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).
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 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 ...
Since SQL Server data may reside on a remote server, and because SQL Server has its own query engine, it does not use the query engine of LINQ. Instead, the LINQ query is converted to a SQL query that is then sent to SQL Server for processing. Since SQL Server stores the data as relational data and LINQ works with data encapsulated in objects ...
If the browser encountered a page specifying an ActiveX control via an OBJECT tag (the OBJECT tag was added to the HTML 3.2 specification by Charlie Kindel, the Microsoft representative to the W3C at the time [8]) it would automatically download and install the control with little or no user intervention. This made the web "richer" but provoked ...
A database object is a structure for storing, managing and presenting application- or user-specific data in a database. Depending on the database management system (DBMS), many different types of database objects can exist. [1] [2] The following is a list of the most common types of database objects found in most relational databases (RDBMS):
ActiveX Data Objects ActiveX Data Objects (ADO) (both 32-bit and 64-bit versions) As well as DAO and ADO, developers can also use OLE DB and ODBC for developing native C/C++ programs for Access. [45] For ADPs and the direct manipulation of SQL Server data, ADO is required.
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.
