摘要
基于共享数据库的方案是现在高校进行数据集成普遍采用的模式。但随着全局业务的增多,这种方案不可避免地会遇到共享数据库性能瓶颈的问题。从有效利用业务数据库、降低共享数据库业务压力出发,在研究了已有的改进方案之后,对基于共享数据库方案的框架进行改进,提出了一个同时使用共享数据库模式和中介模式,能够进行负载均衡的新的数据集成框架模型。对模型的优劣性进行了分析。
Method based on shared database is wildly used in data integration of campus. This method will encounter capability bottleneck inevitably while the globe business increasing. Aiming pressure release of shared database by using business database effectively, a new data integration framework model is introduced after studying of current improving methods. The model is developing upon shared database model. It uses shared database model and mediator model simultaneously by balancing of the load. After that, analysis of the new model is made.
