Creating a Rich Text Field in Database

Hello,

I’m quite a beginner in using databases. I want to create a project page on my website.
Each project will be a row in my project database table.
Everything fine so far, but how can I implement rich text ? I want some description field with bold, headers etc.
Is there a way to format that and save it in a db field ? Or there is an other trick to do it ?

By the way I was reading the topic about headless cms (strapi/directus), is this something I should look into ?

Thanks,

Matthias
