This thesis deeply researches the J2EE security strategy on the application tier of enterprise system. The security strategy predigests the information security model and meets the security requirements expediently. But there are some disadvantages when the security requirements become more complex. The expositive security on the Web-Tier can not offer more information for authentication; there is no authentication for EJB-Tier to use, make the EJB-Tier depend on the Web-Tier; J2EE uses database or application server to manage the role information. Use database to manage the role information will increase the complex of enterprise application, and the way of application server will reduce the ability of migrate other J2EE platform. To solve these problems, the thesis designs an improved security strategy model.

本文从企业级系统应用层安全的角度出发，深入研究J2EE多层体系结构的安全策略模型。J2EE提供的安全策略简化了系统的信息安全模型，能够很方便地满足基于J2EE的分布式应用系统的安全需求，但是在面对更加复杂的安全需求时，J2EE安全策略在验证授权和角色管理中还存在不足之处：其在Web层的声明式验证机制无法为用户提供更多验证信息，可扩展性较差；在EJB层缺少业务逻辑层可供采用的验证机制，而是借助于Web层的验证机制，其耦合程度较高有悖于业务逻辑分离于表现逻辑的原则；在角色管理方面，J2EE采用数据库或者应用服务器来管理角色信息，其中，数据库管理角色的方式增加了应用开发的复杂度，应用服务器管理角色降低了系统的可移植性，两者都具有片面性。

The remote measure and control system based on Internet, adopting embedded system platform, accessing the Internet by lineate or radio method, will not only save the cost of invest and maintenance, so as to ensure the flexibility, real-time characteristic and reliability of data and control information, but also enhance the expansibility, transplantability of the system.

此基于互联网的远程测控通信系统，应用嵌入式系统平台采用有线与无线方式可选的接入互联网方案，不仅节省了远程监控网络的投资费用、维护成本，保证了数据和控制信息传输的灵活性、实时性、可靠性，还增加了系统的功能可扩展性、可移植性。

In order to meet the needs of combining the total database system and the future development of system. The system should have the abilities of extensibility, maintainability and good transplantability. Using the model based on distributed multilayer structure can solve the problem above efficiently.

同时，为了满足与工程总数据库系统的衔接及系统将来发展的需要，工程勘测管理信息系统应当具有可扩充的能力和可维护的能力，以及应当具有很好的可移植性，而采用分布式多层结构模型正好可以有效地解决上述问题。

This article?introduces The Fuling?Information System s present situation,analyzes the question existing in the practical application,and makes the corresponding improvement;Moreover,to a new?system,the transplantability is very imp.
