I agree with the CIO.
Sooner or later, the summary table will bite you.
As Hugo says, a view solves the problem.
If the CIO complains about the view, well..

>So, instead of one stop shopping using the summary table the CIO says we have to go to each history data table and pull the max address or whatever.

>Opinions?
Anyone who does not go overboard- deserves to.
