摘要
目前,各大高校信息化发展的难题之一是信息资源合理分类与管理,而SQL Server数据库集成性较佳,对信息资源管理具有响应速度快的优势。为此设计基于SQL Server的高校信息资源管理系统,对差异信息资源进行分类查询。系统中SQL Server数据库主要由用户从客户端登录资源存储与查询模块,发起某种信息资源查询指令后,使用基于条件互信息的多标签分类查询算法实现对应资源分类查询,将分类查询结果通过客户端反馈至用户。测试结果表明,当不同数量用户在系统中操作不同信息资源管理程序时,系统负载较小,响应时延较低,使用性能较好,是一种高效的信息资源管理工具。
At present,the reasonable classification and management of information resources are the difficult problems in the information development of universities.As the SQL Server database has perfect integration and quick response to the information resources management,the university information resource management system based on SQL Server is designed,and classification inquiry of the different information resources is carried on.After a user logs the resource storage and query module from the client,and initiates a certain information resource query instruction,a multi⁃label classification query algorithm based on conditional mutual information is used to realize the corresponding resource classification query,and the results of the classified query are fedback to the user through the client.When different number of users operate different information resource management programs in the system,the system load is smaller,the response time delay is lower,and the application performance is better.Therefore,it is an efficient information resource management tool.
