Let V be a set real world entities, that admits a relational model. An attribute induces an equivalence relation on V and will be regarded as such. Let A* be the set of such equivalence relations and their refinements. Then the smallest sublattice L(A*) generated by A* in the parition lattice of V is called generalized relation lattice. The set of the granules in L(A*) whose cardinality is above certain threshhold is the set of all possible patterns derivable from the given attributes (features) of the given relation.
