Repository Pattern

In Today’s blog will discuss what is the Repository pattern and the benefits of Repository pattern.

Introduction:

Repository pattern is design pattern commonly used in software development, including C# and .Net applications. It is one of the more popular pattern used in software development.

Repository is a class define all the entity with all the database operations.

What is the Repository Pattern?

Repository Pattern is a design pattern that separates the data access layer in application. It’s working like middle layer between business logic and data access layer.

It encapsulates the logic required to access the data source such as database or service.

Using Repository pattern structure we can easily interact with data storage like (database, service etc.). This separation improve the code quality.

Benefits of Repository Pattern:

The Repository pattern is provide clean separation between business logic and data access layer. Improving the maintainability of application.

Using Repository pattern easily we can change the data storage implementation without Modifying any other applications or layers.

Using Repository pattern you can abstract the data access layer details.

One defined repository interface can be reused across multiple parts of the applications. Reducing the code duplication.

Implement Repository Pattern in .Net

Create Interface (Repository): Create Interface and declare the methods which is required for data access operations (e.g., IRepository).

Implement Repository class: Implement new repository class by implementing the repository interface and providing logic to interact with data source (e.g, CustomerRepository)

Inject Repository: now using dependency injection to inject the repository interface in the class constructor to access the data.

Unit of Work Repository Pattern

In the Repository pattern the Unit of Work is a design pattern used to manage one more operations into single transaction scope. If any transaction’s operations is fail, then it will roll back the transaction and if all the operations are successful then it will commit the transaction.
