The latest version of MDAC (2.8) consists of several interacting components, all of which are Windows specific except for ODBC (which is available on several platforms). ). MDAC architecture may be viewed as three layers: a programming interface layer, consisting of ADO and ADO.NET, a database access layer developed by database vendors such as Oracle and Microsoft (OLE DB, .NET managed ...
Remote Data Objects (abbreviated RDO) is an obsolete data access application programming interface primarily used in Microsoft Visual Basic applications on Windows 95 and later operating systems. [1] This includes database connection , queries, stored procedures, result manipulation, and change commits.
Programmers usually use such a bridge when a given database lacks an OLE DB provider, but is accessible through an ODBC driver. Microsoft ships one, MSDASQL.DLL, as part of the MDAC system component bundle, together with other database drivers, to simplify development in COM-aware languages (e.g. Visual Basic).
Jet 2.0 was replaced with Jet 2.1, which used the same database structure but different locking strategies, making it incompatible with Jet 2.0. Jet 3.0 included many enhancements, including a new index structure that reduced storage size and the time that was taken to create indices that were highly duplicated, the removal of read locks on ...
Version 3 of the embedded Visual Basic, Visual J++, and Visual C++ tools approximate the language and implementation of Visual Basic 6.0, Visual J++ 6.0, and Visual C++ 6.0. The CD-Roms for installation of these tools have been provided for free from Microsoft. [6] A further update of the latter, version 4.5, is also available.
