Answer to Question 1
First, by breaking the features of the DBMS into different objects, vendors have the option of implementing only a portion of their product in OLE DB. This is significant since the all-or-nothing approach required with ODBC was a major disincentive to vendors because of the large investment necessary to achieve ODBC compliance. OLE DB allows the vendor to increase their OLE DB participation in a piecemeal fashion. Second, it allows vendors to create multiple interfaces to their products that have different properties and methods exposed. This improves flexibility for data consumers since they can select an interface that only provides the methods they need, and it is more flexible for data providers since they can change the implementation of an interface without negatively impacting their data consumers.
