ODBC has become the de-facto standard for standards-based data access in both relational and non-relational database management systems DBMS. The ODBC standard enables maximum interoperability thereby enabling application developers to write a single application to access data sources from different vendors.
A data source is simply the source of the data. It can be a file, a particular database on a DBMS, or even a live data feed. In other cases, an ODBC driver may report that it supports certain functionality when it really doesn't. Doing so will help to avoid errors when you try to use the data connector to build metric sets and dashboards. As an example, suppose you have created an ODBC data connector successfully. When dragging one of the discovered tables to the canvas, you see an error such as:.
Error occurs when dragging table to canvas. To avoid this, edit the ODBC data connector. If you enable the Specify Driver Capabilities option but do not enable any of the capabilities, Dundas BI will perform all of the corresponding operations other than selecting all data in memory.

An ODBC driver acts as an interface between an application and a data source, which can be anything like a file, a relational or non-relational database, or a cloud application. A separate driver is required for each data source to be accessed. Subscribe for monthly digest to get special offers. Nor are driver writers expected to implement functionality not found in the underlying database.
An exception to this is that developers who write drivers that directly access file data such as data in an Xbase file are required to write a database engine that supports at least minimal SQL functionality.
Applications that use ODBC are responsible for any cross-database functionality. For example, ODBC is not a heterogeneous join engine, nor is it a distributed transaction processor. However, because it is DBMS-independent, it can be used to build such cross-database tools.
