What is an application?
A user application is any kind of application or system (e.g. a full blown Warehouse Management System) that offers some functionality to a user by means of a web based Graphical User Interface (GUI).
A service application runs in the background (i.e. it offers no GUI) and delivers a service that can be called by another application or service by means of a standardized interface - the logistics mall BUS.
A logistics mall app is a "small" user application that offers a dedicated functionality. Apps can be integrated into processes.
A mobile app is a logistics mall app that runs on mobile devices with android operating system.
Applications are offered at the Business AppStore by Independent Software Vendors (ISV)
