What are the reasons to use a chameleon method in data warehousing?

The hierarchical clustering of the algorithm that overcomes all limitations of the base models and methods that are present in the data warehousing in combination is called the Chameleon. This method operates as a sparse graph that has nodes, that is a Chameleon can represent data items and edges representing the need of the data items.

Chameleon representation is the one in the data warehouse that allows a large dataset to create and operate successfully. The method finds the clusters that can be used in the dataset using the two-phase algorithm.
