Fantastic article by Chidume Nnamdi 
We are just getting started with Strapi but we were disappointed to see that MongoDB will be dropped in V4 which is a shame as 99% of our projects use Mongo but we decided to focus on Postgres/Strapi instead and this article was very useful - thanks again.
Would be even better if this article also included deployment and managing data in production too as by sounds of it this can be a bit tricky at first.
Thanks!
