I looked at that earlier but couldn't figure out how to use aggregate functions like "GROUP BY ..." or "AVG(...)".
I'm would like to make the database do the math for me, for example to determine the average value of a column in a given time span rather than having to traverse hundreds of rows manually in a script and summing up and dividing. I think the database will make it faster and more robust than anything I can think up :-)
