اختيار مخازن البيانات حسب حمل العمل

في هذا الدرس

choose relational, NoSQL, cache, or search per workload.

الموضوعات المخطط لها

• Relational: transactions, joins, strong consistency; orders, payments, inventory.
• NoSQL (key-value, document): simple access patterns at large scale or flexible schema; carts, sessions, catalogs depending on needs.
• Cache: speeds repeated reads; never the source of truth.
• Search: full-text and faceted queries; fed from the source of truth.
• Polyglot costs operations; add a store only for a real need. One database for everything is also a mistake.
