Db2 is a family of database management system (DBMS) products from IBM that serve several different operating system (OS) platforms. Used by organizations of all sizes, Db2 provides a data platform for both transactional and analytical operations, as well as continuous availability of data to keep transactional workflows and analytics operating efficiently.

Db2 databases have logical structures and physical structures which the DBMS manages separately. The physical storage of data can be managed without affecting the access to logical storage structures. Db2 databases are created using Data Definition Language, or DDL, commands and are composed of tablespaces, tables with rows and columns, views, indexes, stored procedures and other supporting structures.

Once created, a DBA or developer can use a Db2 database and its underlying structures to create, read, update and delete data to support an organization’s business requirements.

SQL is a domain-specific language used in programming and designed for managing data held in a relational database management system, or for stream processing in a relational data stream management system.

SQL stands for Structured Query Language. SQL lets you access and manipulate databases

SQL became a standard of the American National Standards Institute (ANSI) in 1986, and of the International Organization for Standardization (ISO) in 1987
