Microsoft ADO.NET is a standard database API for the Microsoft .NET development platform. The MacroView ADO.NET Provider is an implementation of the .NET API that allows .NET programs to connect to and access data from MacroView systems. This provider implements the client side of the MetaServer Protocol and thus can be used to communicate to and extract data from both the MacroView MetaServer service and the OPC MetaBridge service. Connection to both of these services is possible because they both implement the MetaServer Protocol.
The MacroView ADO.NET Provider allows developers to create arbitrary applications that either retrieve data or update data in the services they connect to. It includes a series of sample applications as part of the product. A screen shot from one of these sample applications is displayed below. In this particular screen capture, the entity list on the server is displayed. The entity list displayed is a flattened OPC hierarchy from the Matrikon OPC Simulation server.
