基于Epicentre数据模型的图形数据存取规范及实现

Graph data access specification and implement based on epicenter data model

分析了Epicentre模型中图形数据存储模式及管理方式 ,给出了利用DAE完成图形数据存取的过程 ,确定了查询服务器的数据存取模式 ,规定了客户端与服务器端通信协议 ,设计了服务器端的程序流程 。

Epicentre data model is a kind of objecct\|oriented data model. The paper analyzes the stored model and management manner about graph data in Epicentre, presents graph data access course by DAE. We present server's data access mothod and communication protocols between client and server, and implement server's program and client's application programer interface for the purpose of redevelopment.
