What is the Unit of Work pattern in software development?

The Unit of Work pattern is a design pattern that maintains a list of objects affected by a business transaction and coordinates the writing out of changes. It helps manage database transactions and ensures that all changes are committed or rolled back together.

Can you give me an example of how it works?

Sure! Imagine an e-commerce application where a user places an order. The Unit of Work would track changes to the order, inventory, and payment details. When the user confirms the order, the Unit of Work commits all changes to the database in one transaction.

What are the benefits of using the Unit of Work pattern?

The benefits include improved performance by reducing database calls, better transaction management, and easier handling of complex business logic.

Are there any drawbacks to using this pattern?

Yes, potential drawbacks include increased complexity in the codebase and the need for careful management of the Unit of Work lifecycle.
