Teradata recently launched their TBIO (Teradata Business Intelligence Optimizer) product.  Martin Willcox from Teradata has a little YouTube video in which he describes a bit more about the TBIO product.  You can watch it here: http://www.youtube.com/watch?v=_o-qVYRxwM0.  Basically, the Teradata Business Intelligence Optimizer has 3 components:

1. Teradata Schema Workbench

2. Teradata Aggregate Designer

3. Teradata OLAP Connector

Schema Workbench lets you define your OLAP schema within your Teradata database.  Aggregate Designer lets you build the aggregate join indexes so that queries on your OLAP schema run fast.  OLAP connector allows Microsoft Excel Pivot Tables to connect to your Teradata database using the MDX Query Language so you can do ad-hoc query and analysis on your data.  No data movement is required.  Everything is done within your Teradata database.
