Data definition language (DDL), Data manipulation language (DML), Data control language (DCL), Transaction Control Statement (TCS), and Session Control Statements are the five types of SQL statements (SCS).
Relational and non-relational databases are the two types of databases. There are two types of database management systems: relational and non-relational, usually known as SQL and NoSQL, respectively.
SQL is the most widely used programming language for retrieving and organising data from relational databases. A table with rows and columns is referred to as a database. The language of databases is SQL. It makes it easier to extract specific data from databases, which can then be used for analysis.
The Data Manipulation Language (DML), Data Definition Language (DDL), and Data Control Language (DCL) are the three basic components of SQL (DCL).
SQL statements are used to conduct operations like updating data in a database and retrieving data from one. Oracle, Sybase, Microsoft SQL Server, Microsoft Access, Ingres, and other relational database management systems that use SQL are just a few examples.
