As the increasing usage of data generating devices like cameras, mobile phones, Auto-ID technologies, and so on, huge amount of data are created. Data compression is very important. In order to use the suitable compression methods on reducing the data volume, this paper uses iceberg-cubes to compress the data based on the entropy query mechanism. Using the definition of iceberg-cubes, this paper uses the entropy query principle for getting the key value from the original datasets. The iceberg-cubes are then used for generating the compressed data which should be stored in the hardware devices. It is observed that these proposed algorithms could achieve 32.46% compression ratio averagely.
