Db2 (Database 2)

What is Db2 (Database 2)?

Created by IBM, Db2 is primarily a relational database management system (DBMS), although recent versions allow for some object-relational and non-relational functioning. It stores, retrieves, and manages data.

How does Db2 work?

Data is categorized into tablespaces and can be retrieved through queries, using SQL. The database uses schemas and indexes to organize data.

Db2 and SQL (Structured Query Language)

SQL was developed by IBM in for use in its DBMS at the time, System R (which was succeeded by DB2). SQL eventually became the primary language used for managing databases.
