Welcome

Ronald Bradford has spent 30 years building large-scale data systems, with deep specialization in MySQL and the open source relational database ecosystem. His work spans the full lifecycle of data — designing resilient, scalable architectures, shaping the data strategy that guides how organizations store and use information, and hardening that data against an evolving security landscape.

He approaches data architecture as both an engineering and a strategic discipline: not only how systems are built to scale and recover, but how data decisions align with long-term organizational goals. That perspective draws on decades of hands-on performance engineering, replication and high-availability design, and database security practices — increasingly relevant as AI workloads place new demands on data integrity, governance, and access control.

A long-standing contributor to the open source database community, Ronald is the author of the Effective MySQL book series, a recognized MySQL Subject Matter Expert, and a former Oracle ACE Director. He contributes to the VillageSQL community extensions for MySQL and has presented at conferences in 22 countries. His current work explores the intersection of databases and emerging AI — including running generative AI directly against database systems and the security implications that come with it.

Producing IQR and Outlier statistics with SQL

The interquartile range (IQR) measures the spread of the middle 50% of a distribution — the distance between the first quartile (Q1) and the third quartile (Q3). Combined with Tukey’s 1.

Producing Mode statistics with SQL

The mode is the value or values that appear most frequently in a dataset. Unlike the mean or median, it applies naturally to categorical and ordinal data — star ratings, product codes, survey responses — and reveals what is most common, not what is average.

Extending MySQL Capabilies with UDFs, Plugins and Components - Part 2

MySQL offers three different approaches to extending the SQL capabilities with the default product you download and install.
