Until fairly recently, magazines and periodicals were available in printed versions only. Publishers are now offering an increasing number of periodicals in either the traditional printed version or in a digital format that can be downloaded over the Internet. Consider the processes involved in these two methods and:

a. Create a high-level data flow diagram describing the typical traditional methods of renewing a subscription via mail to the print version of a magazine.

b. Create another high-level data flow diagram describing the processes for renewing a subscription via the Internet to the digital format version of a magazine.

c. What, if any, are the essential differences between the two diagrams?

d. Based upon the data flow diagrams, which format is more efficient in renewing a magazine subscription? Do you think the same holds true from the perspective of the subscriber? What about from the perspective of the publisher?

e. What about receiving and reading the magazine? From your own perspective, what are the advantages and disadvantages of a magazine published in digital format versus the traditional print version?
