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
WordPress Multisite creates dozens of tables for every new subsite in the same database.
So you can be so good at only 160 tables.
It might be an issue to manage them with PhpMyAdmin or other software to see and scroll through the tables. But if you work with the code it should not be a problem.
