Visual Basic Concepts
OLE DB is a new low-level interface that introduces a "universal" data access paradigm. That is, OLE DB is not restricted to ISAM, Jet, or even relational data sources, but is capable of dealing with any type of data regardless of its format or storage method. In practice, this versatility means you can access data that resides in an Excel spreadsheet, text files, or even on a mail server such as Microsoft Exchange.
In Visual Basic 6.0, you leverage the flexibility of OLE DB through ADO, the programmer interface to OLE DB.
OLE DB is not designed to be accessed directly from Visual Basic due to its complex interfaces. Instead ActiveX Data Objects (ADO) encapsulates and exposes virtually all of OLE DB’s functionality.
