HW16: Chapter 16

Ex. 9.8
Briefly describe the three main types of software maintenance. Why is it sometimes difficult to distinguish between them?
  • Repairs - when software developers have to go back into their software and make changes to fix and bugs or faults that were found post release.
  • Environmental - if software developers have to go and make changes that have to do with the environment that the software runs on. Maybe the software was originally built to run on one software but now it needs to be run on a different one. Environmental changes to the software can cause bugs/faults to arise which could make this part of the first type of maintenance.
  • Functionality - When developers go back into the software to add more functionality to the software or add a new feature. The functionality can cause unforeseen faults/bugs to arise as well which also goes back to the first type of maintenance. 
Ex. 9.10
Do software engineers have a professional responsibility to develop code that can be easily maintained even if their employer does not explicitly request it?

As a professional? Yes, I think it would be their responsibility to do this. If the developer made code that was hard to maintain they would only be making their life harder and creating more work for themselves in the future.

Ex 5.3.  You have been asked to develop a system that will help with planning large-scale events and parties such as weddings, graduation celebrations, and birthday parties. Using an activity diagram, model the process context for such a system that shows the activities involved in planning a party (booking a venue, organizing invitations, etc.) and the system elements that might be used at each stage. Ex 5.5. Develop a sequence diagram showing the interactions involved when a student registers for a course in a university. Courses may have limited enrollment, so the registration process must include checks that places are available. Assume that the student accesses an electronic course catalog to find out about available courses. Ex 5.7. Based on your experience with a bank ATM, draw an activity diagram that models the data processing involved when a customer withdraws cash from the machine. Ex 5.8. Draw a sequence diagram for the same system. Explain why you mi...

Ex 11.4.  What is the common characteristic of all architectural styles that are geared to supporting software fault tolerance? Redundant and diverse are the characteristics of all architectural styles that are geared to supporting software fault tolerance.  Ex   11.7.  It has been suggested that the control software for a radiation therapy machine, used to treat patients with cancer, should be implemented using N-version programming. Comment on whether or not you think this is a good suggestion. I think that this is a good suggestion to have the control software implemented using N-version programming. I think this because radiation therapy is a very serious matter and this software can be the reason this person lives or dies. So it would definitely be beneficial to have multiple checks  of the software to make sure that the patient always gets the correct amount of radiation.  Ex   11.9.  Explain why you should explicitly handle all ...

HW6: Chapter 4

Ex 4.5  Using the technique suggested here, where natural language descriptions are presented in a standard format, write plausible user requirements for the following functions: 1. An unattended petrol (gas) pump system that includes a credit card reader. The customer swipes the card through the reader, then specifies the amount of fuel required. The fuel is delivered and the customer’s account debited. Function: Give gas to customer, accept and charge the customer's credit card, and print a receipt.   Description:  The customer swipes the card through the reader, then specifies the amount of fuel required. The fuel is delivered and the customer’s account debited. Inputs: Amount of gas that the customer wants and the customer's credit card information Source: credit card machine/reader and either screen where the amount of gas the customer wants is inputted or i guess the amount of gas is determined when the customer re-racks the gas nozzle. Outputs: amount of g...
