Gateway Model Types(simplified view)

Data Source Model

Unmodified model of existing SAP Business Suite services

in a Gateway-internal representation

User-Centric Exposure Model

Consumable model, derived from a PSM and optimized for

an specific use case (mobile, web, embedded)

Public Solution Model

Service model that is adapted (reduced) for lightweight

consumption via Gateway
