Cross-domain link determinations through cell fusion and supergraph processing

A system comprising:

• a processor;
• and
• a non-transitory machine-readable medium comprising instructions that, when executed by the processor, cause a computing system to:
• identify databases of different systems, wherein the databases comprise tables comprised of data elements stored in rows and columns;
• construct a supergraph that represents the data elements stored in the databases of the different systems, including by:
• constructing graphs for the tables in the databases of the different systems in which data elements of the tables are represented as nodes in the graphs;
• and
• merging the graphs constructed from the databases of the different systems into the supergraph, including by performing a cell fusion to merge multiple nodes from the graphs with an identical data element value into a fused node in the supergraph;
• and
• process the supergraph according to cross-domain linking criteria to determine cross-domain links for data stored in the databases of the different systems.
