Teradata Parallel Transporter: Leveraging Customer Focused New Features

Teradata Parallel Transporter is the premiere client load/unload tool, providing parallel extraction and loading of critical data.

A Day in the Life of a Unity Data Mover Job

Unity Data Mover (DM) is built to handle multiple requests to move objects concurrently. Understanding how DM processes these requests is benefitial to those looking to get the most out of their DM installations.

The easiest way to explain how DM handles work is to take a user request to move data and follow it through its life cycle. Along the way, we'll see how various user controlled settings affect the request and provide suggestions for how one might improve work throughput.

Large and Cheap: 3D Printing

I’ve written a few blogs on the future of 3D printing and its impact on manufacturing and data analytics in the future, or as Chris Anderson stated, “The long tail of things.”  But, up to now, 3D printing has been expensive and mostly for small objects.

How to Support "Resizing" for Viewpoint Portlets

Teradata Viewpoint 14.01 introduces a wider, more flexible layout, which better utilizes space on wide screen monitors, and gives the user more flexibility in controlling how much information is being displayed.


Extended Object Names in the .NET Data Provider

In Teradata Database Release 14.10 object names have been lengthened from 30 bytes of a Latin or KANJISJIS character set to 128 Unicode characters. This capability supports a richer set of characters to compose object names. While using a session character set that may contain limitations due to the supported set of characters, Unicode delimited identifiers are supported in all SQL text statements. Please see the SQL Data Types and Literals manual for information on Unicode delimited identifiers.

Displaying Tabular Data using the DataGrid and BigNumbers Widget

The following tutorial is a guide on how to implement the Viewpoint DataGrid and BigNumbers Widget.  In this example we will show how these widgets were incorporated into the SkewedSessions Portlet.  The actual source code can be found in the SkewedSessions Portlet supplied in PDK version 14.01.


Teradata Warehouse Miner 5.3.5 Express Edition available for download

Teradata Warehouse Miner provides an array of data profiling and mining functions ranging from data exploration and transformation to analytic model development and deployment that are performed directly in the Teradata Database. While many data mining solutions require analysts to extract data samples to build and run analytic models, Teradata Warehouse Miner allows you to analyze detailed data without moving it out of the data warehouse, thus streamlining the data mining process.

Teradata Warehouse Miner, and its derivative products Teradata Analytic Data Set (ADS) Generator, Teradata Data Set Builder for SAS and Teradata Profiler, can provide both a framework for the data mining process and a significant savings of time and resources in implementing the process.

Upgrading a Viewpoint 14.00 Portlet to 14.01

A portlet developed for Viewpoint 14.0 will, for the most part, work correctly on Viewpoint 14.01. The most impactful change to consider will be to make your portlet support horizontal resizing, and to make any code changes to use the latest versions of jQuery and jQuery UI included with Viewpoint 14.01.


Are AMP Worker Tasks used by FastExport in Response Mode?

I gave a presentation on AMP worker tasks at the Teradata User Group conference last week in Washington DC.   A question came from someone in the audience concerning FastExport jobs in response mode, and whether or not they were holding AMP worker tasks.  This post addresses that question.

How to Set up a UDF / XSP Debugging Environment

An integrated development environment is crucial to software developers for editing, building and debugging their program all within one environment. Therefore, setting up the right development environment is an important first task.

Here we set up a User-defined Functions (UDFs) / External Stored Procedures (XSPs) debugging environment used to debug typical UDF/XSPs. Eclipse Indigo is used as the IDE. A Teradata Express (TDExpress) VM is used as the running DBS.
