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  PE 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 at 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.

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?

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
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?
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 face to face training with a subset of users who would then train their departments (called train the trainers). Which would you choose and why?
