Detail description of service types
A detailed description of service types and capabilities of an information system can be given in the service allocation diagram. This includes
the interfaces of a block,
the interactions between the blocks,
the application systems supporting the block, and
business management functions that are supported by the block.
Zones, districts, building clusters, functional blocks, and capabilities can be connected to an IS service using the provides connection.
Input/Output connections can be drawn between IS elements and data elements to describe the information flows between the service types.
The various application system and IT function type objects can be assigned to the objects of the IT view via a connection of the supports type. If the city plan is interpreted as a development plan of a city, this connection provides information about which information system areas are 'populated' by which application systems. The supports connection is also available for use between IS elements and the function.
