Concept hierarchies are important for generalization across database/data mining applications. From store catalogs and news services, to community classifieds, hierarchies are ubiquitous. We introduce a new variation of Tree Encoding with Nested Intervals by leveraging “Carry-along Sort” to generate hierarchies dynamically. “Carry-along Sort” is an algorithm to build a generational hierarchy (materialized)path dynamically from the outline number column. It could be considered as a “Mix-in” between adjacency and Materialized path. There is no algorithm provides such flexibility to generate Nested Intervals as well materialized path together except “Carry-along Sort” algorithm. The implementation of this new algorithm was done in SQL Server and the complete algorithm was tested.
