37ème Conférence sur la Gestion de Données – Principles, Technologies et Applications

25-28 octobre 2021, en ligne et Ecole Normale Superieure de Paris

Les 37èmes journées de la conférence BDA « Gestion de Données – Principes, Technologies et Applications », rendez-vous incontournable de la communauté gestion de données en France, auront lieu cette année à Paris, du 25 au 28 octobre 2021, dans le campus de l’Ecole normale supérieure, au cœur du Quartier latin (45, rue d’Ulm Paris).

La recherche en gestion de données n’a jamais été aussi active, variée, ouverte sur d’autres champs de l’informatique et, au-delà, sur les grands défis des applications modernes. Poursuivant la tradition de rencontres annuelles de la communauté de gestion de données francophone, BDA 2021 invite académiques et industriels à soumettre leurs travaux récents pour rendre compte des défis et des avancées scientifiques et industrielles dans ce domaine en pleine effervescence.

La site de soumission est ouvert

Anastasia Ailamaki Nothing is for granted: Making wise decisions using real-time intelligence

Abstract:
In today’s ever-growing demand for fast, data-driven decisions, heterogeneity severely undermines performance and fragments efforts for building unified data exploration tools. The variety in data formats and workloads forces data pipelines to be manually split across a variety of task-specialized systems and combined through expensive ETL and orchestration processes, or to adapt both the data and the workloads to match the requirements of a single-system, sacrificing expressiveness and structural information. Furthermore, the ever-increasing hardware heterogeneity causes task-based specialization of the tools to specific hardware such as CPUs or GPUs, forcing a trade-off: designing optimized hardware often means wasting accelerator-level parallelism (ALP) opportunities or tolerating slow and unnecessary communication between devices. In general, data processing is adapted to the pre-determined data processing system architecture, losing valuable information in the translation.

Real-time intelligence means to make all decisions during execution, when all relevant information is available for optimal utilisation of resources, while it also learns and extracts information about the query requests, instead of depending on pre-determined workload expectations. I will show how designing top-down the system architecture to allow a data- and workload-driven just-in-time specialization enables fast query execution over unprepared, potentially dirty data without time consuming preparation, as well as efficient orchestration and utilization of heterogeneous hardware devices.

Georgia Koutrika The Rise of Intelligent Data Assistants: Democratizing Data Access

Abstract:

For many, data is considered the 21st century’s most valuable commodity growing at an exponential rate – but is it for everyone? Analysts exploring data sets for insight, scientists looking for patterns, and consumers looking for information are just a few examples of user groups that need to access and dig into data. However, existing data exploration tools are falling behind in bridging the chasm between data and users, making data exploration intended only for the few. In this talk, we will discuss about what it takes to bridge this chasm and the new generation of intelligent data exploration tools that are emerging at the intersection of data management, natural language processing, machine learning and visualization. The talk will end with a summary of open questions on intelligent data assistants.

Benjamin Nguyen Privacy Preserving Contact Tracing : a case of privacy driven data analysis

Abstract:

Classical contact-tracing is a technique during an epidemy to slow down contamination. Classical contact tracing is organized by medical personnel during an (intrusive) interview with a patient suffering from the disease, in order to trace back all the other people whom the patient was in contact with, in order to informe them of the possibility of contamination.

During the Covid19 pandemic, contact tracing has been pushed to a new level, via automation. However, due to the sensitive nature of the information that is manipulated in order to achieve good tracing, building a privacy preserving solution, while still maintaining the quality of the results proved to be a compelling research challenge. During this presentation, we will present the data management and privacy issues around privacy preserving contact tracing, and discuss in more detail the two main solutions deployed in Europe, the French lead ROBERT (aka StopCovid/TousAntiCovid) proposal, and the Swiss lead DP3T, later adapted by Apple and Google.

Benjamin Nguyen graduated from ENS Cachan in 2000. He obtained his Ph.D from University of Paris Sud in 2003 on data warehousing, and his HDR from University of Versailles in 2013 on privacy preserving data mangement. Since 2014, he holds a professor position in the Systems and Data Security team of the Laboratoire d’Informatique Fondamentale d’Orléans (LIFO), at INSA Centre Val de Loire and is an external collaborator of the Inria Private and Trusted Cloud (PETRUS) team. His current research topics cover anonymization techniques, models and methods to represent, quantify and enforce privacy models (such as logics, secure hardware and cryptography), and the design and implementation of large scale privacy-by-design information management systems. Pr. Nguyen is head of LIFO since 2016, and co-chair of the Privacy Working group of the CNRS research group on Computer Security since 2016.
