As we began our Java adventure at Amway Corp 10 years ago,
one of the most important tasks we had to do was to create our Object Model.
We had a variety of Java objects that we were planning to use in our application.
How were they going to be "wired" together inside of the application?
After 4 weeks of Object-Oriented, J2SE, J2EE training; we set out to define our Object Model.
This model was...

ScalaTest is a xUnit style testing framework. An actor is an object that can be reached through an address, processes messages from a mailbox and sends messages to other actors using the same type of addresses. An actor encapsulates state; it does not share this state with anyone. An actor has behavior, it does something specific with the messages it receives. This article, based on a portion of chapter 2 from Akka in Action, shows how to test actors and send one-way messages.
Bigtable systems are important NoSQL data architecture patterns because they can quickly scale to manage large data volumes. They are also known to be closely tied with many MapReduce systems.
