Challenge Instructions

Objective

Define and explain a set of data models that facilitate menu item pricing determined by a combination of 3 factors: restaurant location, order type, and time of day.

Business Requirements

• Each restaurant Brand using the SALIDO platform has multiple Locations.
• Each Brand has various Menu Items that may be used by any of its Locations (e.g. Cafe Bangarang's FiDi and SoHo locations both sell a "Spicy Reuben").
• Each Brand has various Price Levels (e.g. Regular, Happy Hour) that may be used by any of its Locations.
• Each Menu Item may have a price assigned for each available Price Level (e.g. Spicy Reuben Prices: Regular: $4, Happy Hour: $2).
• Each Brand has various Order Types (e.g. Dine In, Take Out, Delivery) that may be used by any of its Locations.
• Each Location has one or more Day Parts, and every moment of the day must be covered by a Day Part (e.g. Breakfast: [02:00, 11:00), Lunch: [11:00, 17:00), Dinner: [17:00, 02:00)).
• Each Price Level is configured by correlating it with an Order Type and optional Day Part. These configurations are scoped to a Location.
  • e.g. For the FiDi location:
    • The "Regular" price level is applied if the order type is "Dine In"
    • The "Happy Hour" price level is applied if the order type is "Dine In" and the day part is "Dinner"
    • The "Delivery" price level is applied if the order type is "Delivery"
• The applicable Price Level for any given Menu Item is determined at the point of sale by assessing the Price Level configurations for the current Location. Here's the basic logic:
  • If the Menu Item has a price specified for the Price Level that correlates with both the current Order Type and Day Part, use that Price Level.
  • Else, if the Menu Item has a price specified for the Price Level that correlates with only the current Order Type, use that Price Level.
  • Otherwise, the Menu Item has no currently applicable Price Level and cannot be purchased.
