Review the Web Interaction Model
The Web Interaction Model provides you with one way of understanding how Web processes work together.
Web Interaction Model:
This model accounts not only for hardware, software, and networks, but also for the user's experience.
The Web Interaction Model is based on the idea of a series of layers operating dynamically, with each layer responding to
input and data from the other layers.

Web Interaction Model
Programmers are confronted by a series of challenges when they design interactive Web programs. Web interactions take place via Web browsers.
With browsers, consumers can whimsically navigate among the various stages of a dialog and can thus confuse the most sophisticated corporate Web sites.
In turn, Web services can fault in frustrating and inexplicable ways.
The quickening transition from Web scripts to Web services lends these problems immediacy.
To address this programming problem, we develop a foundational model of Web interactions and use it to formally describe two classes of errors.
The model suggests techniques for detecting both classes of errors. For one class we present an incrementally checked record type system, which effectively eliminates these errors.
For the other class, we introduce a dynamic safety check, which catches the mistakes relative to simple annotations of the programmers.
Limitations of the Web Interaction Model
You should keep in mind that there is overlap between the layers of the model. Each layer represents a discrete element of the Web.
Examine Multiple Elements
In some cases, elements support the layers above them, but in all cases, each layer is affected by the others.
This model makes distinctions among the elements of the Web, so you can consider your options for each element independently when
you are clarifying your Web site needs.
Your organization's business goals should drive the choices made at each layer.
When planning a Web site, examine multiple elements.
Consult all team members for input in their area of expertise.
End user satisfaction is affected by every component and layer of your Web site.
