MySQL is one of the most popular open-source databases in the world. It stores data in tables of rows and columns and you talk to it using SQL, the standard language for asking a database for exactly the data you want. If you have ever used WordPress, you have used a site backed by MySQL without knowing it.

Picture a well-organised filing cabinet where every drawer has a strict layout: a customers drawer where each card holds a name, email and signup date, an orders drawer linked to it. MySQL is that cabinet, and it keeps the structure consistent so the data stays reliable. It is a relational database, meaning tables connect to each other through shared keys, and you retrieve and combine them with SQL queries. To keep those queries fast as data grows, MySQL relies heavily on good indexing.

Its strengths are maturity and reach. It runs almost everywhere, it is well understood, and the community and hosting support around it are enormous. For workloads that do not fit neatly into tables, teams sometimes reach for a NoSQL option instead, but for ordinary structured data MySQL remains a dependable default.

The scale it handles surprises people. Facebook ran on MySQL for years, and most of the WordPress sites on the web, somewhere near 40 percent of all sites, sit on it too. You can start with a free copy on a cheap server and grow into a clustered setup that serves millions of users, all without switching database. That long runway is a big part of why so many teams reach for it on day one.

At TopDevs we use MySQL when a client needs a proven, low-fuss database for structured data, so their core records sit on a foundation that has been battle-tested for decades.
