• Data Lake: A vast pool of raw, unstructured data stored in its native format until it’s needed for use.
• Delta Lake: An open-source storage layer that brings reliability and ACID transactions to data lakes, unifying batch, and streaming data processing.
• Data Pipeline: A process that moves and transforms data from one system to another, often used to populate data warehouses and data lakes.
• Data Mesh: An architectural and organizational approach where data ownership and delivery are decentralized across domain-specific, cross-functional teams.
