replace joins with three techniques.

الموضوعات المخطط لها

• API composition: call each service and combine results in a gateway or backend-for-frontend; fine for small result sets.
• Events and local copies: keep a read-only copy of the fields you need, updated by events; it can be briefly stale.
• Denormalize at write time: store a snapshot, e.g. product name and price in the order line.
• Large reporting joins belong in a separate read model or analytics store.
• Accept that each choice trades freshness, coupling, and cost.
