The basic idea of the Falcor API Style is to create a virtual JSON resource, as the central data model, which is actually used as a container. This virtual JSON resource is published under a URL address. Falcor then links data from various backends and data sources into this virtual JSON resource. The virtual JSON resource is all-encompassing and is designed to be extended over time. As a result, the virtual JSON resource is pretty big.
