Command handling

In this chapter we will cover the process of handling and dispatching commands within an Axon application in more detail. Topics like Aggregate modelling, external command handlers, command dispatching and testing will be covered here. For a more in depth explanation of what a Command Model or Aggregate is we recommend reading the DDD and CQRS concepts chapter.
