Acknowledgement
There are a few people who really deserve to be thanked for making this Project paper a success. Without their support as well as help this Project paper could never have been completed. I remember all of them with gratitude though. I can’t mention all of their names individually for the spatial limitation. I would like to express my deepest gratitude and appreciation to my Supervisor Prof. Dr. Mostafa Kamal Advisor, Daffodil institute of IT (DIIT) it would have been possible for me to complete this work without his help advice and suggestion. I would like to express my deepest gratitude to those people who helped me by spending their valuable time in questioner Project paper. I am also grateful to some of my friends. Who helped me to collect information from the websites of Aristopharma Ltd. I am grateful to God, who is almighty & all powerful without.
