1. A college registrar keeps the registration records on students and their courses to take in the spread sheet with the column headings: LastName, FirstName, Phone, CourseTitle, CourseDate, CourseFee, and AmountPaid.
a. The registrar can keep the records in this way on the spreadsheet, but they will soon find inconveniences in handling the pets information. What kind of problems or issues may occur if they keep recording in this way? Think in terms of data entery, updating data, or deleting data.
b. To avoid the above problems, the registration records may need to be kept in separate "tables" in the Microsoft Access terms. How the tables should be set up to keep the registration information? You can write the table name and its contents such as TableName(fieldname1, fieldname2, etc).
c. For the tables you set up in b, assign or add appropriate primary keys and foreign keys for each table. Some table wouldn't need a foreign key. The primary key should be underlined, and foreign key in italic such as TableName(primarykeyname, fieldname1, fieldname2, foreignkeyname, etc).

5. The US Army has planned to develop an intelligent warfighting capability by providing continuous wireless communication capability to update the current battle situtaion and to deliver directions to the warfighters in realtime. In the consideration of its importance, the Army started as a huge sized program that contains numerous projects from tank redesign, communication equipment development, logistics system, to training all at once. The necessary technologies of the combined wireless communications are yet to be developed. Software development was not easy to define.
a. In this case, what kind of problems or risks would arise as the program proceeds?
b. As the whole program is not progressing as expected, the Army determined to cancel the Program. If the program is stopped, all previous efforts might be lost. To salvage the previous works and continuously pursue the development goal, the Army plans to contnue in a much smaller scale project. If you are in the project management team, describe how the team would develop the project management strategies.
