DataProvider RPC
The bundle data-provider is the Web-API for our Database to read, write, update and delete data. The reason for this is the abstraction and exchangeability of the database (currently elasticsearch). Its provided data is specified in the data-provider.yang in the submodule data-provider-model. Each datatype is so called Entity.

The entrypoint for the data-provider is the DataProviderImpl class (org.onap.ccsdk.features.sdnr.wt.dataprovider.impl.DataProviderImpl). Its just handling all the nested services and other provided servlets. The most important part is the DataProviderServiceImpl (org.onap.ccsdk.features.sdnr.wt.dataprovider.impl.DataProviderServiceImpl). This is implementing the Service for the rpc-requests defined by the data-provider.yang so the handler for all our webrequests for the database.

Mediator Gateway Service
Reverse proxy functionality which forwards e.g.
GET /ms/{ms-server-db-id}/api/?task=getconfig
to
{mediator-server-url}/api/?task=getconfig
and forwards response from the server.
