Abstract: A data management system includes a data reconciliation engine that identifies data sources that contain data records referencing a resource and determines whether each of the identified data sources is a creative data source or an additive data source. When all of the identified data sources are additive data sources, the reconciliation engine terminates a data reconciliation process. When all of the identified data sources are not additive data sources, the reconciliation engine finds a first creative data source from among the identified data sources, and initiates the data reconciliation process by merging data from the identified data sources including the first creative data source, one data source-by-one data source, into a reconciled data record.

Abstract: In one general aspect, a computer system can include instructions configured to store on a non-transitory computer-readable storage medium. The computer system can include a subgraph transformer configured to transform a plurality of subgraphs of a source graph into a plurality of transformed subgraphs, and configured to define a target graph that is a transformed version of the source graph based on the plurality of transformed subgraphs. The computer system can include a change detector configured to receive an indicator that a portion of the source graph has been changed, and a synchronization module configured to synchronize a portion of the target graph with the changed portion of the source graph.
