Salam,Homework 3 (analysis phase) has been graded.Attached you will find my comments about your analysis.Please note that our expectations from you as software engineers is much higher than this.What we were looking for was, something like the DFD decomposition in 6.pdf, the ERD of 2.pdf,The context diagram of 1.pdf or 2.pdf or 8.pdfand a mixture of state diagrams in 1.pdf and 2.pdf.P.S.: The weights for homework 3 are not yet decided so you don't have a real grade.--Regards,Darioush
