fter a system has been built and tested, it is ready for installation. This is often a complex, difficult process that involves a certain amount of risk. Quite often, there are conflicting constraints, including costs, customer and employee relations, and logistic complexity. Phasing in a new system while phasing out the old system can be done in a variety of ways, each of which represents trade-offs between cost, complexity, and risk. Choosing the correct approach is crucial for successful installation. Based on the On the Spot Courier Services  perform the following tasks:

1. Use the Violet UML editor to create 1 Multilayer System Sequence Diagram (SSD) with data access classes for the On the Spot Courier Services. Follow the Multilayer SSD examples ). Take a screen shot, copy it into a Microsoft Word document. Save the Multilayer SSD Violet UML file, and send it to me into zipped folder.

2. What should be included in the Multilayer SSD with data access classes?

3. Describe how the Multilayer SSD with data access classes can aid development.

4. Describe how the Multilayer SSD with data access classes can aid implementation.

5. What should be included in a package diagram with dependency relationships? -Violet UML editor download link: https://sourceforge.net/projects/violet/

Note: Do not write introduction & conclusion. Answer in your own words. You can research on the Internet or books/journals & you can add additional references.

For number 1, you have to create 2 Multilayer System Sequence Diagram with data access classes for the On the Spot Courier Services.
