SQL

Structured Query Language, abbreviated SQL , sometimes “continuation” for historical reasons), is a domain-specific language used in programming and designed to manage data stored in a management system relational databases (RDBMS) or for flow processing in a relational data flow management system (RDSMS). 

It is particularly useful when working with structured data, i.e. data involving relationships between entities and variables. SQL offers two main advantages over older read/write APIs such as ISAM or VSAM. 

Firstly, it introduced the concept of accessing many records with a single command. Second, it eliminates the need to specify how to reach the record, e.g. with or without an index. Originally based on relational algebra and tuple relational calculus. 

Types of SQL

SQL consists of many types of statements, which can be informally classified as sub-languages, commonly: Data Query Language (DQL) and Data Definition Language (DDL), data control language (DCL) and data manipulation language (DML). The scope of SQL includes data queries, data manipulation (inserts, updates, and deletes), data definition (schema creation, and modification), and data access control. Although SQL is essentially a declarative language (4GL), it also contains procedural elements.
