Web servers are programs that run on a server-tier computer and manage traffic by sending and receiving Web pages to and from clients. A commerce server is an application program that runs on a server-tier computer. Typical commerce server functions are to obtain product data from a database, manage the items in a shopping cart, and coordinate the checkout process. When a request comes to the server, the Web server examines it and sends it to the proper program for processing. Thus, the Web server passes e-commerce traffic to the commerce server. It passes requests for other applications to those applications.

The guidelines are wording, organization, length, selection, and highlighting. Following is each specification in more detail.

Wording
 • Each menu should have a meaningful title.
 • Command verbs should clearly and specifically describe operations.
 • Menu items should be displayed in mixed uppercase and lowercase letters and have a clear, unambiguous interpretation.

Organization
 • A consistent organizing principle should be used that relates to the tasks the intended users perform.

Length
 • The number of menu choices should not exceed the length of the screen.
 • Submenus should be used to break up exceedingly long menus.

Selection
 • Selection and entry methods should be consistent and reflect the size of the application and sophistication of the users.
 • How the user is to select each option and the consequences of each option should be clear.

Highlighting
 • Highlighting should be minimized and used only to convey selected options or unavailable options.
