Question :1. Use CASE tool Model to create an application class model that includes entity classes, user interface classes, boundary, and controller classes
2. Use CASE tool Model to create the System Architecture models. Use the 4+1 approach with the UML diagrams.
IT Online Training needs to develop an online service for IT training that includes scheduled as well as self-paced courses. The training service will be initially web-based but the architecture must have the option that different front-ends like applets, web services, or other designs can be used. The main function of the training site is to provide IT courses to its customers over the Internet.
