About data access provider and consumer
I am new to read the book named ¡°Pro ADO.NET 2.0¡±. I am newer too to learn this topic.
Today, I have a question about the ADO.NET model in the figure 1-5
Is ADO.NET the data access consumer?
Are OLE DB and ODBC the data access provider?
Where is the SQL provider or the Oracle provider?
The two providers consist of the ADO.NET?
Or didn¡¯t draw them in the figure?
