SQL provides a set of useful functions, but they might not satisfy all of the particular requirements you have to process your data.

User-defined functions (UDFs) allow you to extend SQL by writing your own functions in the C/C++ programming languages, installing them on the database, and then using them like standard SQL functions.

Customers are currently leveraging Teradata's features such as User Defined Functions (UDFs) and External Stored Procedures (XSPs) to develop complex applications.

The aim of this set articles is to show the user how to use the Eclipse IDE to debug in a single-node, controlled, non-production environment:

• Java or C/C++ User Defined Functions (UDFs)
• Java or C/C++ External Stored Procedures (XSPs)

The audience for this set of articles ranges from Teradata associates within the R&D and Professional Services organizations to  Teradata Customer and Partner developers who want to debug a UDF/XSP running on their  DBS VM before installing it on a production system.
