Figure 1. SchizConnect Architecture & Data Flow.

Figure 1

The SchizConnect architecture has the following 3 components: the federated data sources, the SchizConnect Mediator, and the SchizConnect.org web portal. After the user builds the query at the SchizConnect web portal, the query command is passed to the SchizConnect Mediator engine. The Mediator engine then relies on the SchizConnect domain model to translate the incoming query into source-specific schemas, then queries each data source directly and in parallel, using source-specific query mechanisms, languages, and variables. The returns from the sources are handled by the Mediator engine, which provides the SchizConnect web portal with a unified results table. The SchizConnect web portal then interacts with the user for further processing, including signing of data use agreements and data download.
