6 00:00:19,801 --> 00:00:24,100 The **Data Ingestion** layer collects raw sensor streams and stores them in the staging area.

13 00:00:48,501 --> 00:00:52,300 If a record fails validation, it’s routed to the **dead‑letter queue**.

12 00:00:44,801 --> 00:00:48,500 **Component B – Validation Engine** Validates schema, timestamps, and checksum.

15 00:00:56,001 --> 00:01:00,400 All enriched records are persisted to the **processed** dataset.

5 00:00:15,601 --> 00:00:19,800 [Graphic appears] This diagram shows the three main layers: Data Ingestion, Processing, and Analytics.
