Architectural Relationships 

DMaaP is component that provides data movement services that transports and processes data from any source to any target.  It provides the capability to:

• Support the transfer of messages between ONAP components, as well as to other components
  

• Support the transfer of data between ONAP components as well as to other components.

  Data Filtering capabilities

• Data Compression capabilities

• Data routing (file based transport)

• Message routing (event based transport)

• Batch and event based processing

...

3. Component Description:

DMaaP consists of 4 3 software syatemscomponents

• Message Router (MR) - Message Router is a reliable, high-volume pub/sub messaging service with a RESTful HTTP API. It is intended to be deployed by Platform Service providers so that it is available to Platform clients as a web service. The service is initially built over Apache Kafka.
• Data Router (DR) - The Data Routing System project is intended to provide a common framework by which data producers can make data available to data consumers and a way for potential consumers to find feeds with the data they require. The interface to DR is exposed as a RESTful web service known as the DR Publishing and Delivery API
• Data Bus Controller - Provisioning API of the Data Movement Platform that can be used for provisioning topics in the Message Router and feeds in Data Router. In addition Bus Controller is also used for provisioning Mirror Maker capability between two Message Router instances to replicate messages

...

This needs to be updated as this is not likely correct.
