MICROSOFT ACCESS DATA TYPES OLEDB WINDOWS
Developers of Windows applications are encouraged to use ADO or ADO.NET for data access, the benefit being that users of the application program are not constrained in their choice of database architecture except that it should be supported by MDAC. The Microsoft SQL Server Network Library, a proprietary access method specific to Microsoft SQL Server, is also included in the MDAC.
These component layers are all made available to applications through the MDAC API. NET managed providers and ODBC drivers), and the database itself. 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. 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).
1.1 Microsoft SQL Server Network Library.MDAC is now known as Windows DAC in Windows Vista. The current version is 2.8 service pack 1, but the product has had many different versions and many of its components have been deprecated and replaced by newer Microsoft technologies. Throughout its history, MDAC has been the subject of several security flaws, which led to attacks such as an escalated privileges attack, although the vulnerabilities were generally fixed in later versions and fairly promptly. Eventually, later versions were integrated with Microsoft Windows and Internet Explorer, and in MDAC 2.8 SP1 they ceased offering MDAC as a redistributable package. Later Microsoft released upgrades to MDAC as web-based redistributable packages. At that time Microsoft stated MDAC was more a concept than a stand-alone program and had no widespread distribution method. The first version of MDAC was released in August 1996. Some components have also become obsolete, such as the former Data Access Objects API and Remote Data Objects. There have been several deprecated components as well, such as the Jet Database Engine, MSDASQL (the OLE DB provider for ODBC), and Remote Data Services (RDS). Its components include: ActiveX Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC). Microsoft Data Access Components ( MDAC also known as Windows DAC) is a framework of interrelated Microsoft technologies that allows programmers a uniform and comprehensive way of developing applications that can access almost any data store.
