Unit Of Work
The interface IUnitOfWork represents an atomic operation for the underlying data store. For example, for a SQL database, a class implementing IUnitOfWork shall be a wrapper for IDbTransaction objects.
A unit of work shall group a set of repositories or other kinds of objects designed to access data, which are related in the context of a given operation.
For example, to create an invoice, we may need to create two kinds of entities:
- Invoice
- InvoiceId
- CustomerId
- CreateDate
- Total
- Taxes
- GrandTotal
- InvoiceItem
- InvoiceItemId
- InvoiceId
- ProductId
- Quantity
- Amount
The way of completing such operation from an application-level command handler could be:
public class CreateInvoiceCommandHandler
{
private readonly ISalesUnitOfWork _unitOfWork;
public CreateInvoiceCommandHandler(ISalesUnitOfWork unitOfWork)
{
_unitOfWork = unitOfWork;
}
public async Task<CreateInvoiceCommandResult> HandleAsync(CreateInvoiceCommand command, CancellationToken cancellationToken)
{
// Validate command
var invoice = new Invoice();
// Populate invoice object from properties of command object
// Begin operation
// IUnitOfWork inherits from IDisposable and IAsyncDisposable, if any exception is thrown, the current operation shall be rolled back
_unitOfWork.BeginWork();
// Create the Invoice entity
var invoiceId = await _unitOfWork.InvoiceRepository.CreateAsync(invoice, cancellationToken);
// Create all the InvoiceItem entities
foreach (var item in command.Items)
{
var invoiceItem = new InvoiceItem();
// Populate invoiceItem object from properties of item object
// Create each InvoiceItem entity
await _unitOfWork.InvoiceItemRepository.CreateAsync(invoiceItem, cancellationToken);
}
// Commit the current operation
await _unitOfWork.SaveWorkAsync(cancellationToken);
// Return the result of the operation
return new CreateInvoiceCommandResult
{
InvoiceId = invoiceId
};
}
}
