Case Study #1: Weather Forecast Display - Strategy Design Pattern Utilize the Strategy Design Pattern to display the different types of displays Application requirements state that user should be able to view the weather forecast for 24 hours, 2 days, 7 days or 15 days. Weather forecast class will display the weather forecast details as per user requirement by choosing the appropriate method/algorithm for 24 Hours, 2 days, 7 days and 15 days. Case Study #2: Dashboard to display dataset in different charts

Consider the following description for a dashboard application to answer the following: 1. List of use-cases 2. Design Class diagram 3. What are the design patterns that should be utilized in the design class diagram? Dashboard Application - High-Level Description The dashboard enables user to select required dataset. Based on the selection of the user, the dataset can be displayed in in tabular format and different types of charts. User can filter the rows and columns of choice to plot/display the data in charts. Requirements/Features List User should be allowed: To select dataset. To visualize the data using different types of chart 1. Bar 2. Line 3. Pie 4. Doughnut To filter the data by rows (horizontal slicing) and columns (vertical slicing) To export the data into JSON/CSV format file.
