What are some examples of the Unit of Work pattern?

The Unit of Work pattern is used to manage transactions in a way that ensures all operations are completed successfully. For example, in a shopping cart application, you might use it to handle adding items, updating inventory, and processing payments as a single transaction.

Can you give me a code example?

Sure! Here's a simple C# example:

public class UnitOfWork : IUnitOfWork
{
    private readonly DbContext _context;

    public UnitOfWork(DbContext context)
    {
        _context = context;
    }

    public void Commit()
    {
        _context.SaveChanges();
    }

    public void Rollback()
    {
        // Logic to rollback changes
    }
}

What are the benefits of using this pattern?

The benefits include better transaction management, reduced database calls, and improved performance by batching operations.

Are there any drawbacks?

Yes, potential drawbacks include increased complexity and the risk of holding onto database connections longer than necessary.
