Data Warehousing (Redshift, BigQuery)

Part of the Cloud Computing Roadmap

In short

Databases optimized for large-scale analytical queries across huge datasets, rather than the fast, small transactional queries relational databases are built for — the destination for business intelligence and reporting workloads.

How to learn this

  1. 1Run a sample analytical query against a public dataset in a managed data warehouse.
  2. 2Learn the conceptual difference between OLTP (transactional) and OLAP (analytical) database design.
  3. 3Understand why a data warehouse is usually fed by an ETL/ELT pipeline, not written to directly by an app.
