The Super Socket Net-Lib also handles dataвЂ…encryption via the use of the Windows SSL API. The Network Library router had the job of managing all these protocols, however now only the named pipes secondary Net-Lib is managed by the router. The BanyanвЂ…VINES, AppleTalk, ServerNet, IPX/SPX, Giganet, and RPC Net-Libs were dropped from MDAC 2.5 onwards. The Super Socket Net-Lib deals with inter-computer communications and coordinates the secondary Net-Libs вЂ“ though the TCP/IP secondary Net-Lib is an exception in that it calls on the WindowsвЂ…SocketsвЂ…2 API directly. The Microsoft OLE DB Provider for SQL Server (SQLOLEDB) communicates via primary Net-Libs. The primary Net-Lib consists of a Super Socket Net-Lib and the Shared Memory Net-Lib, while there are numerous secondary Net-Libs, including TCP/IP and namedвЂ…pipes network libraries (named pipes are a method of communicating with other processes via a system-persistent pipeline that is given an identity). There are two general types of Net-Lib: the primary and the secondary.

The SQL Server Network Library is controlled through the use of a Client Network Utility, which is bundled with the SQL Server.Д®ach Net-Lib supported network protocol has a separate driver (not to be confused with a deviceвЂ…driver), and has support for a sessionвЂ…layer in its protocol stack. The SQL Server uses the Open Data Services (ODS) library to communicate with Net-Lib, which interfaces directly with the WindowsвЂ…NT operating system line's Win32 subsystem. Though Net-Lib is specific to the SQL Server, Microsoft includes it with MDAC. The Microsoft SQL Server Network Library (also known as Net-Lib) is used by the Microsoft SQL Server to read and write data using many different networkвЂ…protocols. Naturally, developers still have the choice of writing applications which directly access OLE DB and ODBC. 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 MicrosoftвЂ…SQLвЂ…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 ( OLEвЂ…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). MDAC is now known as Windows DAC in WindowsвЂ…Vista. The current version is 2.8 serviceвЂ…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 securityвЂ…flaws, which led to attacks such as an escalatedвЂ…privilegesвЂ…attack, although the vulnerabilities were generally fixed in later versions and fairly promptly. Eventually, later versions were integrated with MicrosoftвЂ…Windows and InternetвЂ…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 DataвЂ…AccessвЂ…Objects API and RemoteвЂ…DataвЂ…Objects. There have been several deprecated components as well, such as the MicrosoftвЂ…JetвЂ…DatabaseвЂ…Engine, MSDASQL (the OLE DB provider for ODBC), and RemoteвЂ…DataвЂ…Services (RDS). Its components include: ActiveXвЂ…DataвЂ…Objects (ADO), OLEвЂ…DB, and OpenвЂ…DatabaseвЂ…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.
