Why MySQL Remains Popular and Its Logical Architecture

In May 2022, the StackOverflow developer survey collected responses from over 70,000 developers, revealing that PostgreSQL (46.48%) narrowly edged out MySQL (45.68%) among professional developers, while MySQL still leads overall respondents (46.85% vs. 43.59%).

Despite the shift, MySQL remains the most popular open‑source relational database worldwide, ranking second on the DB‑Engines popularity list and powering countless internet services and cloud databases.

MySQL's logical architecture is described in three layers: the top layer handles client connections, authentication, and security; the middle layer performs query parsing, analysis, optimization, and implements cross‑engine features such as stored procedures, triggers, and views; the bottom layer is the storage‑engine layer, which abstracts data storage and retrieval via a unified API.

The article promotes the fourth edition of "High Performance MySQL," highlighting its expanded coverage of large‑scale, cloud‑native deployments, performance tuning, replication, high availability, and security best practices, positioning it as essential reading for developers, DBAs, and system engineers.

Additional promotional sections detail the book's new features, a giveaway of three copies, event rules, and a limited‑time half‑price discount, encouraging readers to acquire the book to deepen their understanding of MySQL's architecture and operational strategies.
