Components of an OLE DB connection
When you access an OLE DB data provider in PowerBuilder, your
connection goes through several layers before reaching the data
provider. It is important to understand that each layer represents
a separate component of the connection, and that each component
might come from a different vendor.
Because OLE DB is a standard API, PowerBuilder uses the same
interface to access every OLE DB data provider. As long as an OLE
DB data provider supports the object interfaces required by PowerBuilder, PowerBuilder can access
it through the OLE DB interface.
Figure 4-1 shows
the general components of a OLE DB connection.
