Max tables in a MySQL database

Question

Is it bad to have too many tables in a database? I have about 160 tables in one database. Is it better to split it into several database rather than using a single database? Sin

Answer 1

160 tables isn't radically huge.

16,000 might be...probably would be...more unreasonable - such databases exist in ERP or CRM systems (even into the 40-50K tables range, but many of those tables are not actually used, or are only barely used).

Even so, the typical DBMS will 'handle' such large databases, but there is more strain on the system catalog than usual in such systems.
