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 .
Arguably the most important interface for an OLE object. For example, it allows the container to inform the object of its site, initialize the object from data, to open and close it, to query and set the size of the object, to ask for notifications on the container's AdviseSink and to execute objects defined as "verbs" on the object. These ...
For example, Excel now exposes an extensive OLE Automation object model, which is the recommended method for communicating with Excel. The technique is, however, still in use, particularly for distribution of financial data. [4]
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).
If an application wishes to persist several data objects to a file, one way to do so would be to open an IStorage that represents the contents of that file and save each of the objects within a single IStream. One way to accomplish the latter is through the standard COM interface IPersistStream. OLE depends heavily on this model to embed ...
ActiveX is a deprecated software framework created by Microsoft that adapts its earlier Component Object Model (COM) and Object Linking and Embedding (OLE) technologies for content downloaded from a network, particularly from the World Wide Web. [1]

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.
