DB2 for i (formerly known as DB2 for i5/OS) is an advanced, 64-bit Relational Database Management System (RDBMS) that leverages the On-Demand features of IBM’s Power System. A member of IBM’s leading edge family of DB2 products, DB2 for i supports a broad range of applications and development environments at a lower cost of ownership due to its unique autonomic computing (self-managing) features.
Autonomic Computing Features
The tight integration of DB2 with i provides unique attributes to this RDBMS. Single Level Store and the Object Based Operating System, IBM i (formerly i5/OS), minimize the effort required to manage the database, while maintaining the mainframe-like reliabilty and security. Automation of many of the common Database Administrator (DBA) tasks required by other RDBMS’s is a cornerstone of DB2 for i lower cost of ownership.

Open Development Environments
DB2 is uniquely suited to support many different development environments through adherence to existing and emerging open standards and continued investment protection of heritage programming interfaces. Whether you develop in traditional environments like RPG or COBOL, utilize Java/J2EE or Web Services through
IBM’s Websphere suite of products, or develop using many of the AD tools on the marketplace including Microsoft’s .NET Framework, DB2 can simplify the I/T infrastructure.
Scalability
DB2 for i5/OS leverages the On-Demand capabilities of the IBM Power System platform, including Dynamic Logical Partitioning and On/Off Capacity Upgrade on Demand to simply and quickly respond to changing workloads to ensure business continuity in a dynamic environment. DB2’s sophisticated cost-based query optimizer, unique single level store architecture, and
database parallelism feature allow the database to scale near linearly within an SMP configuration. Recent benchmarks highlight DB2’s performance in a real world, mixed workload environment.
