Working with Data in Motion: Data in Transit vs Data at Rest, Extract Transform Load.

Updated November 3, 2026

1. Data in Transit vs Data at Rest (Apprentice): Stored data is at rest, and data moving between places, such as over a network or from a query, is in transit.
2. Extract Transform Load (Apprentice): ETL (Extract, Transform, Load) takes data from a source, reshapes it in a series of small steps, and stores it at a destination.
