基于Web三层结构的统计管理系统

Statistical Management System Based on Trilayer Web Structure

在分析Web三层结构计算模式的基础上,提出了基于Web的统计管理系统Web＿TJ的方法。采用Java数据库连接技术(JDBC),提高了系统的可移植性;采用连接池(ConnectionPool)技术,增强了系统的并发请求处理能力;采用聚集索引和非聚集索引技术,提高了数据访问的速度;采用基于角色的安全访问控制技术,保证了数据访问的安全性。实践表明,该系统安全、可靠,满足用户的各项要求。

A method to design a statistical management system has been proposed on the basis of trilayer web structure. The JDBC technology improves the replantation, the connection pool technology enhances the concurrent request processing capability, the clustered index and non clustered index technology speeds database accessing, the RBAC technology ensures the safety of dada accessing. The practice shows that the system is safe and reliable, and satisfies all the requirements of user.
