Executive Summary

In this paper, the authors have presented a loss-less compression technique namely H-HIBASE (compression enhancement of HIBASE technique using Huffman Coding). Due to disk based compression, H-HIBASE supports very large database with acceptable storage volume. Insertion, deletion and update mechanisms on the architecture have been presented and analyzed. The architecture executes query directly on compressed data and it is capable of executing all types of SQL queries. The experimental evaluation has been performed with synthetic and real data. The experimental result has been compared with DHIBASE and widely used Oracle database. They have evaluated the storage performance in comparison with DHIBASE and Oracle database.
