LoopBack database connectors implement create, retrieve, update, and delete operations as a common set of methods of PersistedModel. When you attach a model to a data source backed by one of the database connectors, the model automatically acquires the create, retrieve, update, and delete methods from PersistedModel. The data access methods on a persisted model are exposed to REST by default; see PersistedModel REST API for the endpoints.
You can connect models using relations to reflect relationships among data. For more information about relations, see Creating model relations.
