The data storing and retrieving are playing a major role in the data clustering and data warehousing techniques. The effectiveness of a data retrieving method depends upon the data specific queries for retrieving the data from the database. Iceberg query is a unique class of aggregation query, which computes aggregate values above a given threshold. Many data mining queries are basically ice berg queries. The major part taken into the consideration about the AND operation in the iceberg queries. The reduced number of AND operation increases the effectiveness of the iceberg query. In this paper, an efficient iceberg query evaluation process is proposed by reducing the bitwise AND operations needed to find the item pairs.
