في هذا الدرس

use one shared vocabulary in talk and code.

الموضوعات المخطط لها

• The ubiquitous language is the vocabulary agreed with domain experts, used in meetings, docs, and class names.
• If the expert says "place an order" and the code says createRecord, translation errors follow.
• Build it with glossary sessions and by asking "what do you call this?".
• The same word can mean different things in different contexts (see MID-025).
• When the language changes, refactor the code names.
