Abstract: Suggested is a computer-implemented method for data management, in which method a service provided or to be provided by a service provider, such as the implementation of a customer order, is represented by electronic data on the basis of an information model, which defines a large number of different but related information objects (10, 12, 14, 16), by which the service can be represented. The method includes the generating of a large number of data records, which each represent one of the information objects. For at least some of the information objects, the data records each contain a time stamp, which represents the time of generation of the data record concerned. The method also includes the generating of several data records each representing a different version of the same information object, these data records differing from each other at least in their time stamp.

Abstract: A computer-implemented method for management of electronic data, comprises the steps: Writing of a data record into a first database (50), checking of the unchanged contents of this one data record on at least one predetermined condition and writing of the one data record into a second database (52) dependent on the fulfilling of the at least one predetermined condition.
