Is there a limit to the database size or number or users?
SQL Server supports 32,767 databases at a maximum size of 1 terabyte. 2 billion tables per database, 250 columns per table and 32,767 connections per database. For comparison purposes, a Design It! ® database managing 1,000 motors, and 6,000 instruments and all the associated cables and connections will require approximately 100MB of disk space.
