Question

Need help writing a project, FAU has too many legacy systems that are getting difficult to maintain independently. OIT has decided to build a customized system to manage course, student, and faculty information to reduce costs and increase efficiency in the long run. OIT needs your help in creating this new and customized system. Your task is to create an application to process course, student, and faculty data that have been exported into text files and implement features important to FAU. The information below describes: • Data contained in the relevant text files • Functionality that you are required to implement for OIT • Optional functionality that you may choose to implement for OIT • Additional details to help understand aspects of OIT Contents of the relevant data files: • Faculty.txt contains information about faculty currently employed at FAU: Faculty ID, First Name, Last Name, Hire Date, Title, Salary, Street, City, State, Zip Code, Phone, Email, Department ID • Students.txt contains information about students currently enrolled at FAU: Student ID, First Name, Last Name, Street, City, State, Zip Code, Phone, Email, Major ID, Expected Graduation Date • Schedule.txt contains information about course schedules each term: Course ID, CRN, Title, Term, Faculty ID, Room, Capacity, Credit Hours • CourseRoster.txt contains information about students enrolled in each course at FAU: CRN, Student ID, Grade • Department.txt contains information about the different academic departments on campus at FAU: Department ID, Department Name • Major.txt contains information about the available majors in the different departments at FAU: Major ID, Major Name, Department ID Required functionality: At a minimum, your program should allow users to perform the following actions. You will lose points if you do not allow users to complete these actions: • (10pts) Lists of objects storing data from files listed above • (5pts) Menu with user options • (10pts) View student information for a single student • (10pts) View course schedule • (10pts) Create a new student • (10pts) Create a new course • (15pts) Print list of courses taken by a student • (15pts) Add a student to a course ISM 3230 Group Project – Requirements Spring 2016 2 Optional functionality: You may complete any or all of the components below for additional points: • (10pts) View faculty information for a single faculty member • (10pts) View list of courses taught by a faculty member • (10pts) Print list of students and grades for a course • (10pts) Create a new faculty member • (15pts) Edit information for an existing student • (15pts) Edit information for an existing faculty member • (15pts) Change a student’s grade in a specific course • (5pts) Calculate GPA for all students across all sections • (5pts) Calculate GPA for a specific student • (5pts) Calculate GPA for a specific course section • Logic to prevent errors o View list of courses taken by a student § (3pts) Student must exist o View list of courses taught by a faculty member § (3pts) Faculty member must exist o Create a new student § (3pts) Student must not already exist § (3pts) Student’s major must exist § (3pts) Email address must be unique and have @my.fau.edu § (4pts) Graduation Date must be valid and in the future (month/year) o Create a new course § (3pts) Course section (CRN) must not already exist § (3pts) Faculty teaching section must already exist o Add a student to a course § (4pts) A seat must still be available in the course o Create a new faculty member § (3pts) Faculty member must not already exist § (3pts) Faculty must belong to an existing department § (3pts) Email address must be unique and have @fau.edu o Edit information for an existing student § (3pts) If change major, major must exist § (3pts) If change email address, must be unique and have @my.fau.edu § (2pts) Cannot change ZNumber o Edit information for an existing faculty member § (3pts) If change department, department must exist § (3pts) If change email address, must be unique and have @fau.edu § (2pts) Cannot change ZNumber o Change a student’s grade in a specific course § (3pts) Grade must be a valid grade
