In computing, Microsoft's ActiveX Data Objects (ADO) comprises a set of Component Object Model (COM) objects for accessing data sources. A part of MDAC (Microsoft Data Access Components), it provides a middleware layer between programming languages and OLE DB (a means of accessing data stores, whether databases or not, in a uniform manner).
ADO consists of a series of hierarchical COM-based objects and collections, an object that acts as a container of many other objects. A programmer can directly access ADO objects to manipulate data, or can send an SQL query to the database via several ADO mechanisms. ADO is made up of nine objects and four collections. The collections are:
As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
ADO.NET is a data access technology from the Microsoft.NET Framework that provides communication between relational and non-relational systems through a common set of components. [1] ADO.NET is a set of computer software components that programmers can use to access data and data services from a database.
This provider translates ADO.NET method calls into ODBC function calls. Programmers usually use such a bridge when a given database lacks an ADO.NET provider, but is accessible through an ODBC driver. Microsoft ships one as part of the MDAC system component bundle, together with other database drivers, to simplify development in C#. Third ...
ADOdb is a database abstraction library for PHP, originally based on the same concept as Microsoft's ActiveX Data Objects. It allows developers to write applications in a consistent way regardless of the underlying database system storing the information.
The native UI Automation API (provider) is included as part of the Windows Vista and Windows Server 2008 SDK and is also distributed with the .NET Framework. UIA is available out of the box in Windows 7 as a part of Windows Automation API 3.0 and as a separate download for Windows XP, Windows Vista, and Windows Server 2003 and 2008. [4]
