Question 5:     Consider the E-R diagram in Figure 7-20. Based on this E-R diagram, answer the following questions:

Question 16: The owner of two pizza parlors located in adjacent towns wants to computerize and integrate sales transactions and inventory management within and between both stores. The point-of-sale component must be easy to use and flexible enough to accommodate a variety of pricing strategies and coupons. The inventory management, which will be linked to the point-of-sale component, must also be easy to use and fast. The systems at each store need to be linked so that sales and inventory levels can be determined instantly for each store and for both stores combined. The owner can allocate $40,000 for hardware and $20,000 for software and must have the new system operational in three months. Training must be short and easy. Briefly describe three alternative systems for this situation and explain how each would meet the requirements and constraints. Are the requirements and constraints realistic? Why or why not?

Question 17: Compare the alternative systems from Problem and Exercise 16 using the weighted approach demonstrated in Figure 7-19. Which system would you recommend? Why? Was the approach taken in this and Problem and Exercise 16 useful even for this relatively small system? Why or why not?

2)      Again, review the DFDs you developed for the Petrie’s Electronics case (or those given to you by your instructor). Use these DFDs to identify the attributes of each of the six entities listed in this case plus any additional entities identified in your answer to Question 1. Write an unambiguous definition for each attribute. Then, redraw Figure 7-1 by placing the six (and additional) entities in this case on the diagram along with their associated attributes.

3)      Using your answer to Question 2, designate which attribute or attributes form the identifier for each entity type. Explain why you chose each identifier. 

4)  Using your answer to Question 3, draw the relationships between entity types needed by the system. Remember, a relationship is needed only if the system wants data about associated entity instances. Give a meaningful name to each relationship. Specify cardinalities for each relationship and explain how you decided on each minimum and maximum cardinality on each end of each relationship. State any assumptions you made if the Petrie’s Electronics cases you have read so far and the answers to questions in these cases do not provide the evidence to justify the cardinalities you choose. Redraw your final E-R diagram in Microsoft Visio.

Chapter 10

Question 1:  Consider the reasons implementations fail. For at least three of these reasons, explain why this happens, if there is one (or more) type of implementation likely to minimize the occurrence, and if there is one (or more) type of installation more likely to induce failure for this reason.

Question 2: Two members of your project development team are disagreeing about the relative importance of training and documentation. Sam strongly believes that training is far more important because it will ensure the successful implementation of the information system and that the early usage is a positive experience. Pat encounters that the user documentation is far more important because its impact can help not only the current users, but also future users. Which do you think is right, and why?

Question 5: Due to advances in technology and widespread computer literacy, many organizations use e-learning extensively to train employees. If you were managing a system implementation and had to train on a limited budget, you may find yourself choosing between e-learning or conducting faceto- face training with a subset of users who would then train their departments (called train-the trainers). Which would you choose and why?

Question 6: Is it good or bad for corporations to rely on vendors for computing support? List arguments both for and against reliance on vendors as part of your answer.
