课程名称：《数据库技术 - 数据库构建的SQL基础》 课程概述：在现代商业环境中，数据库在信息管理中发挥着至关重要的作用。随着数据的日益增长，企业需要明确未来所需的数据，从而保持高效管理。为了实现这一目标，每个环境都必须维护一个数据库管理系统（DBMS），以便有效管理其数据库。数据库管理系统是一种计算机化系统，允许用户创建和管理数据库。通过DBMS，用户可以定义、构建、操作和共享数据库，支持多个用户和应用程序的访问。 数据库管理系统相比传统文件处理方式具有诸多优点，包括集中存储数据、通过查询和事务程序进行用户访问，以及将数据文件的结构与访问程序分开存储的能力。此外，课程将进一步探讨关系数据库管理系统（RDBMS），其中数据以二维表格（关系）的形式存在。多种数据库管理技术被用于对数据库进行操作。在本课程中，我们将探索结构化查询语言（SQL），该语言在数据库领域中广泛应用，能够执行各种数据库操作。
In current business world, Database plays a vital role in managing the information of any environment. Day by Day data grows enormously for all the environments. At the same time, it is necessary to decide what are all the data required in the future for the environment. In this regard, it is essential for each and every environment to maintain a Database Management System in order to maintain their own databases. The Database Management System is a computerized system allows the users to create and manage a database. A Database Management System enables the user to define, construct, manipulate and share databases among several users and applications The Database management system has various advantage over traditional file processing approach such as Single repository maintains data, User access through queries, transactions and application programs, structure of data files is stored in the DBMS catalog separately from the access programs. The Database Management System further explored as Relational Database Management System. Here Data is viewed as existing in two dimensional tables known as relations. Various Database Management System technologies are used to perform operations on databases. In our course, Structured Query Language (SQL) will be explored to perform the operations in database as it is more popular in the Database world.
