How deeply does Think Like a CTO cover data warehouse?

Defines the warehouse’s purpose and contrasts it with data lakes, without detailing implementation.

Data warehouse

A data warehouse is a database optimized for analytical queries, reporting, and business intelligence over consolidated datasets.

A data warehouse is a database designed primarily for analytics and business intelligence. It houses large datasets arranged to make reporting and year-over-year analysis easier. section 8.5.1

Unlike a data lake, which can stage large volumes of varied files for backup or future analysis, a warehouse is organized for analytical queries and reports. Separating reporting workloads from customer-facing databases can also help prevent heavy reports from disrupting a website. section 8.5.1

Quarter-end reporting

A CFO’s large quarter-end sales report could affect a customer-facing website if both rely on one database. Separate databases for the areas they serve, with data replicated where needed, help avoid that conflict. section 8.5.1
