TD Module is interactive interface used to design various data processing tasks. 
Basicaly we have two types of tasks:

• tasks that take input perform some action and/or create some output,
• tasks that only perform some action withot inputs or outputs.

In an attempt to make it symple we categorised the first group of tasks acording to number of objects in the task.

Task objects are inputs, outputs (IO) and data processing services (DPS). 

AMS TD module has four DPS types:

• m2o ( one - many inputs, 1 output ),
• o2m ( one input, one - many outputs ),
• tvm ( time variant merge specific to datawarehousing ), and
• sql.

Combining DP services (chart on the far right ) will provide solutions for all batch application requirements, and transformation services like Lookup, Merge, Split, and Funnel.
