务的同时，也实现了数据信息的整体化，规范化与自动化。
