number of 'databases'?

[twoeyedziggy]

when a certain plan says it can host 20 or 50 or 100 "databases" is that the number of tables, or whole databases? if it is the number of full databases, is there a limit on the number of tables/records per database(beyond your plan's storage capacity)?

That is a number of "databases" each of which can hold as many tables as you need it to. Since all the "databases" on a server are in fact saved as a single database the only real differences between using one or many databases are:

1. portability if some tables belonging to a specific site may need to be moved to different hosting.
2. ease of setting up user access since there are tools to specifically grant a given user global access within a "database" whereas you'd need to run the SQL GRANT commands yourself if you want to restrict the access to specific tables.
