In this paper the authors present the Item set extraction without using constraints, a general and compact structure which provides tight integration of item set extraction in a relational DBMS. Since no constraint is enforced during the index creation phase, It provides a complete representation of the original database. To reduce the I/O cost, data accessed together during the same extraction phase are clustered on the same disk block. The index structure can be efficiently exploited by different item set extraction algorithms.
