Module #6 - Databases: Store and retrieve data with MySQL (Backend)

Have you ever thought about how your brain remembers things? It happens automatically for humans, but that's not so for computers. Any time you go to a website and you fill in some details, in for example a form, that information needs to be saved somewhere. This "somewhere" is called a database.

In this module you'll learn all about a fundamental part of any software application: how to (safely) store data, so that it can be used on-demand. You'll learn how to structure and group data so your apps know where to find and store the correct data.

Before you start

Before your first class you start you need to install the necessary software: MySQL. This differs depending on your operating system:

For Windows, download the MySQL Community Server
For Linux (Ubuntu), watch the following video: MySQL Installation on Linux (Ubuntu)
For MacOS, watch the following video: Installing MySQL on MacOS

Afterwards, read the following document to learn how to setup your database before your first class.

Learning goals

In this module you will get familiar with the complexity of storing data. By the end of it you have learned:

What the meaning is of a database entity
How to work with Structured Query Language (SQL)
Learn all about the relational model
Recognize the basic setup of a database
Know about MySQL as an example of a relational database system
Learn about NoSQL databases, with an emphasis on MongoDB

How to use this repository

Repository content

This repository consists of 3 essential parts:

README: this document contains all the required theory you need to understand while working on the homework. It contains not only the right resources to learn about the concepts, but also lectures done by HackYourFuture teachers. This is the first thing you should start with every week
MAKEME: this document contains the instructions for each week's homework. Start with the exercises rather quickly, so that you can ground the concepts you read about earlier.
LESSONPLAN: this document is meant for teachers as a reference. However, as a student don't be shy to take a look at it as well!

How to study

Let's say you are just starting out with the Databases module. This is what you do...

The week always starts on Wednesday. First thing you'll do is open the README.md for that week. For the first week of Databases, that would be Week1 Reading
You spend Wednesday and Thursday going over the resources and try to get a basic understanding of the concepts. In the meanwhile, you'll also implement any feedback you got on last week's homework (from the Node.js module)
On Friday you start with the homework, found in the MAKEME.md. For the first week of Databases, that would be Week1 Homework
You spend Friday and Saturday playing around with the exercises and write down any questions you might have
DEADLINE 1: You'll submit any questions you might have before Saturday 23.59, in the class channel
On Sunday you'll attend class. It'll be of the Q&A format, meaning that there will be no new material. Instead your questions shall be discussed and you can learn from others
You spend Monday and Tuesday finalizing your homework
DEADLINE 2: You submit your homework to the right channels (GitHub) before Tuesday 23.59. If you can't make it on time, please communicate it with your mentor
Start the new week by going back to point 1!

In summary:

To have a more detailed overview of the guidelines, please read this document or ask your mentor/class on Slack!
