推荐答案

SQL简介 [ ^ ]。

大多数数据库系统（例如SQL Server）使用TCP协议在您的计算机上本地运行服务器。当您创建一个与数据库一起使用的应用程序时，您的应用程序将与服务器建立连接并发送命令/查询，服务器将执行数据库操作并返回结果。



还有无服务器数据库（例如SQLite）。这些数据库系统直接读写磁盘文件。在您的应用程序中，SQL查询被解释（您不会自己编写解释代码，但使用现有的库），并且只是在SQL查询指示的情况下将信息写入或从这些文件中获取。

Most database systems (for example SQL Server) locally run a server on your computer, employing the TCP protocol. When you create an application that works with a database, your application will establish a connection with the server and send commands/queries, and the server will perform the database operations and return the results.

There are also serverless databases (for example SQLite). These database systems read and write directly to disk files. In your applications, SQL queries are interpreted (and you would not write the interpretation code yourself, but use an already existing library) and information is just written to, or fetched from, these files as the SQL queries instructed.
