基于云服务的图书馆数据库资源整合研究

Research on library database resource integration based on cloud services

针对传统的图书馆数据库资源整合方法整合过的数据库请求执行响应时间长的问题,设计一种基于云服务的图书馆数据库资源整合方法。利用云服务将图书馆数据库中的资源整合到统一平台上,根据FHO定理识别图书馆数据库中的资源属性,利用资源属性对数据库中的各项参数进行等级划分,分配数据库资源,并根据待分配的数据库对象类型,采用不同策略分配物理资源,最后将数据库资源分配结果与物理资源分配结果结合,完成图书馆数据库资源的整合。以图书馆数据库的响应时间为证明资源整合效果的实验对象,并将传统的资源整合方法与此次设计的资源整合方法作对比,实验对比结果表明,设计的资源整合方法整合后的图书馆数据库响应时间比传统方法的响应时间短,能够有效减少数据库的响应时间,满足图书馆数据库资源整合需求。

In view of the long response time for request execution of the database integrated by the traditional library database resource integration method,a library database resource integration method based on cloud services is designed.The resources in library database are integrated into a unified platform with cloud services.The resource attributes in library database are identified according to the FHO theorem,and then the resource attributes are used to grade the parameters in database and allocate the database resources.According to the database object types under allocation,the physical resources are allocated with different strategies.Finally,the results of database resource allocation and physical resource allocation are combined to integrate the library database resources.The response time of the library database is taken as the experimental object to prove the effect of resource integration.The traditional method of resource integration is compared with the designed method of resource integration.The experimental results show that the response time of the library database integrated by the designed method is shorter than that of the traditional method,and the designed method can effectively reduce the database response time and meet the needs of library database resource integration.
