RE: Table Size

Prem - Simple way to get in the ballpark with table size. Figure out how large your average row is and multiply by the number of rows. This is only approximate and you'll want to size larger for indexes and other effects like the fact that your data blocks won't be 100% utilized.

The best way to calculate the size of a table is to load it with 1000 production data rows. Then calculate the size of the predicted volume. You should be able to handle the first year of data at day 1. Do not loose time to calculate the table size at the byte level with formulas. For the temp

New, No guru here, but that is the way that I do it - average row size vs estimated number of rows * fudge factor of 30% plus a little room for underestimation. Also, don't forget room for indexes. I have found this method to be quite successful, since the major hurdle is figuring out how many r
