I have used SmartDraw 2010 and GanttSoft Project Manager 2.0 softwares to draw the SDLC models, DFD, ERD and Gantt Chart for this assignment. I have attached a CD which contains the soft copy of completed assignment and all the images, which is used for this assignment. This assignment has led me to learn a lot of subjects about system analysis.
