Data Transformation Engine Type Designer Reference Guide

Chapter 1 - Introduction Type Trees
Each circle icon in the type tree identifies a data type. The tree has a root type
and other types are connected to the tree through branches of the tree. The root
type is the base type from which all other types stem, representing the data
objects of all the types in the tree.
By default, the types are in alphabetical order, from top to bottom. The order of
new types is defined in the Value column of the Order subtypes Property. There
are four options: Ascending, Descending, Add First, and Add Last. The
following example illustrates the default Ascending order.
Viewing the data in the type tree shows the different kinds of data objects. The
type tree window does NOT show the layout or composition of the data. For
example, by looking at the tree, you cannot tell that a record consists of fields.
Data Content
The entire contents of your data must be defined. Define the input data so that
each data object of the source data is identified. Define the output data according
to your output specifications.
How specifically you define the data is up to you. For example, if there is a large
section of data that you want to process quickly, define it loosely as a chunk of
text.
In the Type Designer, the data content is not defined as the source data or target
data. Data input and output definitions are defined in the Map Designer. The Type
Designer simply contains the definition of your data.
