Scalable Generation of Synthetic GPS Traces with Real-Life Data Characteristics
Database benchmarking is most valuable if real-life data and workloads are available. However, real-life data (and workloads) are often not publicly available due to IPR constraints or privacy concerns. And ev...

Instant-On Scientific Data Warehouses
In the dawn of the data intensive research era, scientific discovery deploys data analysis techniques similar to those that drive business intelligence. Similar to classical Extract, Transform and Load (ETL) p...

Data Vaults: A Symbiosis between Database Technology and Scientific File Repositories
In this short paper we outline the data vault, a database-attached external file repository. It provides a true symbiosis between a DBMS and existing file-based repositories. Data is kept in its original format w...

Building Virtual Earth Observatories Using Ontologies and Linked Geospatial Data
Advances in remote sensing technologies have enabled public and commercial organizations to send an ever-increasing number of satellites in orbit around Earth. As a result, Earth Observation (EO) data has been...

Benchmarking Adaptive Indexing
Ideally, realizing the best physical design for the current and all subsequent workloads would impact neither performance nor storage usage. In reality, workloads and datasets can change dramatically over time...

Macro- and Micro-parallelism in a DBMS
Large memories have become an affordable storage medium for databases involving hundreds of Gigabytes on multi-processor systems. In this short note, we review our research on building relational engines to ex...

A Multi-Query Optimizer for Monet
Database systems allow for concurrent use of several applications (and query interfaces). Each application generates an “optimal” plan—a sequence of low-level database operators—for accessing the database. The...

Load balanced query evaluation in shared-everything environments
In this paper, we present data threaded execution, a new strategy to exploit both, pipelining and intra-operator parallelism in shared-everything environments. Data threaded execution is intuitive, straightforwar...

In quest of the bottleneck — monitoring parallel database systems
Monitoring query processing has proven to be an effective technique to detect bottlenecks in sequential query execution systems' components. Monitoring distributed execution in parallel systems, however, is a ...
