GCP Cloud Digital Leader Practice Question

Which option accurately differentiates among a database, a data warehouse, and a data lake based on each system's primary purpose in an organization's data strategy?

  • Databases handle day-to-day transactional workloads on structured data, data warehouses store integrated historical data for analytical queries, and data lakes keep large volumes of raw or semi-structured data for future exploration.

  • Databases ingest streaming data in real time, data warehouses support high-throughput row-level updates, and data lakes keep strictly curated datasets with fixed schemas.

  • Data lakes are optimized for online transaction processing, databases store historical analytics data, and data warehouses ingest raw sensor files with no defined schema.

  • Data warehouses are designed primarily for low-cost storage of videos and images, databases generate batch reports, and data lakes power interactive dashboards for business users.
