Data Compression on Columnar-Database Using Hybrid Approach (Huffman and Lempel-Ziv Welch Algorithm)
Columnar Oriented Database is an enhance approach to service to service the needs of Business Intelligence. A Columnar Oriented Database Management system that stores content by columns rather than the row. This type of data differs from traditional database with regards to performance, storage requirements and easy to modification of the schema. One of the major advantage of column based datab...
متن کاملParallel Lempel-Ziv-Welch (PLZW) Technique for Data Compression
Data Compression is one of the most fundamental problems in computer science and information technology. Many sequential algorithms are suggested for the problem. The most well known sequential algorithm is Lempel-ZivWelch (LZW) compression technique. The limitation of sequential algorithm is that ith block can be coded only after the (i-1)th block has completed. This limitation can be overcome...
متن کاملLempel-Ziv Dimension for Lempel-Ziv Compression
This paper describes the Lempel-Ziv dimension (Hausdorff like dimension inspired in the LZ78 parsing), its fundamental properties and relation with Hausdorff dimension. It is shown that in the case of individual infinite sequences, the Lempel-Ziv dimension matches with the asymptotical Lempel-Ziv compression ratio. This fact is used to describe results on Lempel-Ziv compression in terms of dime...
متن کاملA Modified Lempel–ziv Welch Source Coding Algorithm for Efficient Data Compression
Lempel–Ziv Welch (LZW) algorithm is a well-known powerful data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch. The algorithm is designed to be fast to implement but is not usually optimal because it performs only limited analysis of the data. A modified LZW algorithm on source coding will be proposed in this paper to improve the compression efficiency of the existin...
متن کاملNetwork Coding Based on Chinese Remainder Theorem
Random linear network code has to sacrifice part of bandwidth to transfer the coding vectors, thus a head of size k log |T | is appended to each packet. We present a distributed random network coding approach based on the Chinese remainder theorem for general multicast networks. It uses a couple of modulus as the head, thus reduces the size of head to O(log k). This makes it more suitable for s...
