DWEB: A Data Warehouse Engineering Benchmark [PDF]
Data warehouse architectural choices and optimization techniques are critical to decision support query performance. To facilitate these choices, the performance of the designed data warehouse must be assessed. This is usually done with the help of benchmarks, which can either help system users comparing the performances of different systems, or help ...

Architecture and Quality in Data Warehouses [PDF]
Most database researchers have studied data warehouses (DW) in their role as buffers of materialized views, mediating between updateintensive OLTP systems and query-intensive decision support. This neglects the organizational role of data warehousing as a means of centralized information flow control. As a consequence, a large number of quality aspects

A novel decision support system for designing and assessing phytoremediation‐to‐biofuel value chains
Abstract The design of biofuel value chains is a complex process due to the large number of stakeholders involved, seasonality in feedstock availability, security of supply, logistics costs, efficiency considerations, and its multi‐node nature. Decisions on designing phytoremediation‐to‐biofuel value chains are even more complicated, due to the ...

Modélisation et manipulation de données historisées et archivées dans un entrepôt orienté objet [PDF]
This paper deals with temporal and archive object-oriented data warehouse modelling and querying. In a first step, we define a data model describing warehouses as central repositories of complex and temporal data extracted from one information source. The model is based on the concepts of warehouse object and environment. A warehouse object is composed

The End of an Architectural Era for Analytical Databases [PDF]
Traditional enterprise warehouse solutions center around an analytical database system that is monolithic and inflexible: data needs to be extracted, transformed, and loaded into the rigid relational form before analysis. It takes years of sophisticated planning to provision and deploy a warehouse; adding new hardware resources to an existing warehouse
