Network information system
A network information system (also: network information system, short form NIS) is “an instrument for recording, managing, analyzing and outputting equipment data. These relate to the network topology, which must be given in a uniform frame of reference. " ( Lit .: Bill / Fritsch, 1991)
Supply and disposal companies work with this special form of geographic information system. The focus here is primarily on the geometric and graphic documentation of the line inventory. Therefore, they also fall into the category of operating and resource information systems ( facility management system ).
A network information system is a special version of a GI system (GIS).
Network information systems are used to manage gas and water networks, district heating networks, sewer networks, and electricity, data and telecommunications networks.
A network information system bundles the various graphic and alphanumeric information and keeps it ready for retrieval in one place.
Important properties of a network information system are:
- Integration of heterogeneous data in a homogeneous database structure
- Provision of a flexible database model for linking the data
- Administration and documentation of the network infrastructure and its components
- Definition of services and services
- Routing functions
- Cable and wire management
Network information systems continue to be used for planning network infrastructures, especially by planning and engineering offices.
