## Purpose and Scope

Maps each Product Owner (PO) term to its professional IT term. PO language: English (`en`), domain `it`. It covers the words of the Day 52 assignment and the IT terms used in code.

## Rules

- The Domain Model, use cases and user stories use the PO term; the Operation
  Contract, Sequence Diagram, Design Class Diagram and ERD use the IT term.
- One IT term per PO term and one PO term per IT term; no synonyms.
- Rows are in ascending order of the PO term (case-insensitive, by the
  alphabet of the PO language), so a term is found without searching.
