13. What is the purpose of DFD? What are the components of DFD?
Construct for the following system.
An on-line shopping system for XYZ provides many services and
benefits to its members and staffs. Currently, XYZ staffs
manually handle the purchasing information with the use of basic
office software, such as Microsoft Office Word and Excel. It may
results in having mistakes easily and the process is very
inconvenient. XYZ needs an online shopping system at their
intranet based on the requirements of users. XYZ online shopping
system has five key features:
(a) to provide the user friendly online shopping cart function to
member to replace hardcopy ordering form;
(b) to store inventory and sales information in database to
reduce the human mistakes, increase accuracy and enhance
the flexibility of information processing;
(c) to provide an efficient inventory system which can help the
XYZ staffs to gain enough information to update the
inventory;
(d) To be able to print invoices to members and print a set of
summary reports for XYZ’s internal usage;
(e) To design the system that is easy to maintain and upgrade.
