面向关系模式——一种全新的数据库框架

摘要：

In order to organize and transform data relations dynamically according to the daily requirements ,a new data model,Relation Oriented model(RO model)is proposed. RO model is described at the physical,data,relational and external schema. In physical schema,a middleware mechanism is used to realize the distributed processing. In data schema ,data group(DG)is defined as the independent atomic unit of data organizing. In relational schema ,the data relations can be organized and transformed dynamically,even on runtime environment. In external schema ,RO model supports the workflow. The building of RO model will reduce the overhead in repeating developments of database applications to a large extent.
