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 to avoid memory issues. 2. Use it in conjunction with a repository pattern for better separation of concerns. 3. Ensure that all changes are tracked and committed in a single transaction.

Can you explain how it works with the Repository pattern?

Certainly! The Repository pattern abstracts data access, allowing the Unit of Work to manage multiple repositories. When you call the Unit of Work's commit method, it ensures that all changes across the repositories are saved in a single transaction, maintaining 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 simple operations, which can add unnecessary complexity. 3. Failing to handle exceptions properly, which can leave the system in an inconsistent state.

How does it improve performance?

The Unit of Work pattern can improve performance by reducing the number of database calls. Instead of saving changes immediately, it batches them into a single transaction, which minimizes round trips to the database and can lead to better performance.
