| Maybe, but not likely. Probably the last thing I'd consider, well after optimising queries, indexing tables and partitioning, and only if the other DBs were going onto other servers.By splitting DB you incur all sorts of other problems - referential integrity, backup plans, security, etc--Gail ShawSQL Server MVP |
