- W2912186208 abstract "It is our great pleasure to welcome you to the 12th ACM International Workshop on Data Warehousing and OLAP -- DOLAP'09. This year's workshop continues its tradition of being the premier forum where both researchers and practitioners in the areas of data warehousing and on-line analytical processing can share their findings in theoretical foundations, current methodologies, and practical experiences.The mission of the DOLAP workshop is to identify and explore new directions for future research and development, as well as emerging application domains in the areas of data warehousing and OLAP. In recent years, research in these areas have addressed many topics, ranging from conceptual-level and methodological issues, which help designers to build effective decision-support applications, to physical-level issues, aiming at increasing the performance of these applications in order to deal with vast amounts of data. However, the successful use of data warehousing and OLAP technologies within organizations brings up new requirements and research opportunities, in particular to cope with non-traditional application domains, such as biological, multimedia, and spatio-temporal applications. The DOLAP workshop gives researchers and practitioners a unique opportunity to share their perspectives with others interested in the various aspects of the data warehousing and OLAP domains.The call for papers attracted 26 submissions, from 15 different countries and 3 continents, and 2 additional papers forwarded from CIKM. The program committee accepted 13 papers that cover a variety of topics, including multidimensional design, ETL process, and multidimensional queries. The papers in the area of multidimensional design address the discovery of functional dependencies, the partitioning of relational data warehouses, and data warehouse testing. This year there are many papers on the ETL process, which shows that this topic is getting increasing interest from the research community. These papers address a taxonomy for ETL activities, the automatic generation of ETL processes from conceptual models, the use of BPMN and BPEL for designing ETL processes, programming frameworks, cardinality estimation, and the generation of data quality rules and integration. Finally, the papers on multidimensional querying address query evaluation in distributed data warehouses, query recommendations, query languages based on XML, and answering of top-k queries via materialized views. We hope that these proceedings will serve as a valuable reference for warehousing and OLAP researchers and developers." @default.
