What is SQL?
SQL, or Structured Query Language, is a programming language designed for managing and manipulating relational databases. It is a domain-specific language used to interact with relational database management systems (RDBMS), which are systems that manage and organize data in a tabular form, with rows and columns.
Key features of SQL include:
- Data Query Language (DQL)
- Data Definition Language (DDL)
- Data Manipulation Language (DML)
- Data Control Language (DCL)
- Transaction Control Language (TCL)
Data Query Language (DQL): SQL allows users to query the database to retrieve specific information using SELECT statements. Queries can involve one or more tables, and filtering and sorting can be applied to the results.
Data Definition Language (DDL): DDL statements are used to define the structure of the database. This includes creating and modifying tables, specifying constraints, and defining relationships between tables.
Data Manipulation Language (DML): DML statements are used to manipulate data stored in the database. This includes inserting new records, updating existing records, and deleting records.
Data Control Language (DCL): DCL statements control access to data within the database. This includes statements like GRANT and REVOKE, which are used to give or revoke permissions to users.
Transaction Control Language (TCL): TCL statements are used to manage transactions in the database. Transactions ensure the integrity of the database by grouping a set of operations into a single unit that is either completed entirely or not at all.
SQL is used in a variety of applications, including web development, data analysis, business intelligence, and more. It provides a standardized way to interact with and manage relational databases, making it a fundamental skill for anyone working with databases and data-driven applications. Some popular relational database management systems that use SQL include MySQL, PostgreSQL, SQLite, Oracle Database, Microsoft SQL Server, and others.
