Eclipse Dictionaries play a key role in defining and accessing the information stored in data files. I‑Descriptors extend this capability by allowing you to manipulate data so it can be selected, calculated, or displayed in different ways without changing the underlying data. In this lab, you’ll build practical skills for creating and using I‑Descriptors to support more flexible data analysis and reporting.

By the end of this lab, attendees will be able to:

• Define and access data using Eclipse Dictionaries
• Manipulate data using I‑Descriptors to control how it is selected and displayed
• Create I‑Descriptors using @RECORD, FIELD, and CONCATENATE
