Data Transformation Engine Type Designer Reference Guide

Chapter 1 - Introduction Hierarchy of a Type Tree
Imagine a type tree representing your house; see the My House.mtt type tree
below. There is a type for the entire house (House). A type for each room (Bath,
Bed, and so on), and types for the different furnishings in these rooms (Bed,
Chair, and so on).
Each type represents a complete object.
A house is made up of rooms. Inside these rooms are beds, chairs, couches, and
so on. You know this, but you cannot see it by looking at the classification
hierarchy view of the type tree. You must open one of the types in the group
window to see its components.
Data Composition
The type tree window does not display data composition. The group and category
windows do.
Note Data composition views are shown for group and category types only.
