《Rendimiento SQL explicado》 is the Spanish edition of Markus Winand’s 《SQL Performance Explained》, positioned as a “database optimization book for developers.” The page emphasizes that it is different from heavyweight database performance tomes: in around 200 pages, it covers the SQL performance knowledge developers actually need to understand. It feels more like a structured textbook or technical manual than a traditional online course.
Judging from the table of contents, the book focuses on the core issues behind SQL query performance, including B-Tree indexes, primary keys and composite keys, WHERE filtering, slow indexes caused by functions, bind variables, range queries, LIKE, composite indexes, partial indexes, NULL, complex conditions, joins, aggregation, Order By, Group By, Top-N queries, pagination, window functions, Insert/Delete/Update, and execution plans. The coverage is fairly systematic, making it especially useful for application developers who want to understand “why SQL is slow” and how to write queries that database optimizers can use more effectively.
In terms of delivery, the webpage only shows purchase options for the print book and PDF. There is no live class, recorded video, 1-on-1 coaching, homework review, learning community, or Q&A support. As a result, the learning experience mainly depends on self-study, and it is best suited to readers with some technical foundation who can practice in their own database environment.
Pricing is straightforward: print + PDF costs €34.95, paperback costs €29.95, and PDF costs €9.95. The page also mentions PayPal and free worldwide shipping. The PDF is inexpensive and offers strong value. It also states that users who have purchased the PDF can re-download the latest version, which is a plus for a technical book. The page does not mention any certification or completion certificate, so it is not suitable for learners who need a credential for job hunting or formal training proof.
The strengths are its clear positioning, solid table of contents, friendly pricing, Amazon.es five-star rating, and multiple reader testimonials. Markus Winand also has a clear background in SQL advocacy, writing, and consulting. The drawbacks are that this is not an interactive course and lacks teaching services, a practice system, and information about a Chinese version. For complete beginners, it may also be less intuitive than a video course.
It is suitable for backend developers, data developers, database application programmers, and anyone who wants to systematically strengthen their SQL performance fundamentals. The page does not provide enough information about access from China, and payment is only explicitly stated to support PayPal. Availability in mainland China will depend on network conditions and the user’s payment setup. If access or payment is inconvenient, alternatives include use-the-index-luke.com, modern-sql.com, official database documentation, or SQL optimization courses on Udemy and Coursera.
