OLE DB (Object Linking and Embedding, Database, sometimes written as OLEDB or OLE-DB) is an API designed by Microsoft that allows accessing data from a variety of sources in a uniform manner. The API provides a set of interfaces implemented using the Component Object Model (COM); it is otherwise unrelated to OLE .
The Microsoft OLE DB Provider for ODBC, or MSDASQL, was an OLE DB provider for allowing ActiveX Data Objects access to databases via any ODBC driver. Microsoft supplied several OLE-DB providers (for the Indexing Service, Active Directory , Jet, SQL Server, Oracle ( MSDAORA [ 28 ] ) and Internet Publishing), however unless otherwise directed ...
The connection object is ADO's connection to a data store via OLE DB. The connection object stores information about the session and provides methods of connecting to the data store. As some data stores have different methods of establishing a connection, some methods may not be supported in the connection object for particular OLE DB provider.
In computing, a connection string is a string that specifies information about a data source and the means of connecting to it. It is passed in code to an underlying driver or provider in order to initiate the connection. Whilst commonly used for a database connection, the data source could also be a spreadsheet or text file.
For example this interface provides a way to access the container's window's device context, thereby enabling the embedded object to draw in the container's window. IOleUILinkContainer Contains the methods that the standard OLE dialog boxes that manage linked objects use to update linked objects in a container, or to query and change their sources.
An OLE DB-ODBC bridge consists of an OLE DB Provider which uses the services of an ODBC driver to connect to a target database. This provider translates OLE DB method calls into ODBC function calls. Programmers usually use such a bridge when a given database lacks an OLE DB provider, but is accessible through an ODBC driver.
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.
OLE DB for OLAP (Object Linking and Embedding Database for Online Analytical Processing abbreviated ODBO) is a Microsoft published specification and an industry standard for multi-dimensional data processing.
