ActiveX Data Objects (ADO) is a language-neutral object that is the basis for Microsoft's Universal Data Access strategy.
The Open Database Connectivity (ODBC) specification provides data access to, primarily, SQL-based databases. OLE DB is Microsoft's next generation following on from ODBC. Microsoft's plans for OLE DB go way beyond just providing access to relational databases. OLE DB providers will include spreadsheets, documents, graphics, e-mail, ...
ADO is a high-level interface to OLE DB. OLE DB includes a data provider that allows access to ODBC data sources; so ADO can use OLE DB's ODBC data provider to access a Mimer SQL data source in a very simple and straightforward manner.
Online applications can be built by using ADO on the server to deliver dynamic content through the World Wide Web. Through this mechanism, any client platform supporting a modern Web browser can access these applications, allowing users of Windows PCs, Macs, UNIX workstations and web-devices to simply connect to the application.
