EaChOff: Chunk offset compression scheme for high dimensional data based on Extendible Multidimensional Array

The Traditional Multidimensional Array (MA) is not extendible during run time and also it creates high degree of sparsity for picturing the actual data. Therefore it is important to find good storage scheme to compress the high dimensional data so that the maintenance becomes easier. To solve these sparsity and dynamic extension problem, we introduce a new methodology EaChOff (Extendible Multidimensional Array based Chunk Offset Compression). The EaChOff linearizes each subarray of the EMA independently and break it into chunks for compressing. We evaluated our proposed schemes by comparing compression ratio and range of usability for Chunk-Offset Compression on MA. The analysis shows that the proposed scheme is efficient if dynamic behavior of the schema is concerned for practical applications.
