SQL

SQL (Structured Query Language) is the ANSI/ISO standard language for managing and querying relational databases. SQL defines the interface for creating, reading, updating, and deleting data in relational database management systems (RDBMS). Database connectivity standards including ODBC (Open Database Connectivity) and JDBC (Java Database Connectivity) expose SQL capabilities as programmatic APIs, enabling applications to connect to and interact with SQL-compliant databases. Major implementations include MySQL, PostgreSQL, Microsoft SQL Server, Oracle, SQLite, and many others.

SQL publishes 2 APIs on the APIs.io network. Tagged areas include ANSI Standard, Data Management, Database, ISO Standard, and Query Language.

The SQL catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.
