In this tutorial, you will learn about the different SQL database tables that make up an Episerver Commerce website and more importantly you will learn what each one does. When we work with Episerver and Episerver commerce, all the data we work with is stored within two back-end databases, one database for CMS data and one for commerce data. There are certain times when building a project where you encounter one of those annoying bugs that don't seem to make any sense. In a few situations after taking a peak in the database, I have managed to unblock myself. If you are trying to debug an Episerver Commerce related issue and you want to learn some tips and tricks to make it easier to figure out what's going on, read on 🔥🔥🔥
When we build projects with Episerver, you should never change the database scheme yourself, or, write custom code that talks to the database directly. Everything should always go via one of the Episerver APIs. Failing to stick to this rule will mean that when you upgrade your site it will likely break. Below I'm going to cover some of the most useful tables that have helped me to unblock myself over the years. The point of this article is to grow and expand over time, so if you want any extra knowledge about the Episerver database, please leave a comment or email me.
