Abstract: A system comprising one or more computers implements a data retrieval interface. The data retrieval interface provides a unified schema definition language for data queries. Also the data retrieval interface implements a routing layer that applies default or custom prioritization parameters to select a data source from which to obtain data requested in a query from an application. The data retrieval interface may take into consideration connectivity, latency, costs, or other user specified parameters when selecting a data source and/or when selecting connection path to a selected data source to be used to obtain data in response to a query.
