Prep exercise week 4

As a preparation step for the upcoming Q&A, you need to work on the following exercise, which is based on the prep exercise of the previous week.

Exercise

Last week you updated your database to be normalized. Now that you have some more NoSQL knowledge, convert your database to a document-based database. Think about the following:

  • What are the collections?
  • What information will you embed in a document and which will you store normalised?

Discussion (Try to write answers to these questions in text, provide queries and commands when necessary)

  • What made you decide when to embed information? What assumptions did you make?
  • If you were given MySQL and MongoDB as choices to build the recipe's database at the beginning, which one would you choose and why?
