domains:
Business information management (BIM) – business information management is
responsible for maintaining the functionality of an information system. It is central to its
use. Based on this general definition of tasks, BIM supports the use of functions,

modifications.

maintaining application software and databases. As soon as modifications need to be
implemented for maintenance purposes, application management is responsible for
realizing and testing them. This also applies to the structure of databases.

software and data sets that constantly need to be available for use, can be operated.
