SQL / Structured Query Language

Definition(s)

  • A type of relational database management system (RDBMS). Relationships in a relational database are represented by linkages that exist between two or more pieces of data. The final defining feature of SQL is its ability to return data from one data field based on its relationship with another data field. See also Relational Database Management Systems.
  • SQL is a standard programming language for getting information from and updating a database. Although SQL is a standard, many database products support SQL with proprietary extensions to the standard language. 1
  • The popular standard for running database searches (queries) and reports. 2
  • Structured Query Language, the language used to control traditional relational databases. A relational database stores data in one or more tables. It can also represent relations between the columns of one table (variables in that table) and columns (variables) in another table, hence the name “relational database.” 3
