How Modern SQL Databases Come up with Algorithms that You Would Have Never Dreamed Of

Discover the power of SQL as a fourth-generation programming language in this 51-minute conference talk by Lukas Eder at Devoxx. Explore how modern cost-based optimization in relational databases like Oracle, SQL Server, and PostgreSQL fulfills the promise of a robust declarative programming model. Learn how these databases adapt to changing data without sacrificing performance, enabling complex SQL statements to run in sub-millisecond times against billion-row tables. Gain insights into how SQL outperforms hand-written data retrieval algorithms and why it excels as a language for business logic. Uncover the potential of SQL's logical approach and discover techniques to harness its power for efficient database development.
