Ram Meghe COEM, Badnera, Amravati, Maharashtra, India ABSTRACT This research describe in this paper is a new approach of partial query processing based on a SAX query parser and Query engine. It first loads the compressed XML document and then processes. The brief description of proposed scheme is presented, followed by the design. This begins with the introduction discussion experimental results, followed by its evaluation and compressions with some other existing technologies. KEYWORDS: XML Parsing, XVSGC Approach, Data Compression, Partial Decompression, Quriable Compression INTRODUCTION Query processing plays a vital role in the database system. However little work has been done to study the effective compression and query processing in XML documents. Query processor refers to a collective set of strategies that processes the queries in some sort of time. The basic component of any query processor is the parser and the Query engine. Query engine attempt to resolve the query. Search engine and the Parser is heart of the query processor. Search engine searches the exact match for the incoming queries and then it optimize it for the result. The compression time for XML database is calculated by running the same database For multiple times and average is taken for consideration of result. The main reason for doing this is to reduce the disk I/O influences on the results by loading the whole document into the physical memory.. Calculations of CR1 and CR2 are done using the following formulas- The compression ratio is defined as follows CR1=(Size of Compressed File *8)/Size Of Original File CR2=1-(size of Compressed file /Size of Original File)*100 Compression Ratio Factor (CRF):- Normalize the Compression Ratio of XVSGC with Respect to XMill and XGRIND CRF 1=CRXVSGC/XMILL CRF 2=CRXVSGC/XGRIND Compression Time Factor (CRT):- Normalize the Compression Time of XVSGC with Respect to XMill and XGRIND. CRT1=CRTXVSGC/XMILL CRT 2=CRTXVSGC/XGRIND
