Well, they do and they don't. Many dbms products allow for various indexing and clustering schemes. Far more options are needed and the scope of the physical dbms should be much broader than it is now. Perhaps with the advent of multi-core chips and cloud computing dbmses will start expanding that scope. Received on Fri Nov 14 2008 - 23:24:54 CET
