A message flow project is a specialized container in which you create and maintain all the resources associated with one or more message flows.
You can create a message flow project to contain a single message flow and its resources, or you can group together related message flows and resources in a single message flow project to provide an organizational structure to your message flow resources.
Message flow project resources are created as files, and are displayed within the project in the Broker Development view. These resources define the content of the message flow, and additional objects that contain detailed configuration information, in the form of ESQL modules and mappings, for one or more nodes within the message flow.
