Hi Everyone

Got this LLD question in one of the interviews:
Question: Design a dashboard of restaurant chain.
Clarifying questions:

1. What is expected to be shown on the dashboard?
   A. Number of customers visiting a particular restaurant branch overtime (1 month, 1 year etc)
2. Do we also need to keep track of which user visits particular which branch over the time?
   A. Yes

Attempt :

1. I tried to make following entity classes:
   User

   • email
   • name
   • area code
     Restaurant
   • restaurant _id
   • restaurant code

2. For the database tried to write a simple repository class that would connect to mysql or any other relational DB
