I think many programmers ignore or underestimate the capability of the systems software to do performance tuning. They should first explore what the DB server and the hardware can do before going down the path of denormalization. You are right, Vijil.

Instead they should use features like Materialized Query tables (DB2) or materialized views (Oracle) that can improve performance transparently. DB2 for example, can suggest best MQTs automatically based on a workload and the performance improvements are easily measurable. <br/><br/>Vijil<br/><br/>See:http://www.ibm.com/developerworks/data/library/techarticle/dm-0708khatri/index.html My personal opinion is that a programmer should NOT do explicit denormalization to improve performance, except in very special circumstances.
