Teradata Mainframe Client Utilities update

Teradata has completed a major compiler conversion effort that should be completely transparent to customers, yet they are the main beneficiaries.  This article:

  • Provides some historical background and context,
  • Discusses the reasons we switched compilers,
  • Identifies certain behavioral changes that were unavoidable,
  • And, finally, answers a few technical questions related to the overall process.

The venerable IBM mainframe was the original client platform developed for the Teradata RDBMS via channel-attached connections way back in the 1980s. Although we now support a wide range of client platforms using network-attached connections, a significant segment of our customer base continues to use mainframe clients.

Creating an OData service using .NET Data Provider for Teradata

The Open Data Protocol (OData) is a protocol to share or exchange data over the web.  The protocol was developed by Microsoft in 2007 as part of the ADO .NET Data Services technology (a.k.a. Project Astoria) for creating and consuming data services using the Web. This protocol became widely used that Microsoft gave the protocol its own identification, named it OData and considered ADO.NET Data Services as the .NET implementation of OData.
