What key elements should every field entry in a data dictionary include?
Summary
Every entry needs a field name, plain definition, owner, valid choices, report impact, and correct input examples.
Every field entry in an accessible data dictionary should contain the field name, business definition, ownership, and valid choices. It must clearly state why the field exists and which business reports rely on its accuracy. Providing exact visual examples of correct and incorrect inputs removes remaining ambiguity during data entry. Additionally, including guidelines on when to update the field helps preserve database cleanliness over time. These elements together transform static technical entries into actionable operational instructions for all staff members.
