Computer-implemented method for providing a data consistency between a first data source and at least a second data source in a data engineering system

Abstract

A method for providing data consistency between data sources includes providing first data, detecting a change information for the first data, providing a first version information of the detected change information, validating the change information, wherein a policy information contains at least a consistency rule executed on a common information model to decide about a consistent state of the first data defining whether the change information can be applied to the first data; updating the first version information to a second version information while confirming and repairing the detected data inconsistency of the change information, and supplying the change information with the version information as a production projection to at least a client engineering application.
