Abstract
A method, a system and a computer program product for resolving conflicts between data for database integration. Data is integrated from first and second data sources to produce integrated data, and the presence of a conflict is determined between data from the first data source and data from the second data source, where one or more sets of prioritized policies for resolving conflicts is associated with data of the first and second data sources. A policy is selected from the set of prioritized policies associated with the conflicted data, where the selected policy is appropriate to resolve the conflict and includes the greatest priority. The selected policy is applied to resolve the conflict and to produce a resulting data value for the integrated data.
