Which MongoDB or MySQL for a local small business workflow web application?

Question

MongoDB

I'm going to write a web application for document management for our small production.
Orders, materials, warehouse.
Because no one drives, I want to master the newfangled nodejs. Everywhere there are a lot of examples of how a node works with MongoDB, and rarely with MySQL
I wondered if MongoDB would be suitable for my tasks, or is it still better to use a classic relational database?

Answer 1

With this formulation of the question, text files are also suitable for you. What are the database requirements?

Answer 2

First you need to figure out the entities that you will store. If there are many connections and chains between entities, but of course sql will be more needed.
Yes, you can use at least two of these databases, then how fantasy will play and design data storage.

Answer 3

Store data in text files?
I have 1-2 thousand orders per year.
+ base of designs for 2-4 thousand.
Plus changelogs...etc.
Basically, not much. But I can't believe that it's real to store in files.
As for connections, there won't be many connections.
I'll probably stick with MySQL
