Guys,
We r working on a Datawarehouse solution.
Our Duhvelopers want to merge all code tables into a single table by adding
a codetype column.
with reference to this, i came across this article from Steve's site
http://www.ixora.com.au/tips/design/meta-data.htm
i want to put them into different individual code tables instead of a single
table, for the foll reasons.
1. specific attributes for a particular code type is logically and
physically seperated from other code types.
2. a table lock affects only the concerned code table
3. granular control over the individual code table
i am short of arguments
wld be grateful, if ull can advise me which would be better from performance
perspective.
