Abstract:

Spatial data warehouses provide a means of carrying out spatial analysis together with agile and flexible multidimensional analytical queries performed by SOLAP tools. However, queries are processed with slow query response times and functionalities of these tools are still insufficient, such as the support for a variety of spatial data warehouse schemas. In this paper, we conduct an experimental evaluation of existing open source software as SOLAP tool and database management system, to analyze its functionalities and query processing performance. Furthermore, we describe and evaluate our novel SOLAP tool called MapQuery that reuses efficient indices to boost query processing performance. Results derived from our performance evaluation indicated that MapQuery shortened the response time of queries from at least 63% up to 92% if compared to existing solutions.
