This abstract class serves as one of the key extensibility points that comprise the Plugin Datastore Framework. Specifically, each instance of a concrete class that implements this abstraction acts as a conduit between a third-party data source and ArcGIS Pro via the deployment of a plug-in data source add-in.

Currently, the framework only supports ArcGIS.Core.Data.DatasetType.Tables and ArcGIS.Core.Data.DatasetType.FeatureClasss in a read-only manner.
