What is Lightning Data Service (LDS)?
Real World Scenario
You need Account Name on a component without writing Apex. You introduce LDS.
Expected Answer
• LDS provides declarative access to record data with caching and shared UI consistency
• lightning-record-form and lightning-record-view-form use LDS under the hood
• Wire adapters like getRecord fetch fields without custom Apex controllers
• LDS respects FLS and sharing automatically
• Prefer LDS over Apex for simple CRUD display to reduce server code and improve cache behavior

Complex aggregations, integrations, or operations LDS adapters do not support. LDS covers single-record and some list patterns.
Architect Perspective
LDS first on record pages—shows you avoid unnecessary Apex, a common junior mistake.
