This chapter discusses the performance issues associated with using the tempdb database. tempdb is used by Adaptive Server users. Anyone can create objects in tempdb. Many processes use it silently. It is a server-wide resource that is used primarily for internal sorts processing, creating worktables, reformatting, and for storing temporary tables and indexes created by users.
Many applications use stored procedures that create tables in tempdb to expedite complex joins or to perform other complex data analysis that is not easily performed in a single step.
