基于C++的小型关系型数据库的设计与实现论文

基于 C++的小型关系型数据库的设计与实现摘 要数据库是按一定结构组织的，各种应用相关的所有数据的集合。它包含了数据库管理系统处理的全部数据。其内容主要分为两个部分：一是物理数据库，记载了所有数据；二是数据字典，描述了不同数据之间的关系和数据组织的结构。数据库技术自产生以来，进展到今日已形成了坚实的理论基础和独特的数据处理技术，并获得了广泛的应用。数据库技术是信息社会的重要基础之一，是计算机科学领域中进展最为迅速的分支。关系型数据库是目前最流行的数据库系统。数据库管理系统已经成为软件产业的重要组成部分，是信息化过程中最重要的技术基础之一。我国要振兴软件产业，就必须进展自己的数据库软件产业。本系统运用计算机程序来实现关系型数据库的数据管理，建立一个模拟的关系型数据库，并能够解析 SQL 语句，并执行相应的数据操作。关键词： 关系型数据库；数据库技术；系统设计Based on the C + + A Small Relational Database Design and ImplementationAbstract Database is organized according to certain structure, a collection of all data related to all kinds of application.It contains a database management system to deal with all the data.The main content is divided into two parts: one is the physical database, all data recorded;Second, data dictionary, describes the relationship between the different data and data structure of the organization.Database technology since the produce, development to this day it has formed a solid theoretical foundation and the unique data processing technology, and access to a wide range of applications.Database technology is one of the important basis of information society, is the most rapid development in the area of computer science.A relational database is by far the most popular database system.Database management system has become an important part of the software industry, is one of the most important technology in the process of informatization.To the revitalization of software industry in our c...
