SAS Architecture

Client tier: This section allows you to view the portal and its content. Additionally, it comprises all the components you can use to view the portal and content. This also includes a web browser to interact with the portal over HTTP (HyperText Transfer Protocol) or HTTP/S (HyperText Transmission Protocol, Secure). These protocols make the SAS Information Delivery Portal user-friendly. You can place the portal anywhere on the network. Allowing users to access it from any internet connectivity. However, based on content, the client can also use one or more standard desktop applications. It can be Adobe Acrobat Reader or Microsoft Excel. You can use this application in the process of viewing content. Further, you can align the content with the servlets feature in the middle tier of the portal.

Moving ahead, when the web browser comes across such content that it does not know how to present it. It follows to look at the mime-type of content and tries to find a viewer that knows how to display it. Further, standard Web browser functionality diverges the stream of content to the suitable viewer for displaying. Finally, when the content comes under one of these applications, the user can process it locally or save it to disk.

Middle tier: This section hosts a centralized access point for enterprise information. Allowing access to content is processed by the components operating in this tier. When you separate business logic from display logic, it supports the logic of the middle tier. Also, with the help of centralized points, it becomes easier to enforce security rules, administer the portal and manage code changes.

The middle tier consists of the following functions:

SAS Information Delivery Portal: It comprises JSP, JavaBeans, Java servlets, and other classes and resources. These features allow you to access information stored in the enterprise directory to develop a customizable interface for the user.

Servlet Engine: You can also call the servlet engine as a servlet container. It manages the SAS Information Delivery Portal. The servlet engine hosts a run time environment. 

Web server: A web server hosts service for the servlet engine. Which further uses to host websites. You can access this using the portal.

Back Tier: The back tier is the third and last part of SAS architecture. The back tier is the section where the data and computation servers run. It comprises business objects. You can name it an enterprise directory server. The enterprise directory server balances metadata about content that is located throughout the enterprise.
