The SAS Intelligence Platform architecture is designed to efficiently access large amounts of data, while simultaneously providing timely intelligence to a large number of users. The platform uses an n-tier architecture that enables you to distribute functionality across computer resources, so that each type of work is performed by the resources that are most suitable for the job.
You can easily scale the architecture to meet the demands of your workload. For a large company, the tiers can be installed across a multitude of machines with different operating systems. For prototyping, demonstrations, or very small enterprises, all of the tiers can be installed on a single machine.
Data sources store your enterprise data. All of your existing data assets can be used, whether your data is stored in third-party database management systems, SAS tables, or enterprise resource planning (ERP) system tables.
SAS servers perform SAS processing on your enterprise data. Several types of SAS servers are available to handle different workload types and processing intensities. The software distributes processing loads among server resources so that multiple client requests for information can be met without delay.
The middle tier enables users to access intelligence data and functionality via a web browser. This tier provides web-based interfaces for report creation and information distribution, while passing analysis and processing requests to the SAS servers.
The client tier provides users with desktop access to intelligence data and functionality through easy-to-use interfaces. For most information consumers, reporting and analysis tasks can be performed with just a web browser. For more advanced design and analysis tasks, SAS client software is installed on users' desktops. Some support for mobile devices is also provided.
