Class EntityRelationshipConsistencyTable

java.lang.Object
  it.unibo.cs.USI.tools.EntityRelationshipConsistencyTable

All Implemented Interfaces:

SemanticMappingConstants

public class EntityRelationshipConsistencyTable
extends java.lang.Object
implements SemanticMappingConstants

The table of consistency for entities and relationships. Part of the table is stored in form of rules (DISJOINTNESS and INCOMPATIBILITY for entities and DISJOINTNESS, INCOMPATIBILITY and INTERSECTION for relationships). For instance, if a pair of entities is incompatible, also relationships connecting them must be. The rest of the table is an actual table (a three dimensional array). Every entry contains an object that checks the cardinalities of the relationships.
