基于语义数据库建模的E-R方法研究

数据模型是表示现实世界的一种方法与工具。本文简要介绍了语义模型的一些基本概念,并对E-R模型进行了一些描述,同时提出了E-R建模的一些原理和方法,希望对语义数据库建模的E-R方法进行一些探讨。

Owing to That the Semanteme Data Base Builds Model E-R Method Studies

The data model is one kind of method and implement of the world expressing reality. And the main body of a book brief some basic concept of the model having introduced semanteme, a few having been in progress to E-R model describe that, Have suggested that E-R builds some principle and method of model , the E-R method hoping that the data base builds a model to semanteme carries out a few investigation and discussion at the same time.
