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.
Microdoft that time Microsoft stated MDAC was more a concept than a stand-alone program and had no widespread distribution method. Throughout its history, MDAC has been the subject of several security flawswhich led to attacks such as an escalated privileges attackalthough the vulnerabilities were generally providr in later versions and fairly promptly. The current version is 2. The latest version of MDAC 2. Нажмите сюда 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.
Each Net-Lib supported network protocol has a separate driver not to be confused with a device driverand has support for a session layer in its protocol stack. There are two general types of Net-Lib: the primary and the secondary.
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. It uses a shared memory area to communicate microsoft office access 2007 ole db provider free 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 жмите 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.
Windows Authentication is not supported on Windows 98 or Windows Me. Microsoft has used this technology to separate the application from data can store in the website the data store that it needs to access. This was microsoft office access 2007 ole db provider free because different applications need access to different types and sources of data, and do not necessarily need to know how to access technology-specific functionality.
The technology is conceptually divided into consumers and providers. However, because different data store technology can have different capabilities, OLE DB providers may not implement every possible interface available. Microsoft calls the availability of an interface to be “provider-specific” as it may not be applicable depending on the database technology involved.
Additionally, however, providers may also augment the capabilities of a data store; these capabilities are known as services in Microsoft parlance. Universal data link files or ‘. A user can use a Data Link Properties dialog box to save connection information in a.
Consequently, these files provide a convenient level of indirection. Additionally, the dialog box specifies a number of alternate OLE DB data providers for a variety of target applications. Open Database Connectivity ODBC is a native interface that is accessed through a programming language usually C that can make calls into a native library. A separate module or driver is needed for each database that must be accessed. It supports SQL Server v6. It handles the SQL request and converts it into a request that the individual database system understands.
It uses a hierarchical object model to allow applications to programmatically microsoft office access 2007 ole db provider free, retrieve, update and delete data from sources supported by OLE DB.
ADO consists of a series of hierarchical COM-based objects and collections, an object that acts as a container of many other objects. ADO is made up of nine objects and four collections. It is built around Microsoft. Though sometimes seen as an evolutionary step up from ADO, some fundamental structural microoft were made by Microsoft. NET runs through a. The object structure is no longer built around ofice Recordset object. Instead a Dataset object is used to contain data gathered from multiple sources.
This is transparent to the programmer. Conceptually, pffice Dataset object can be seen as a small in-memory relational database in its own right that allows for manipulation of data microsoft office access 2007 ole db provider free any direction. In order to propagate changes back into the database, a DataAdapter object is used that transfers data from between the data source and the DataSet object.
Cursors were also deprecated in ADO. NET, being replaced with a DataReader object, which is used to efficiently process a large list of results one record at microsoft office access 2007 ole db provider free time without storing them. MDAC is a continually evolving component framework. As such, there have been several components that продолжить чтение previously part of it but have since been deprecated or removed entirely from the framework.
Jet also provided support for security, referential integritytransaction processing jicrosoft, indexingrecord and page locking, and data replication.
In later versions of Перейти на источник, the engine was extended to run SQL queries, store character data in Unicode format, create viewsand allowed bi-directional replication with the Microsoft office access 2007 ole db provider free SQL Server.
There were three modules to Jet. It was basically an object-oriented data language used by Providwr Basic and Visual Basic application developers to access Jet. After MDAC 2. Features that were not supported were:. Remote Data Services RDS allowed the retrieval of a set of data from the server, which the client then altered in some way and then sent back to the server microsoft office access 2007 ole db provider free further processing.
It has not actually been deprecated but has been removed from later versions of MDAC, though Microsoft does providrr it as a downloadable component and will support it on their bit operating provixer. They are:. Microsoft has released several versions of MDAC over time. The distribution method has varied and the feature-set is different for each version. MDAC 1. It was released with Microsoft Internet Explorer 4. There ooe five versions of MDAC 1. This version of MDAC had a security flaw that made it vulnerable to an escalated privileges attack.
It also allowed the user to gain unauthorized access to secured, non-published files on the IIS system [38]. MDAC 2. It also had included many updates to the microsoft office access 2007 ole db provider free product, [36] including a security feature added to the RDS which prevented it from being used maliciously an IIS server. The components that microsoft office access 2007 ole db provider free included with 2. This version had security vulnerabilities whereby an unchecked buffer could allow an elevated privileges attack.
This was found some time later and it affected MDAC 2. They were also distributed through Microsoft’s website. Three service packs were released. The components included with 2. Several microsoft office access 2007 ole db provider free were found in this version of MDAC. This was later fixed. A security vulnerability also existed later fixed whereby an unchecked buffer was found in the SQL Server Driver.
This flaw was introduced in MDAC 2. Instead, these could be installed manually. Revision installed Free version 2. A refresh release offive issued in April through the release of Windows XP and through Microsoft’s website. Version 2. Hebrew and Arabic were only available through Windows XP. There were several known issues: [49] MDAC 2. Kennedywho identified that the change was actually made in MDAC 2. They were unimpressed that a fundamental functional change to the default behaviour microsfot Net-Lib occurred without more than a passing mention in an unrelated document.
It did not introduce any new features to the product but fixed a number of bugs and security issues — a reg file automates changes to the registry was removed that made the server run in an “unsafe” mode whereby the RDS could be exploited to gain unauthorized access to the system [58] and a new restriction was microsott on the length of the Shape query string. MDAC is now an official component of the Microsoft’s operating system, though they will be providing ongoing bug and security fixes to previously released versions of the web-distributable version.
It was formed to be independent of MDAC, which is now reliant on the state the operating system is in — a developer now links to this library and avoids situations where an update of the operating system which updates MDAC breaks applications built to a different version of MDAC. There are two ways of checking the version of MDAC that is installed on a computer.
