Information Retrieval Using Indexing Scheme for Tree Pattern Framework
Indexing an XML database in data warehouse is a complex problem. The major rationale for indexing XML database in data warehouse is owing to the heterogeneous and structural environment of XML data that can construct query pattern tedious. Existing techniques focused on clustering methods based on integrating the data warehouse with web data for On-Line Analytical Processing (OLAP) techniques. Through clustering process, fast retrieval of information is impossible because clustering technique exactly used for tree pattern building framework. Most XML indexing strategies split it into several sub-queries, and subsequently connect their results to present the response to the unique query. Join operations have been determined as the mainly time-consuming component in XML query processing for information retrieval.
