MySQL
Overview
What MySQL is
MySQL is an open-source relational database management system first released in 1995 and now owned by Oracle. It organizes data into structured tables of rows and columns and uses SQL to insert, query, and update records. MySQL is known for being fast, stable, easy to set up, and supported by virtually every web host and cloud provider.
Where MySQL fits
MySQL powers a huge share of the web, including WordPress, which runs on it by default, along with countless e-commerce and SaaS applications. It is especially strong for read-heavy sites and straightforward transactional workloads. A related open-source fork, MariaDB, is largely compatible and is sometimes used as a drop-in replacement.
How an agency uses MySQL
MySQL is a dependable choice for backend development, full-stack builds, and app backends and APIs, particularly for content sites and stores where its ecosystem and hosting support shine. A team often combines it with Node.js or Python, adds Redis caching for speed, and secures access with a provider like Auth0. It also integrates cleanly into automation workflows.
