*Urgent* Need reference for DFD & ERD diagram
Posted on 2009-04-27
I am currently working on my assignment.
Can anyone give me reference to similar diagrams? DFD & ERD
Case Study 1
Projects, Inc. is an engineering firm with approximately 500 engineers of different types. The company keeps records on all employees, their skills, projects assigned and departments worked in. New employees are hired by the personnel manager based on data in an application form and evaluations collected from other managers who interview the job candidates. Prospective employees may apply anytime and these applications are kept in an applicant file.
Engineering managers notify the personnel manager when a job opens and list the characteristics necessary to be eligible for the job. The personnel manager compares the qualifications of the available pool of applicants (in the applicant file) with the characteristics of an open job and then schedules interviews between the manager in charge of the open position and the three best candidates from the pool.
After receiving evaluation on each interview from the manager, the personnel manager makes the hiring decision based upon the evaluations and applications of the candidates and the characteristics of the job, and then notifies the interviewees and the manager about the decision.
Applications of rejected applicants are retained for one year, after which time the application is purged. The personnel manager goes through the files each month to purge applications over one year old. When hired, a new engineer completes a nondisclosure agreement, which is filed with other information about the employee.
Draw a context and level 0 data flow diagram to represent the narrative. Please state your assumptions clearly.
Case Study 3
Draw an ERD diagram for the following:
MDIS, a private university, has several faculties and each faculty is headed by a Head of Faculty (HOF). A team of lecturers are assigned to each faculty and each lecturer may teach one or more courses. Each faculty offers several courses, for example, the computer science faculty offers courses in software engineering, human computer interaction, project management etc. The lecturers are able to check on their course schedules published by the faculty 2 weeks before the semester commences.
