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).
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: ActiveX Data Objects (ADO), OLE DB, and Open Database Connectivity (ODBC).
ActiveX Document is a Microsoft technology that allows users to view and edit Microsoft Word, Excel, and PDF documents inside web browsers. Active Messaging, later renamed Collaboration Data Objects; Active Server Pages (ASP) ActiveMovie, later renamed DirectShow; ActiveX Data Objects (ADO)
The aim is to return either basic data type or a Resordset object from all of the exposed api to have consistent interface, I do not want to expose custom objects (say 'Customer', 'Address', 'Item', 'Order', 'Invoice' etc). The client which receives this RecordsetC++ object should be able to iterate through rows as well as all the fields ...
It is commonly used by programmers to access and modify data stored in relational database systems, though it can also access data in non-relational data sources. ADO.NET is sometimes considered an evolution of ActiveX Data Objects (ADO) technology, but was changed so extensively that it can be considered an entirely new product.
ActiveX Document (also known as DocObject or DocObj [1]) is a Microsoft technology that allows users to view and edit Microsoft Word, Excel, and PDF documents inside web browsers. [2] It defines a set of Component Object Model coding contracts between hosting programs like Internet Explorer or Microsoft Office Binder [ 3 ] and hosted documents ...
The introduction of the mainframe-based relational database during the 1970s led to a proliferation of data access methods. Generally these systems operated together with a simple command processor that allowed users to type in English-like commands, and receive output. The best-known examples are SQL from IBM and QUEL from the Ingres project ...
In 1991, Microsoft introduced the Visual Basic Extension (VBX) technology with Visual Basic 1.0. A VBX is a packaged extension in the form of a dynamic-link library (DLL) that allows objects to be graphically placed in a form and manipulated by properties and methods. These were later adapted for use by other languages such as Visual C++.
