Creating a database

Hey, I was thinking about a new project and realized I could use databases as a storage of information that is working in the long term. The problem is I have no idea, on how to build one in glitch. It should be possible to use get and put requests from a different software to connect with the db, anyone know how to create this?

what databases do you have experience in? there’s a SQLite starter project you can look at if relational databases are suitable.

As I understood, I can’t access them with a different application, is that right?

the databases are files, and SQLite itself is a library. so different applications with that library and with access to that file can access them

But how do I set them up to be accessible?

what are the other applications that need to access it? are they other programs in the same project?
