What is unit of work in Web API?
The Unit of Work pattern is used to group one or more operations (usually database operations) into a single transaction or “unit of work”, so that all operations either pass or fail as one.
Is Unit of Work necessary?
Not necessarily. EF already provides the unit of work pattern for you. The only reason to still have a unit of work is if you: want to include non-EF-datasources in an atomic data operation.
Does repository need pattern?
The Repository pattern may be beneficial where you have many entities and have many complex queries to work with those entities. An extra layer of abstraction in this case can help you to eliminate duplication of query logic.
When to use unit of work in web API 2?
When implementing the Unit of Work and Repository pattern in Web API 2, the web api layer is the responsible for the configuration of dependency injection and transaction management.
Why are repository and unit of work patterns important?
Implementing these patterns can help insulate your application from changes in the data store and can facilitate automated unit testing or test-driven development (TDD). In this tutorial you’ll implement a repository class for each entity type.
How is a repository pattern used in an application?
Repository Pattern is used to create an abstraction layer between Data Access Layer and Business Logic Layer of an application. Repository directly communicates with data access layer [DAL] and gets the data and provides it to the business logic layer [BAL].
How is the repository pattern used in CRUD?
The Repository pattern is used to manage CRUD operations through an abstract interface that exposes domain entities and hides the implementation details of database access code. The domain/business logic layer contains the interfaces for a unit of work and a generic repository.
