Define Action/Function on the Domain Models.

Using the actions implement the partially focused business logics, and use the functions implement complex queries.

Hook

Hook is general business logic for specify Domain Model, like beforeCreate/beforeUpdate, and it's mapped from OData/HTTP Method.

Define Hooks to implement the general business logics for entity.

Each model will have its own standard CRUD service which enhanced with hooks logic.

Transaction

Each TransactionContext will use single database transaction (connection).
