Architecture

Orm is clearly designed to abstract entities from database implementation; Orm separates your model into three basic layers:

  • Entities

    Entities are data crates, hold your data, validate values and provide API for value encapsulation, e.g. for relationships.

  • Repositories

    Repositories form a layer which takes care about your entities. Repositories manage entities and provide an API for their retrieving, filtering and persisting.

  • Mappers

    Mappers are the backend of Orm. Mappers provide interaction with the database layer. Orm users Nextras\Dbal database library as abstraction layer for database connection.

All layers are connected in the central Model class. Each entity must have defined its own repository and mapper.
