Cache Money

That's how I makes it rain

I was reading the Voice of the DBA and it referred to a post by Brent Ozar about caching at the database level.  After discussing it with my homey, he thought it sounded a lot like memoization (I like to say it with a 3 stooges voice, mem moy Zay Shun).  According to wiki, Memoization is a specific case of optimization, which seems to be what we are doing when we cache the results of a stored procedure.

Workload Simulation With SQL Data Generator
