For many years I worked with Northwind database as evidence of "new technologies". That is, Microsoft changed the data access technology and I tested the technology in this database.

Now what I like to do is migrate the knowledge of the model database to new architectures and database, as CQRS and MongoDB. So I will apply effective aggregate design as explained Vaughn Vernon.

If the forces leave me, I will put a bus - a Directbus own or NServiceBus.
