PowerExchange for SAS Architecture

PowerExchange for SAS Architecture

The central component of the architecture for PowerExchange for SAS is the Communication component, which is also known as the SPI Server. The SPI Server is a multithreaded TCP/IP listener service. It is installed on the machine that runs SAS, and handles requests from the Developer tool and the Data Integration Service.
When you use the Developer tool to import SAS data objects, the Client component requests the metadata from the SPI Server. The SPI Server starts an SPI session to retrieve the information from SAS and then passes this information to the Client component. When you save the SAS data objects, the Model Repository Service component saves them to the Model repository.
When you run a mapping that contains a SAS source or target, the Data Integration Service uses the Data Integration Service component to start a session with the SPI Server. The SPI Server accesses SAS data and passes it back to the Data Integration Service component for processing the data.
