Business glossary

  • Data basics

Definition

An agreed list of business terms and their definitions, owned by the business rather than IT.

Example

Illustrative entry: Active customer = a customer with at least one completed purchase in the last 90 days. Owner: Commercial Operations. This is an example rule, not a universal definition.

See how it works

  1. Agree the business term
  2. Specify calculation and exclusions
  3. Name an accountable owner
  4. Apply the definition consistently

Check your understanding

Common mistake: A glossary records agreed meanings. A data catalogue describes datasets and fields.

Why name an owner for a definition?

Show explanation

The owner can resolve disagreements and approve changes.

For your role

Choose your role to see what this term means in your work.

Why it matters

When teams define terms differently, reports disagree and trust falls.

Where it is used

Data governance programmes and reporting standards.
