It would be great if there were a way to estimate the storage space needed to store each table in the schema.
For example, depending on how many columns and their types you can estimate how much storage a row in each table will require and then project that out to 500,000 rows.
I realize it gets tricky with indexes, different server technologies, etc. but an estimate of raw data storage might help when looking for opportunities to reduce data duplication.
