摘要
针对传统权限控制设计的问题,提出了一种基于J2EE的B/S系统的权限控制设计。它通过虚拟扩展数据库系统的外模式和虚拟实现数据库的用户授权模式,在数据库连接JDBC与Web的应用服务之间增加数据过滤层,很好地解决了传统设计的不足,大大地提高了系统的灵活性与可扩展性。
The design of B/S system authority control based on J2EE is put forward to avoid the problems which are aroused by the detect of the traditional ones. With virtually extending the external schema of database system and virtually realizing the authorization schema of database users, and inserting a data filter layer between JDBC and Web application service, the lack of the traditional design is supplied, and the flexibility and extensibility of the system are also greatly improved.
