For the next 8 weeks - I challenge myself to:

Each Week's Challenge and their Solutions

For Week Two: Danny's Pizza Runner Challenge

In this case study, Danny own his own pizza store. Danny started by recruiting “runners” to deliver fresh pizza from Pizza Runner Headquarters (otherwise known as Danny’s house).

He has prepared for us an entity relationship diagram of his database design but requires further assistance to clean his data and apply some basic calculations so he can better direct his runners and optimise Pizza Runner’s operations.
