Leslie
It was taken out because there are so many variations and permutations possible that a generic formula is never going to be realistic. The only realistic way to get space estimations is to load a "typical" set of data (whatever that is) and then extrapolate to Production sizes, based on history and so on.

Subject: Lost appendix: Space Estimations for Schema Objects
The Oracle 8.0 documentation had an Appendix A to the "Oracle Server Administrator's Guide" on "Space Estimations for Schema Objects". It gave formulas for approximating the amount of disk space that would be taken up by tables and indexes, taking into account block size, init trans, pct free, etc. The appendix seems to have vanished in the 9i documentation -- at least I can't find it.
Does anyone know if/where this information still exists, either in the Oracle documentation set or some other documentation?
Thanks,
Leslie
