Model variables

Variables are task-independent data placeholders. A function or an event can store a value in a variable, and another function or event can extract and use this value in a later process step.

To use variables, you first must model them in a variable catalog.

A variable catalog is a model of the IE Data model type in which you model objects of the Cluster/Data model type. These objects represent the actual variables.

There must be exactly one variable catalog for each database.
