Microsoft Data Access Components - Wikipedia, the free encyclopedia. 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. Its components include: Active. X Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC). There have been several deprecated components as well, such as the Microsoft Jet Database Engine, MSDASQL (the OLE DB provider for ODBC), and Remote Data Services (RDS).

From the moment I walk through the front doors I am treated like royalty. A Voluntary Product Accessibility Template, or VPAT, is a standardized form developed by the Information Technology Industry Council to show how a product or service.

Some components have also become obsolete, such as the former Data Access Objects. API and Remote Data Objects. The first version of MDAC was released in August 1.

At that time Microsoft stated MDAC was more a concept than a stand- alone program and had no widespread distribution method. Later Microsoft released upgrades to MDAC as web- based redistributable packages. Eventually, later versions were integrated with Microsoft Windows and Internet Explorer, and in MDAC 2. SP1 they ceased offering MDAC as a redistributable package. 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.

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 providers and ODBC drivers), and the database itself.

These component layers are all made available to applications through the MDAC API. The Microsoft SQL Server Network Library, a proprietary access method specific to Microsoft SQL Server, is also included in the MDAC. 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. Naturally, developers still have the choice of writing applications which directly access OLE DB and ODBC. Microsoft SQL Server Network Library. Though Net- Lib is specific to the SQL Server, Microsoft includes it with MDAC.

The SQL Server uses the Open Data Services (ODS) library to communicate with Net- Lib, which interfaces directly with the Windows NT operating system line's Win. The SQL Server Network Library is controlled through the use of a Client Network Utility, which is bundled with the SQL Server. Each Net- Lib supported network protocol has a separate driver (not to be confused with a device driver), and has support for a session layer in its protocol stack. There are two general types of Net- Lib: the primary and the secondary. 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 named pipes network libraries (named pipes are a method of communicating with other processes via a system- persistent pipeline that is given an identity). The Microsoft OLE DB Provider for SQL Server (SQLOLEDB) communicates via primary Net- Libs.

The Super Socket Net- Lib deals with inter- computer communications and coordinates the secondary Net- Libs . The Banyan VINES, Apple. Talk, Server. Net, IPX/SPX, Giganet, and RPC Net- Libs were dropped from MDAC 2. 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 Super Socket Net- Lib also handles data encryption via the use of the Windows SSL API. Safe Hindi Song Downloading Sites.

The Shared Memory Net- Lib, on the other hand, manages connections between multiple instances of SQL Server that exist on one computer. It uses a shared memory area to communicate between the processes. This is inherently secure; there is no need for data encryption between instances of SQL Server that exist on one computer as the operating system does not allow any other process access to the instances' area of shared memory.

Net- Lib is also able to support the impersonation of a logged in user's security context for protocols that support authenticated connections (called trusted connections). This allows Net- Lib to provide an integrated logon authentication mechanism via the use of Windows Authentication.
