Assignment: Internet Commerce

Each day, consumers spend around a billion dollars shopping online. Many companies host their own Internet commerce site or sell products through a storefront with an online retail site.

In this Application, you will identify an internet commerce site, investigate how it works, and create an activity diagram flow chart showing how the user and system interact in a typical user session and what services and protocols support that process.

First, choose an Internet commerce site to analyze. Though not required, the ideal site is one where you already have a user account and have previously shopped and purchased online using your current web browser.

Second, analyze the site from a user perspective. Include how to log in, how to search for products, and how to make a purchase. Also assess which aspects are specific to the individual user and which aspects are the same for all users.

Third, analyze the site from a technical perspective. Look at the browser source code to see what scripts are called. Determine whether they are run server-side or client-side. Check your browser cookies to find what information is stored directly in your browser. Research how the site handles sessions.

Based on your analysis, create an activity diagram flow chart showing what the user does and what the system does. Begin with the user going to the site to login, and finish with a completed purchase.

In addition, to your activity diagram flow chart, respond to the following questions. Your response to each question should be at least a full paragraph.

What information is stored on the users machine to facilitate the session? How is it stored? Why is this stored locally?

What information is stored on the internet commerce server? Why is this stored centrally?

How is information exchanged between the user and the Internet commerce server secured? Explain how you know.

List all protocols and scripts involved in the Internet commerce transaction. Explain how each is utilized.
