Database size estimation tool

Question

Is there a tool for estimating the size of a database?

I am looking for such a tool, which I can input the estimated tables, row size, data types, indexes and other variables to give me a clue about the size of a yet-non-existing database.

I know MS Sql Server Books Online has a good documentation on how to estimate but I don't want to end up coding it :)

Answer 1

Sybase PowerDesigner is able to calculate database size from the model, requiring you only to estimate row numbers for each table.
