At the core of a CRUD API is the database that Graphback interacts with by providing a rich set of tools and APIs that help you get your database working with your GraphQL application in minutes.
Graphback has a CRUD abstraction with a number of out-of-the-box implementations for PostgreSQL, MongoDB databases. SQLite database is also partially supported and we do not recommend using it in production environment, however it is a good choice for testing or development purposes.
Additionally, Graphback integrates with GraphQL Migrations so that you can migrate your databases using your business models defined in the GraphQL schema.
GraphQL Migrations only operates on relational databases e.g PostgreSQL and does not work with MongoDB as shown in the compatibility table below.
