Frequently Asked Questions
What kind of database does WordPress use?
WordPress uses MySQL (or MariaDB), which is a relational database. It stores all your posts, pages, comments, settings, and user accounts in structured tables.
Can a database slow down my website?
Yes. Over time, databases can accumulate overhead from revisions, spam, and transient data. Regular database optimisation, which your developer or a maintenance plan can handle, keeps things running smoothly.
Is my database backed up automatically?
It depends on your hosting provider and setup. Some hosts include daily backups, but you should verify this and ideally have an independent backup solution as well, just in case.
