DBToaster: A SQL Compiler for High-Performance Delta Processing in Main-Memory Databases

Christoph Koch, Yanif Ahmad

We present DBToaster, a novel query compilation framework for producing high performance compiled query executors that incrementally and continuously answer standing aggregate queries using in-memory views. DBToaster targets applications that require effic ...

Efficient Model-driven Query Processing Based on Data Regeneration

Saket Sathe, Petre Alexandru Arion

Nowadays, sensor data is generated in large amounts. Stor- ing or transmitting all the sensor’s measurements might not be the ideal choice because of the volume (and rate) at which it is generated. But we also cannot easily discard it, since ev- ery data m ...

Adaptive Physical Design for Curated Archives

Anastasia Ailamaki, Debabrata Dash

We introduce AdaptPD, an automated physical design tool that improves database performance by continuously monitoring changes in the workload and adapting the physical design to suit the incoming workload. Current physical design tools are offline and requ ...

An Economic Model for Self-tuned Cloud Caching

Anastasia Ailamaki, Debabrata Dash

Cloud computing, the new trend for service infrastructures requires user multi-tenancy as well as minimal capital expenditure. In a cloud that services large amounts of data that are massively collected and queried, such as scientific data, users typically ...

Sharing of probabilistically correlated data in peer-to-peer networks

Roman Schmidt

The impact of Peer-to-Peer (P2P) networks on the Internet landscape is undisputed. It has led to a series of new applications, e.g., as part of the so-called Web 2.0. The shift from the classical client-server based paradigm of the Internet, with a clear d ...

Rational approach for the management of a medium size bridge stock

Eugen Brühwiler

Infrastructure managers of medium size bridge stocks are being faced with the task of approximating short, mid to long term financial needs for their infrastructure. This task is particularly demanding due to the lack of relevant information, in particular ...

A Conceptual View on Trajectories

Stefano Spaccapietra, Christine Parent, Christelle Vangenot, Maria Luisa Damiani, José Antonio Fernandes de Macedo

Analysis of trajectory data is the key to a growing number of applications aiming at global understanding and management of complex phenomena that involve moving objects (e.g. worldwide courier distribution, city traffic management, bird migration monitori ...

To Share or Not To Share?

Anastasia Ailamaki, Babak Falsafi, Frederick Ryan Johnson, Ippokratis Pandis

Intuitively, aggressive work sharing among concurrent queries in a database system should always improve performance by eliminating redundant computation or data accesses. We show that, contrary to common intuition, this is not always the case in practice, ...

Efficient query processing on unstructured tetrahedral meshes

Anastasia Ailamaki

Modern scientific applications consume massive volumes of data produced by computer simulations. Such applications require new data management capabilities in order to scale to terabyte-scale data volumes [32, 10]. The most common way to discretize the app ...

Semantic Overlay Networks

Karl Aberer, Philippe Cudré-Mauroux

In a handful of years only, Peer-to-Peer (P2P) systems have become an integral part of the Internet. After a few key successes related to music-sharing (e.g., Napster or Gnutella), they rapidly developed and are nowadays firmly established in various conte ...
