At last we shows the average of that time as our result. Graph is drawn using the our exprimental results. Graph is drawn using the input from our experiments.

Size C. Size Q. Query processor plays an important role in the database management system. Finally it can be concluded that using the proposed technique of compression of XML databases and query evaluation over it, will better improve the performance of XML database systems. Abramson, N.

An analysis of XML compression efficiency. Debra A. Lelewer and Daniel S. Elias, P. The objective of this chapter is to provide a better understanding on relevant theoretical frameworks and an up-to-date research trend of the XML compression. To achieve this goal, this chapter contains the following contents. First, various existing XML compression techniques are classified according to their characteristics.

The classified categories are schema-dependent compression and schema-independent compression, non-queriable compression and queriable compression, and homomorphic compression and non-homomorphic compression. The characteristics of each category are introduced in detail. Also, the compression performance of those compression techniques is summarized in terms of compression ratio, compression time, and decompression time.

Furthermore, based on their characteristics and experimental evaluation, appropriate XML compression techniques for different environments are recommended. Offer does not apply to e-Collections and exclusions of select titles may apply.

Several schema systems exist to aid in the definition of XML-based languages, while programmers have developed many application programming interfaces APIs to aid the processing of XML data.

The PDF combines three technologies: A subset of the PostScript page description programming language, for generating the layout and graphics. A structured storage system to bundle these elements and any associated content into a single file, with data compression where appropriate.
