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 ...
For VB [Visual Basic] 3.0 they basically had to tear it out of Access and graft it onto VB. That's why they've had all those Jet/ODBC problems in VB 3.0." Jet became more componentized when Access 2.0 was released because the Access ODBC developers used parts of the Jet code to produce the ODBC driver.
The application uses ODBC functions through an ODBC driver manager with which it is linked, and the driver passes the query to the DBMS. An ODBC driver can be thought of as analogous to a printer driver or other driver, providing a standard set of functions for the application to use, and implementing DBMS-specific functionality.
Microsoft Access is designed to scale to support more data and users by linking to multiple Access databases or using a back-end database like Microsoft SQL Server. With the latter design, the amount of data and users can scale to enterprise-level solutions. Microsoft Access's role in web development prior to version 2010 is limited.
DAO were originally called "VT Objects.: DAO 1.0 came up in November 1992 as part of Access 1.0. In version 3.5 it was able to bypass the Jet engine all together and directly access ODBC data sources, including Microsoft SQL Server and other enterprise database systems.
The following MDAC/Windows Data Access Components have been deprecated: 16-bit ODBC, Jet Database Engine and its Replication Objects (JRO), Remote Data Services (RDS), AppleTalk and Banyan Vines SQL Network Libraries, OLE DB Simple Provider (MSDAOSP), ODBC Setup, ODBC Cursor Engine and OLE DB Interface Remoting.
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 ...
PageAhead Software co-developed the first standards based ODBC driver with Microsoft in 1992, Simba.DLL. The first ODBC driver was included in Microsoft Windows 3.1, and has since been installed on over 30 million computers. [citation needed] ODBC is a widely used data access interface for relational database management systems RDBMS.
