Architecture

When OLE DB is the interface used for data access, the application is called the OLE DB data consumer, and the middleware program is called the OLEDB data provider.

In the case of PI OLEDB Enterprise, the data consumer relies on the PI OLEDB Enterprise data provider to recognize the format of PI System data stores and provide access to it.

The PI OLEDB Enterprise data provider:

• Accepts requests for data from the application

• Accesses the data from the PI System

• Returns the data to the application
