Most web applications that manage data in a database perform at least some form of create, read, update or delete (CRUD) operations on stored records. Moreover, web applications also often expose those operations via a REST API. Most database tables - corresponding to the entities manged by the application - need their own CRUD controller and set of HTTP endpoints.

Auto CRUD has been developed to reduce this workload.
