Discussion
________ is an object-oriented interface that encapsulates data-server functionality.
Answer: B
Correct answer: OLE DB
OLE DB is object-oriented and COM-based: it wraps data-server functionality in objects with defined interfaces, so that a provider can implement the pieces it supports and consumers can use whatever is offered. ODBC is a procedural, SQL-oriented interface by contrast, and ADO is a simplified object cover over OLE DB.
