数据库系统的建立方法和参考模型

当今计算机技术飞速发展,计算机的应用范围也随之不断扩大。计算机显然已经成为一种被广泛利用的工具,在各行各业中,都可以见到计算机发挥着重要作用。它最常见的工作无非是存储、录入、统计、修改、查询等操作。例如,员工档案管理、学校图书管理、工厂设备管理等,都需要对大批数据进行操作。由此可见,数据库已经成为了现代计算机应用系统和计算机信息系统的核心和基础,也是现代信息技术的不可或缺的组成部分。数据库系统的建立方法的研究和模型的建立,就日益成为计算机应用研究的重要方面。

Methods of Database Creation and Reference Model

With the rapid development of computer technology,the applications of computer also will be expanded.Obviously the computer has become a widely used tool and play an important role in all walks of life.The most common work of the computer is nothing more than storage,logging,statistics,modify,query and so on.For example,the employee records management,the school library management and the devices management of factory,which all have the need for a large number of data operations.Thus,the database has become the core and foundation of a modern computer application systems and computer information systems.It is also an integral part of the modern information technology.Research on database creation and the model of building database are increasingly becoming an important aspect of computer applications.
