What are the best practices for implementing the Unit of Work pattern?

What are the best practices for implementing the Unit of Work pattern?

The Unit of Work pattern helps manage transactions and coordinate changes to multiple objects. Best practices include: 1. Keep the Unit of Work short-lived. 2. Use it to track changes to entities. 3. Ensure it handles concurrency effectively.

Can you explain how it helps with database transactions?

Certainly! The Unit of Work pattern groups multiple operations into a single transaction, ensuring that either all changes are committed or none at all. This maintains data integrity.

What are some common pitfalls to avoid?

Common pitfalls include: 1. Not disposing of the Unit of Work properly, leading to memory leaks. 2. Overusing it for read-only operations. 3. Failing to handle exceptions correctly.

How does it compare to the Repository pattern?

The Repository pattern focuses on data access and encapsulates the logic for retrieving and storing data, while the Unit of Work pattern manages the overall transaction and coordinates changes across multiple repositories.

Can you give an example of its implementation?

Sure! In a typical implementation, you would create a UnitOfWork class that holds references to repositories and manages the commit and rollback of transactions.
