Drupal 8. Entity API

Entity types in core come in two variants. Content & Config

 The Entity System is the API for entities manipulation (CRUD: create, read, update, delete). Entity validation has its own API (which could validate an Entity saved via REST, rather than a form, for example).

Entities are typed classes with methods

Configuration Entity

Used by the Configuration System. Supports translations and can provide custom defaults for installations. Configuration entities are stored within the common config database table as rows.

Content Entity

Consist of configurable and base fields, and can have revisions and support translations. Content entities are stored within a custom database table as rows. The table name is the same as the content entity "id", and the columns are defined by the entity's "baseFieldDefinitions" method.

Annotations

Annotations are read and parsed at runtime by an annotation engine. Drupal 8 uses the Doctrine annotation parser, which turns it into an object that PHP can use.
