管理信息系统数据安全性实现方法研究

数据安全性保护是管理信息系统尤其是金融软件最重要的功能之一，如何提高数据安全性是这类软件长期面临的课题。通过对一个预算管理软件数据安全性的研究与实践，总结出一套数据安全性保护所涉及的用户认证、数据加密、数据校验、用户权限管理等措施的实现方法。这些方法已被应用于几个软件的开发中，并取得了用户的认可。所介绍的只是数据安全性问题的一部分，对于如何恢复被破坏的数据以及如何限制系统管理员的权限等问题，还有待于进一步研究。

Data Security Implementation Methods Research in Management Information Systems

Data security is one of the most important functions of Management Information Systems, especially finance softwares, how to improve data security is an ever lasting subject this type of software faces. By research and practice on the data security of a budget management software, a set of methods to implement data security measures such as user authentication, data encryption, data checking, user capability management, and so on, are summarized. These methods were used in some software development, and won approvals of the clients. The problems and methods introduced are only parts of data security, other problems, such as how to restore destroyed data and how to restrict administrator′s capabilities, need more research work.
