About IBM Db2

IBM Db2 is a family of enterprise relational database products from IBM. It targets transaction processing and analytics that an organization cannot afford to lose, and IBM markets the current generation as an autonomous database that uses AI to help with tuning, monitoring and administration.

The line includes Db2 Database as the core relational engine for structured data, Db2 Warehouse for in-memory analytical queries across multiple sources, and Db2 Genius Hub, an AI-powered console that correlates performance signals across a Db2 estate. IBM has also announced a serverless technical preview aimed at developers and AI agents, and lists Db2 12.1.5 as a recent release.

Db2 can be deployed on any cloud, in hybrid environments or on-premises, so it can run on your own infrastructure as well as in managed cloud settings. It is commercial software with a free trial available, and it suits large organizations with heavy transactional or warehouse workloads, especially those already invested in IBM platforms.
