Visualizing data redundancy

http://www.soatrader.com/10-visualizing-data-redundancy.html

In one of my earlier blog entries I elaborated redundancy in federated information systems. The following picture illustrates such redundancy. Cluster map technology is used there to represent overlappings of entity attribute clusters. Each cluster represents entity attributes in an information system description. Overlapping areas represent entity attributes, which are potentially redundant, since they appear in several clusters at the same time.
