Abstract: A system having databases that executes steps including receiving an identifier of a first entity, performing a first search of a database that returns an identifier of a second entity having a relationship with the first entity, performing a second search of a database that returns an identifier of a third entity that is a creditor of the second entity, and constructing in a storage device, a data structure that defines a path between the first entity and the third entity via the second entity. The system can include a processor and a memory with instructions. The instructions, when read by the processor, cause the system to perform methods described above.

Abstract: A method including receiving an identifier of a first entity, performing a first search of a database that returns an identifier of a second entity having a relationship with the first entity, performing a second search of a database that returns an identifier of a third entity that is a creditor of the second entity, and constructing in a storage device, a data structure that defines a path between the first entity and the third entity via the second entity. The method can be executed by an apparatus having a processor and a memory with instructions. The instructions, when read by the processor, cause the processor to perform the method described above.
