Defining Entities in Doctrine ORM

Doctrine

Description

Defining entities in the Doctrine ORM framework and reflecting them in the persistence layer (e.g.: database).

Goals

I know

• the different types of relationships between entities
• what collections are used for
• that collections are necessary when defining "to-many" relationships
• different types of identifier creation strategies

I can

• define an entity class
• define mappings for entities with a mapping type of my choice
• use a collection to define a "to-many" relationship
• use the Doctrine ORM CLI to validate and generate a schema
