Critical Thinking Questions

A company's analysts query the production OLTP database directly for reports, causing slowdowns for operational users. Explain how implementing a data warehouse and BI architecture would solve this. What are the costs and trade-offs of building a separate analytical infrastructure?
Compare self-service BI (analysts create their own reports) with centralized BI (IT creates all reports). What are the benefits and risks of each approach? How can organizations get the best of both worlds?
An organization is choosing between Tableau, Power BI, and an open-source tool (Apache Superset). They have: limited budget, a small IT team, data in PostgreSQL, and analysts comfortable with SQL. Recommend a tool and justify.
