A relationship between entity 1 data stored in a first system regarding an entity 1, and entity 2 data stored in a second system, different from the first system, regarding an entity 2 is stored in a relationship database. A relationship between the entity 1 data stored in the first system and entity 3 data stored in a third system, different from the first system and the second system, regarding an entity 3 is stored in the relationship database. A relationship between the entity 2 data and the entity 3 data is inferred by analyzing the relationship between the entity 1 data and the entity 2 data stored in the relationship database, and the relationship between the entity 1 data and the entity 3 data stored in the relationship database. The inferred relationship between the entity 2 data and the entity 3 data is stored in the relationship database. |
