If you just need something to stash data into that's not complicated and can all fit into a single table, or a group of unrelated tables, this is a nice tool. The problem is, this does not support foreign keys or any kind of back-end logic, so you can't implement one-to-many or many-to-many relationships in the back-end. The whole purpose of having a back-end is to hide business logic that does your filtering for you. This forces you to pull the data from the API into your front-end and implement all of your business logic there. Also, there's a danger in exposing your entire DB schema to the public. Sure, you can hide certain fields, but that's usually what your business logic relies upon to do its own stuff. Given the single-table access limitations, there are free php scripts available that let you generate an API for any MySQL table, including a full swagger interface, and probably other DBs as well.
