Q1. Use the below Scenario to draw the context and level-0 data flow diagrams that represent the video rental system. (30 points for context diagram, and 70 points for level-0 diagram)

Note: Make sure you include all the appropriate external entities, Processes, Data Stores, and Data Flows. Customer and manager are dealing with a video rental store system.

Every time the customer requests to rent a video, he/she needs to enter this request to the system, and the system stores the rental information in the rental data store after it checks for this video in the video library data store. Based on the customer’s request the system issues the bill information to the customer. The customer contacts the system once more to return the video, where the video returned information is sent to the video library and the rental data stores. In this case the customer receives a return receipt. A rental report is generated from the video library and rental data stores and is sent to the manger to show summary of rentals.

1. Draw two separate demand and supply diagrams to represent the beer market – one for Canada and one for Colorado. Be sure to label your graph properly (title, axes, curves, equilibrium, etc.) – your graph should be stand-alone which means a reader can easily interpret your graph. Show how the legalization of marijuana in each location has impacted the market for beer. Make sure you clearly indicate which curve shifts and compare the old equilibrium to the new one.*...
