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. 4. Integrate it with a repository pattern for better data access.

Can you explain how it integrates with the Repository pattern?

Certainly! The Repository pattern abstracts data access, while the Unit of Work pattern manages the transaction. The Unit of Work can hold multiple repositories, allowing you to commit changes across them in a single transaction, ensuring data consistency.

What are some common pitfalls to avoid?

Common pitfalls include: 1. Keeping the Unit of Work too long-lived, which can lead to memory issues. 2. Not properly handling exceptions, which can leave the database in an inconsistent state. 3. Overusing it for simple operations that don't require transaction management.

How does it affect performance?

When used correctly, the Unit of Work pattern can improve performance by reducing the number of database calls and ensuring efficient transaction management. However, if misused, it can lead to performance bottlenecks, especially if the Unit of Work is kept open for too long.
