Question:
You have studied four steps which are involved in dimensional modeling. First step is to identify the business process. Consider the process “Player_performance” described above. Apply the remaining steps of dimensional modeling to find out the grain, facts and dimensions and then model a simplified star schema from it.
Note:
You need to run the three steps i.e. grain, facts and dimensions of dimension modeling at your own. You have to only draw the star schema in Solution file
