IBM DB2 Dataserver is a database software for database management and optimization. It offers leading performance, scale and reliability and is optimized to deliver leading performance across multiple workloads, while lowering administration, storage, development, and server costs.

DB2 offers the following features and benefits.

• Autonomics - DB2 includes numerous autonomic features, such as the Self-Tuning Memory Manager, that free database administrators from many common administration tasks. As a result, database administrators can spend less time administering the system and more time focusing on other activities that benefit the business.
• Data Compression - DB2 can dramatically reduce that cost with industry leading data compression technologies that compress rows, indexes, temporary tables, LOBs, XML, and back-up data with compression rates that can reach over 80%.
• Performance Optimization - Gives you the insight and ability to optimize workload execution and increases database productivity.
• PureScale - DB2 pureScale uses a cluster-based, shared-disk architecture to offer easy scalability and high availability. DB2 pureScale allows you to scale the database without tuning the system and requires minimal changes to application code.
• PureXML - With native XML support only provided by DB2, the benefits of XML extend to the database and include the ability to easily evolve an XML schema in minutes to match the application changes without updating the existing table schema or the existing XML data in that table
• Security - Unauthorized data access is an ever present threat that can end up costing business considerable sums of money, their reputation, or both. DB2 offers a comprehensive suite of security features that effectively and decisively minimize this threat.
• Reliability - DB2 can minimize the downtime associated with many planned activities - such as altering a table - and many unplanned events - such a power outage - by either eliminating the downtime completely or reducing it's duration to a few seconds.
