Online shopping (user to online buying)
Sample sites include typical retail sites where users buy books, clothes, or even cars. Site content can be relatively static, such as a parts catalog, or dynamic, where items are frequently added and deleted, such as for promotions and special discounts that come and go. Search traffic is heavier than on a publish/subscribe site, although the number of unique items sought is not as large. Data volatility is low. Transaction traffic is moderate to high, and almost always grows.
When users buy, security requirements become significant and include privacy, non-repudiation, integrity, authentication, and regulations. Shopping sites have more connections to legacy systems, such as fulfillment systems, than publish/subscribe sites, but generally less than the other site types. This is detailed inTable 2-2.
