Conceptual Models Conclusion

Limitations of tiered models

This module introduced you to conceptual models that attempt to explain how the Web works. The models provide a starting point for discussing the Web's complexities by breaking down the actions into discrete components. The Web Interaction Model is an effective method for depicting the full dynamics of a Web transaction. This model is used throughout this course, and the requirements for each layer will be fully detailed in future lessons.
By now you should be able to:
  1. Describe how Web technologies have changed the ways people use and obtain information
  2. Describe the components that make up the front-end/back-end model
  3. Describe how tiers model differences between hardware and technologies
  4. Explain the function of the Web Interaction Model
  5. Describe how the Web Interaction Model relates to other models

Next Gen Digital Workplace


In this module, you were introduced to the following glossary terms:
  1. ASP (Application Service Provider):An Application Service Provider (ASP) provides applications and related services over the Internet. Enterprises rent ASP software for a fee and the software is accessed remotely through a web browser and not installed on a company’s local drives. A multi-tenant version of this model is commonly known as Software-as-a-Service (SaaS).
  2. Clients: A client represents the host used to communicate with a remote or external server, where the server hosts application software which communicates with a database.
  3. Extranet: an intranet that can be partially accessed by authorized outside users, enabling businesses to exchange information over the Internet securely.
  4. Hyperlink: a link from a hypertext file or document to another location or file, typically activated by clicking on a highlighted word or image on the screen.
  5. Hypertext:a software system that links topics on the screen to related information and graphics, which are typically accessed by a point-and-click method.
  6. Intranet: a local or restricted communications network, especially a private network created using World Wide Web software.
  7. Personalization: Personalization, broadly known as customization, consists of tailoring a service or a product to accommodate specific individuals, sometimes tied to groups or segments of individuals.
  8. Search engine:a program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the World Wide Web.
  9. Server: a computer or computer program that manages access to a centralized resource or service in a network.
In the next module, you will learn about the first three layers of the Web Interaction Model: Signs and Metaphors, Information Architecture, and Software.
