SQL/DS (Structured Query Language/Data System) was IBM's first commercial implementation for its mainframe computers of a DBMS (Database Management System) built around the SQL language. SQL/DS is an (imperfect) software implementation of Dr. E. F. Codd's Relational Model for data management. SQL/DS ran on the DOS/VSE and VM/CMS operating systems. It came to market in the early 1980s. A little later, IBM also introduced DB2, another SQL-based DBMS, this one for the MVS operating system.

  • SQL/DS (Structured Query Language/Data System) was IBM's first commercial implementation for its mainframe computers of a DBMS (Database Management System) built around the SQL language. SQL/DS is an (imperfect) software implementation of Dr. E. F. Codd's Relational Model for data management. SQL/DS ran on the DOS/VSE and VM/CMS operating systems. It came to market in the early 1980s. A little later, IBM also introduced DB2, another SQL-based DBMS, this one for the MVS operating system. The two products have coexisted since then; however, SQL/DS was rebranded as "DB2 for VM and VSE" in the late 1990s.
  • SQL/DS (Structured Query Language/Data System) は、データベース言語SQLを採用したメインフレームコンピュータ用データベース管理システム (DBMS) であり、IBM初の商用関係データベース管理システム (RDBMS) 製品である。 SQL/DS はエドガー・F・コッドのデータ管理の関係モデルを実装したソフトウェアである（ただし、完全ではない）。 SQL/DS は VSE および VM/CMS オペレーティングシステム上で動作する。1980年代初期に市場に登場した。ほどなくしてIBMはDB2をリリースした。こちらもSQLベースのDBMSであり、MVSオペレーティングシステム上で動作した。これら2製品はその後共存したが、SQL/DSは1990年代後半に"DB2 for VM and VSE"と名称を変更した。
