OLE DB providers are analogous to ODBC drivers, JDBC drivers, and ADO.NET data providers. OLE DB providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle, Microsoft SQL Server, Sybase ASE, and many others. It can also provide access to hierarchical data stores such as ...
OLE DB 2.1; the OLE DB Provider for ODBC, SQL Server and Oracle; JRO 2.1; a Jet driver; RDO. [41] This version had security vulnerabilities whereby an unchecked buffer could allow an elevated privileges attack. This was found some time later and it affected MDAC 2.1, 2.5 and 2.6 and was addressed in a later patch [42]
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.
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.
ADO.NET data providers are analogous to ODBC drivers, JDBC drivers, and OLE DB providers. ADO.NET providers can be created to access such simple data stores as a text file and spreadsheet, through to such complex databases as Oracle Database , Microsoft SQL Server , MySQL , PostgreSQL , SQLite , IBM Db2 , Sybase ASE , and many others.
Virtuoso is made up of client and server components. These components typically communicate with a local or remote Virtuoso server, which include: Virtuoso Drivers for ODBC, JDBC, ADO.NET and OLE DB; Conductor, a web-based database administration user interface; ISQL (Interactive SQL) and ISQO Utilities; Documentation and Tutorials; Samples
OLE 1.0, released in 1990, was an evolution of the original Dynamic Data Exchange (DDE) concept that Microsoft developed for earlier versions of Windows.While DDE was limited to transferring limited amounts of data between two running applications, OLE was capable of maintaining active links between two documents or even embedding one type of document within another.
An ODBC driver for SQL CE does not exist, nor is one planned. Native applications may use SQL CE via OLE DB. The latest, and last, release is SQL Server Compact 4.0. [1] In February 2013 SQL Server Compact Edition had been deprecated; no new versions or updates are planned, although Microsoft continued to support the product until July 2021. [3]
