Title: Index Structure for the Fact Table of a Star-Join Schema and Template Query Processing
Keywords: Star-Join Schema, Fact Table, Multilevel Index, Query Processing, Stream Processing

Abstract: Star-join is a database scheme designed for the purpose of data warehousing. A typical query on a star-join scheme as well as an algorithm for its processing has been examined. An index structure for the star-join fact table has been proposed with the aim of facilitating template query processing. A multilevel index for the fact table’s composite key has been build having time_key as a top level. Stream processing technique has been implemented for resolving query’s application and join constraints as well as the aggregation step of the query processing algorithm
