课程名称：数据库系统设置：PostgreSQL、MySQL、MS SQL Server 课程概述：数据库系统，或称数据库管理系统（DBMS），是一种用于收集电子和数字记录的软件，能够提取有用信息并存储这些信息。标准数据库的目的是存储和检索数据。标准关系数据库专门设计用于存储和处理结构化数据，通常采用表格形式组织数据，并使用结构化查询语言（SQL）从这些表中访问数据。数据库和数据库系统在处理复杂、快速及多样化的数据集方面起着重要作用。在没有数据库管理系统的情况下，企业将无法获得有价值的洞察和深度分析。 在数据库环境中，数据被访问、修改、控制，并以有序的形式呈现，从而使企业能够执行多种数据处理操作。数据通常以行和列的形式组织，以减少工作负担并快速获得准确结果。数据库管理系统中可存储、处理或检索的数据类型包括数值、时间序列、文本和二进制数据。 PostgreSQL是一种强大的开源对象关系数据库系统，使用并扩展SQL语言，并结合许多特性安全地存储和扩展最复杂的数据工作负载。MySQL是一个开源关系数据库管理系统，用于管理数据库和服务器，广泛用于组织和管理数据库中的数据。微软SQL Server是由微软开发的关系数据库管理系统，主要功能是根据其他软件应用的请求存储和检索数据，这些软件可能运行在同一台计算机上或通过网络在另一台计算机上运行。 该课程将帮助学员掌握数据库系统的基础知识，了解如何设置和管理PostgreSQL、MySQL及MS SQL Server，以应对现代数据处理的需求。
Database Systems or DBMS is software that caters to the collection of electronic and digital records to extract useful information and store that information is known as Database Systems/ Database Management Systems or DBMS. The purpose of a standard database is to store and retrieve data. Databases, such as Standard Relational Databases, are specifically designed to store and process structured data.Generally, Databases have a table to store data, they use Structured Query Language (SQL) to access the data from these tables. Databases and Database Systems play a vital role in processing hard, fast and diverse datasets. Without a Database Management System, businesses won't receive valuable insights and deep analytics.In the Database environment, data is accessed, modified, controlled, and then presented into a well-organized form, allowing the business corporations to execute multiple data-processing operations. The data is usually organized in the form of rows and columns to minimize the workload pressure and achieve accurate results instantly.Different types of data that can be stored, processed, or retrieved in Database Management System include numerical, time series, textual and binary data.PostgreSQL is a powerful, open source object-relational database system that uses and extends the SQL language combined with many features that safely store and scale the most complicated data workloads.MySQL is an open-source relational database management system. MySQL is a tool used to manage databases and servers, so while it's not a database, it's widely used in relation to managing and organising data in databases.Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications-which may run either on the same computer or on another computer across a network.
