| 摘 要： | 在业务逻辑层和关系数据库的物理存储结构中间增加一个O R代理层,提出了一个对象关系数据库系统的三层模型,并对系统模型的各个层次进行了详细的功能设计和分析;总结出了代理层O R映射的4条基本规则,并对各自的优缺点进行了比较.结果表明,该模型在实际应用中存在有效性.

| Abstract: | A threelayers system architecture of orientedobject relative data base is put forward,in which an OR agent layer is added between the operationlayer and the relational database.Each layer and its functions are discussed in detail.Four basic OR mapping rules are presented and described,the advantages and disadvantages are compared respectively.Finally,the validity of the model is demonstrated by practical experences. |
