.NET Data Provider for Teradata

The .NET Data Provider for Teradata is an implementation of the Microsoft ADO.NET specification. It provides direct access to the Teradata Database and integrates with the DataSet. .NET Applications use the .NET Data Provider for Teradata to load data into the Teradata Database or retrieve data from the Teradata Database.  

The Teradata Developer Tools for Visual Studio is available from the Visual Studio Gallery. The release contains a query tool that enables queries to be composed and executed against a Teradata Database. Queries are composed using a custom editor window with intellisense capabilities.

Access External Data - Part 2 Add support for other data sources

The DbLink facility allows Teradata users to access data in external systems. However, as distributed, it only supports accessing data from external Oracle and Teradata systems.

In this article we will look at what is required to add support for other data sources. As it turns out, not much, just some basic Java programming abilities.

Access External Data - Part 1 The Table UDF

Many databases provide the ability for accessing external data via a mechanism via a SELECT query. Examples include Linked Tables in MS-Access and External Tables in Oracle. A similar capability will become available in Teradata 15, it will be known as Query Grid. However users of Teradata prior to 15 are out of luck.

Teradata has provided the foundation for accessing external data via a SELECT query ever since Table UDF's were added in or around Teradata 12. There is even reference in the UDF programmers manuals to just such a facility (but no actual code to show how to do it).

In this article, you can download a working facility I've called DbLink that you can setup and use to access data from external data sources without having to write your own UDF.
