While migrating Trident from .net framework 3.5 to .net framework 4.0, we did not migrate Web service broker provider due to technical issues. But the OPC provider is still available
in Trident 1.2.1 build.
<< Are the Connections to OPC File and Web Service Broker used to use an XML File, Amazon
S3 and SSDS as Registry?>>
No providers are related to each other from Trident point of view. They should have their own implementation and access details. But providers themselves can be designed in such a way that
they are related to other providers.
Web service broker is a wrapper which is used to expose the data layer as
the WCF web service. The data layer again can be configured to access either the SSDS/Amazon S3/ XML Store.
OPC provider is not as usual providers, but it
is only used to create and import the Trident packages(.twp files).
Please let us know if this answered your questions.
