摘要
数据库的应用越来越广泛,数据库建模的方法也在不断完善.利用数据库建模工具可以加快数据库建模的速度,保证设计模型和实施模型的一致性,在软件开发过程中的作用也越来越重要.如何建立有效的数据库模型,加快数据库建立过程,是数据库应用程序实施的关键.文中介绍了数据库建模的主要内容,并应用数据库建模工具说明数据库建模的过程,以及利用数据库建模工具的若干技巧.
With the database application more and more widespread,the database modelling method also unceasingly is consummating. Using the database modelling tool may speed up the database modelling,guarantee the design model and the implementation model uniformity,that is more and more important in the software development. How to establish the effective database model,speed up the database creation process,is the key to database application procedure implementation. The article is organized as follows,introduced the database modelling is introduced,and application database modelling tool explanation database modelling process,as well as certain skills about using database modelling tool.
