Abstract: A formal query approach called Hypergraph Query-by-Example (HQBE) is presented that can be applied in for large-scale data analysis, deliberating the user from the knowledge on specific query language details or even the database structure. The query construction of HQBE makes use of the hypergraph-based multidimensional artifacts and relations between them as the unifying data representation. Since the construction of a query is supported by a semantic discovery process and a traversal of relationship structures and data elements, the query hypergraph patterns could support the flexible on-demand analysis for obtaining the desired results.

Keywords: data warehousing; on-demand analysis; multidimensional modelling; query-by-example; query hypergraphs; data analysis.
