However, we have an OLE DB provider for ODBC, it is a general purpose provider with help of this ADO can access any Data source which can understand ODBC.Дatabase (DB) is a collection of information organized in such a way that a computer program can easily understand and read the data.

Most of the times OLE DB providers are specific to a particular Data Source Type. ADO canвЂ™t access the data source directly, it will take help of OLE DB Provider to communicate with the data source.
