As readers progress through the book, they will discover advanced concepts such as subqueries, common table expressions (CTEs), and window functions. They will also learn how to optimize their queries for better performance and how to use aggregate functions to summarize large datasets. The book concludes with a chapter on best practices for database design and development, emphasizing the importance of adhering to standards and conventions to ensure data consistency and integrity. Throughout the book, the author uses clear and concise language to make complex concepts accessible to beginners. The text is accompanied by numerous examples and exercises that allow readers to practice their skills and apply their knowledge in real-world scenarios. Additionally, the book includes tips and tricks for troubleshooting common issues and solving problems that may arise during the learning process.

По мере прохождения книги читателями будут открываться такие расширенные понятия, как подзапросы, общие табличные выражения (CTE) и оконные функции. Они также узнают, как оптимизировать свои запросы для повышения производительности и как использовать агрегатные функции для обобщения больших наборов данных. Книга завершается главой о передовых методах проектирования и разработки баз данных, в которой подчеркивается важность соблюдения стандартов и соглашений для обеспечения согласованности и целостности данных. На протяжении всей книги автор использует ясный и лаконичный язык, чтобы сделать сложные концепции доступными для начинающих.
