Replace the OleDb Provider. DataDirect Connect for .NET supplies managed providers for Oracle, SQL Server, DB2, and Sybase that improve data-access performance. DataDirect Connect's classes and members have the same names as OLE DB's, except that you replace "OleDb" with "Oracle", "Sybase", "DB2," or "SQLServer." (For example, "OracleConnection" replaces "OleDbConnection.")
