Assignment No. 2
Consider the business process “exams_sessions_papers_aggregate”. The entities involved in the process are shown in above portion of ERD. The process calculates the information that can be sampled as follows:
“Totally 100 papers were conducted in exam center “VU001” in morning session in Fall 2013 exam”.
“Totally 110 papers were conducted in exam center “VU002” in evening session in Spring 2013 exam”.
“Totally 150 papers were conducted in exam center “VU001” in evening session in Fall 2013 exam”.
There are four steps of dimensional modeling. First step is to identify the business process. Consider the “exams_sessions_papers_aggregate” process described above. Apply the remaining steps of dimensional modeling to find out the fact and dimensional table(s).
