Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

JReq: Database Queries in Imperative Languages

Willy Zwaenepoel, Emmanuel Cecchet, Christopher Ming-Yee Iu

Instead of writing SQL queries directly, programmers often prefer writing all their code in a general purpose programming language like Java and having their programs be automatically rewritten to use database queries. Traditional tools such as object-rela ...

Predicting Replicated Database Scalability from Standalone Database Profiling

Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet

This paper develops analytical models to predict the throughput and the response time of a replicated database using measurements of the workload on a standalone database. These models allow workload scalability to be estimated before the replicated system ...

Drivolution: Rethinking the Database Driver Lifecycle

George Candea, Emmanuel Cecchet

The current design of database drivers – a necessary evil for interacting with a DBMS – imposes undue burdens on those who install, upgrade, and manage database systems and their applications. In this paper, we introduce Drivolution, a new architecture for ...

Online Piece-wise Linear Approximation of Numerical Streams with Precision Guarantees

Willy Zwaenepoel, Emmanuel Cecchet

Continuous "always-on" monitoring is beneficial for a number of applications, but potentially imposes a high load in terms of communication, storage and power consumption when a large number of variables need to be monitored. We introduce two new filtering ...

Middleware-based Database Replication: The Gaps Between Theory and Practice

Anastasia Ailamaki, George Candea, Emmanuel Cecchet

2008

Large web or e-commerce sites are frequently hosted on clusters. Successful open-source tools exist for clustering the front tiers of such sites (web servers and application servers). No comparable success has been achieved for scaling the backend database ...

Performance Comparison of Middleware Architectures for Generating Dynamic Web Content

Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet

On-line services are making increasing use of dynamically generated Web content. Serving dynamic content is more complex than serving static content. Besides a Web server, it typically involves a server-side application and a database to generate and store ...

Specification and Implementation of Dynamic Web Site Benchmarks

Willy Zwaenepoel, Sameh Mohamed Elnikety, Emmanuel Cecchet

The absence of benchmarks for Web sites with dynamic content has been a major impediment to research in this area. We describe three benchmarks for evaluating the performance of Web sites with dynamic content. The benchmarks model three common types of dyn ...

Performance and Scalability of EJB Applications

Willy Zwaenepoel, Emmanuel Cecchet

We investigate the combined effect of application implementation method, container design, and efficiency of communication layers on the performance scalability of J2EE application servers by detailed measurement and profiling of an auction site server. We ...
