My Coding Bootcamp Odyssey - Week 5

So, on to the back-end (not of the pantomime horse 🐴) of a web application. This was all a bit of a mystery to me at first, although I had some insights.

Being at the older end of the Northcoders student age range (I only know the one Pokemon, the one that was my son's favourite!) I had come across relational databases using Microsoft Access back in the day. But knew nothing about NoSQL.

This week certainly enlightened me, and to be honest, I really loved it. Before joining Northcoders I had tinkered with HTML & CSS but the back-end was a complete mystery. This week really opened my eyes to the back end and I liked it - a lot. MVC really appealed to my sense of order and organisation and I can see how scalable and maintainable it could make large apps.

We'll see how the front-end block goes but at the moment back end is my beau!
