- I believe that this thread started out as a "can anyone do this REASONABLY"
-
- UNIFY 2000 can handle this (500K rows @ 30K per row). If you have the disk space,
- we have the database. :-)
-
- Mischa is right... its not the users, it's the size of the database. The
- UNIFY 2000 database package can have individual table segments in the 16+Mb
- category, allowing over 500 rows per segment, so the table would only require
- 10000 segments.
-
- You would still have plenty of room for indices and the rest.
-
- Performance is impossible to judge without getting your hands a little dirty.
- It depends on hardware, access patterns, indexing strategies, and a whole lot
- more, but in general UNIFY 2000 is very hard to beat in the performance area.
