Databases

Introduction

The Hasura GraphQL engine automatically generates your GraphQL schema and resolvers based on tables/views in your database . You don't need to write a GraphQL schema or resolvers. See How Hasura GraphQL engine works for more details.

The Hasura console gives you UI tools that speed up your data-modelling process, or working with your existing databases. The console also automatically generates migrations or metadata files that you can edit directly and check into your version control.
