TOPIC

Continuing the tradition of previous successful DOLAP workshops, the DOLAP 2006 workshop provides an international forum where both researchers and practitioners in the field of Data Warehousing and OLAP can share their findings in theoretical foundations, current methodologies, and practical experiences.

PROGRAM

This year's program contains 12 papers that can be thematically grouped by the three major phases of a data warehouse lifecycle: design, construction and exploitation of a data warehouse. Starting from the exploitation of the data warehouse, the accepted papers reflect the most recent trends in the research community and present novel data mining and aggregation techniques - quite a bit far from the traditional OLAP style of warehouse querying. All three papers on data warehouse construction involve real world cases and build upon them to provide novel design methods and vision for data warehouse design and construction. The papers in the area of data warehouse design, at the same time, explore hard topics such as ETL, indexing, view selection and spatial warehousing, which persist in attracting the interest of the research community. Finally, since DOLAP is the premier venue for data warehouse research, the program had to include a brush-stroke of vision: to this end the pr!
 ogram hosts a paper on research directions for the field of data warehouse design as well as a keynote talk on the formal specification and optimization of ETL scenarios, by Prof. Timos Sellis.

INVITED TALK

Formal Specification and Optimization of ETL scenarios
(Timos Sellis, National Techn. Univ. of Athens)

This year's invited talk will be given by Prof. Timos Sellis who will present his work on a framework towards the modeling of Extract-Transform-Load (ETL) processes and the optimization of ETL workflows. The goal of this research was to facilitate, manage and optimize the design and implementation of the ETL processes both during the initial design and deployment stage and during the continuous evolution of a data warehouse.
