• Using DB2 Compression feature at table and index level, and their impact on space saving and resource usage was explored on a terabyte warehouse database system

• Examining Performance Improvement on query workloads and maintenance routines

• Benchmarking test data (normalized for comparison) to illustrate the performance impact by enabling compression feature

• Inline Large OBject (LOB) data, XML data compression, and backup compression feature were also tested

• Temp table compression data was observed
