Robert, one of the supported databases is MySQL so you’d be okay with that connector piece of it at least. Prisma would create tables based on the modelds that you defined in your schema

Stepen — Thanks — but I’m wondering whether it’s possible to connect to an existing database with data. Prisma can do introspection, which, as I understand it, will create the schema based on existing tables, but it only works with PostgreSQL as far as I can see…

Yeah it looks like it's only available for PostgresSQL at the moment. Found this issue regarding introspection for MySQL https://github.com/prisma/prisma/issues/2506. There's a PR in that thread that may work for you.
