Abstract: A server system provides one or more element applications configured to render document elements, including generating visualization data representations for generating the document elements, in particular on the basis of data obtained from one or more data sources; executing a graphical user interface for access by a user on one or more client computers, each client computer or user thereof being associated with a respective tenant of one or more tenants, wherein the client computers are communicably connected with the server system via one or more communication networks; wherein one or more document applications are provided for generating electronic documents upon request of a respective client computer or user thereof for being displayed and/or for printing purposes, the one or more document applications being executed on the one or more client computers and/or on one or more servers of the server system.

Abstract: A computer program product comprising computer-readable instructions that, when executed in a computer system including one or more computers, cause the computer system to generate or update a user interface of a software application, the computer program product including programmably interconnected objects, said objects including one or more model objects, one or more view objects, and one or more controller objects, wherein each model object is interconnected for data exchange with one or more view objects and/or with one or more controller objects; and each model object includes one or more sub-model objects including hierarchically structured data and representing a state of the user interface; and each view object is associated with at least one model object or at least one sub-model object and configured to generate the user interface or update the user interface in accordance with a change of the state.
