Sometimes it is difficult to remember where you have used a given definition. In this demo you will learn how to find out what artifacts are associated with a given system definition (e.g. data set definition, language definition, translator). You will also practice re-associating a set of artifacts with a different definition in one easy operation. Note also that before archiving a definition you can use this function to ascertain what references would be broken by archiving, and then associate (re-factor) to a non-archived definition, thus ensuring referential integrity.
