Week 3 Programming Assignment

Extend the weather program assigned last week to use a data model with a database backend.

• Use a migration to define a weather database.
• Manually go to weather.com and find the high and low temperatures for both April and May. Store this information in the database and retrieve it as needed.
• “Predict” the weather in May by (programmatically) adding 10 degrees to each high temperature for April
• Display the April data, the predicted May data, the actual May data and the difference between the predicted and actual May data.
• Perform the same operations for the low temperatures.
• Display
• the average high and low temperatures for each month, based on actual data, not predicted data
• the high for each month
• the low for each month
• the largest temperature difference in a single day for each month

Additional Requirements

• Use a minimum of three different views and corresponding methods in the controller.
• Add consistent navigation to your views so you can move from page to page clicking on links (or buttons). Navigation must be consistent across all pages.

Due date:

• May 29, 2008 (final deadline)

All work (programs 1, 2 and 3) must be completed and demonstrated to the instructor by May 29. No exceptions.

Turn in:

• Demonstrate your program to the instructor during lab.
• If your program does not pass the instructor’s test data, you will be asked to fix your program before it will be accepted.
