As a domain expert in database management, I can explain that an SQL database is a type of database that uses the SQL language for accessing and managing data. SQL, which stands for Structured Query Language, is a standard programming language designed for managing data held in a relational database management system (RDBMS). An SQL database is organized into tables, which consist of rows and columns. Each table represents a different type of data structure, with each row being a single record and each column representing a field of data. SQL databases are highly structured and allow for complex queries and operations to be performed on the data. The key features of an SQL database include its ability to handle large volumes of data, its support for data integrity through ACID (Atomicity, Consistency, Isolation, Durability) properties, and its use of SQL for data definition, manipulation, and control. Here's the translation of the explanation into Chinese: 作为一名数据库管理领域的专家，我可以解释 SQL 数据库是一种使用 SQL 语言访问和管理数据的数据库类型。SQL，代表结构化查询语言，是一种为管理关系数据库管理系统（RDBMS）中的数据而设计的标准编程语言。 SQL 数据库被组织成表格，由行和列组成。每个表格代表不同类型的数据结构，其中每行是一个单独的记录，每个列代表一个数据字段。SQL 数据库高度结构化，允许对数据执行复杂的查询和操作。 SQL 数据库的关键特性包括其能够处理大量数据，通过 ACID（原子性、一致性、隔离性、持久性）属性支持数据完整性，以及使用 SQL 进行数据定义、操作和控制。 read more >>
