FAQ

Frequently Asked Questions

Do I need prior SQL experience?
No. The bootcamp starts from your very first SELECT and builds up. By the end you are writing window functions and tuning queries on 100k real orders.
Is this just PostgreSQL or general SQL?
Both. The fundamentals apply to any relational database, and the advanced modules lean on PostgreSQL-specific features like window functions, CTEs, partial indexes, partitioning, and stored procedures.
What dataset do I work with?
A 100k+ order Brazilian e-commerce dataset with real customer, order, payment, and review tables. You answer real business questions, not toy textbook problems.
Will this help in interviews?
Yes. Every module ends with the kind of question senior interviewers actually ask: join orderings, index selection, execution plans, and schema tradeoffs. You can walk into an interview able to defend your choices.
