1 前言随着计算机技术的发展,数据作为一种重要资源已越来越引起人们的重视。为了妥善地存贮、科学地管理和充分地开发利用这种资源,数据库技术得到了迅速的普及。各行各业都建立了数据库并得到广泛应用。了解数据库的基本知识,掌握数据库的产生,体系结构、物理组成、存取数据库的过程及数据模型的基本概念和原理,了解目前实用的数据库管理系统所采用的数据模型、数据设计规范化基本知识,使之具备在关系型数据库管理系统上开发数据库应用系统的初步能力,已成为煤矿开采现代化对工程技术人员和管理干部的要求,也是当今继续工程教育的内容之一。
1 Introduction With the development of computer technology, data as an important resource has attracted more and more attention. In order to properly store, scientifically manage and fully develop and utilize such resources, the database technology has been rapidly popularized. All walks of life have established a database and has been widely used. Understand the basic knowledge of the database and master the basic concepts and principles of the database generation, architecture, physical composition, access to the database process and data model to understand the data model used in the current practical database management system, basic knowledge of data design standardization, The preliminary ability to develop database application system in relational database management system has become the requirement of engineering technicians and management cadres in the modernization of coal mining and also one of the contents of continuing engineering education.
