Information on minimum hardware and/or RAM requirements

I was wondering if you could tell me where to find information on minimum hardware and/or RAM requirements for different size databases to handle proper speed in real time relational database applications.

There is a relatively simple formula for converting a programmer's (or marketing department's) estimate to a "real world" estimate. Any estimate has two parts; one part is numeric, and the other is a unit of measure. To convert the marketing estimate to real world, you double the numeric part, then switch to the next larger unit of measure.

For example, if the marketing department expects it to take two hours to install their product, you need to double the two to get four, and promote the hours to days. Therefore it should take about four days to install their product.

Apply this formula to the published hardware and RAM specifications for any database, and you should have a pretty good real world estimate of the actual resources that you'll need.

On a slightly more serious note, the configuration of most database products is much more of an art than a science. The manufacturer has a vested interest in seeing the smallest possible numbers published, even though their tech support people will probably scream at marketing for publishing those numbers. Over estimate wildly what the manufacturer suggests, and you'll still probably want more once everything is said and done!
