Dataversifying Natural Sciences: Pioneering a Data Lake Architecture for Curated Data-Centric Experiments in Life \& Earth Sciences
Genoveva Vargas-Solar, Jérôme Darmont, Alejandro Adorjan +6
This vision paper introduces a pioneering data lake architecture designed to meet Life \& Earth sciences' burgeoning data management needs. As the data landscape evolves, the imper…
MATILDA: Inclusive Data Science Pipelines Design through Computational Creativity
Genoveva Vargas-Solar, Santiago Negrete-Yankelevich, Javier A. Espinosa-Oviedo +2
We argue for the need for a new generation of data science solutions that can democratize recent advances in data engineering and artificial intelligence for non-technical users fr…
Benchmarking Data Lakes Featuring Structured and Unstructured Data with DLBench
Pegdwendé Sawadogo, Jérôme Darmont
In the last few years, the concept of data lake has become trendy for data storage and analysis. Thus, several design alternatives have been proposed to build data lake systems. Ho…
Coining goldMEDAL: A New Contribution to Data Lake Generic Metadata Modeling
Etienne Scholly, Pegdwendé Sawadogo, Pengfei Liu +5
The rise of big data has revolutionized data exploitation practices and led to the emergence of new concepts. Among them, data lakes have emerged as large heterogeneous data reposi…
Automatic Integration Issues of Tabular Data for On-Line Analysis Processing
Yuzhao Yang, Jérôme Darmont, Franck Ravat +1
Companies and individuals produce numerous tabular data. The objective of this position paper is to draw up the challenges posed by the automatic integration of data in the form of…
Benchmarking Top-K Keyword and Top-K Document Processing with TK and TKD
Ciprian-Octavian Truica, Jérôme Darmont, Alexandru Boicea +1
Top-k keyword and top-k document extraction are very popular text analysis techniques. Top-k keywords and documents are often computed on-the-fly, but they exploit weighted vocabul…
TK: The Twitter Top-K Keywords Benchmark
Ciprian-Octavian Truică, Jérôme Darmont
Information retrieval from textual data focuses on the construction of vocabularies that contain weighted term tuples. Such vocabularies can then be exploited by various text analy…
Query Performance Optimization in XML Data Warehouses
Hadj Mahboubi, Jérôme Darmont
XML data warehouses form an interesting basis for decision-support applications that exploit complex data. However, native-XML database management systems (DBMSs) currently bear li…
A Survey of XML Tree Patterns
Marouane Hachicha, Jérôme Darmont
With XML becoming an ubiquitous language for data interoperability purposes in various domains, efficiently querying XML data is a critical issue. This has lead to the design of al…
Evaluating the Dynamic Behavior of Database Applications
Zhen He, Jérôme Darmont
This paper explores the effect that changing access patterns has on the performance of database management systems. Changes in access patterns play an important role in determining…
Benchmarking data warehouses
Jérôme Darmont, Fadila Bentayeb, Omar Boussaïd
Data warehouse architectural choices and optimization techniques are critical to decision support query performance. To facilitate these choices, the performance of the designed da…
An MAS-Based ETL Approach for Complex Data
Omar Boussaïd, Fadila Bentayeb, Jérôme Darmont
In a data warehousing process, the phase of data integration is crucial. Many methods for data integration have been published in the literature. However, with the development of t…
Knowledge and Metadata Integration for Warehousing Complex Data
Jean-Christian Ralaivao, Jérôme Darmont
With the ever-growing availability of so-called complex data, especially on the Web, decision-support systems such as data warehouses must store and process data that are not only…
An Architecture Framework for Complex Data Warehouses
Jérôme Darmont, Omar Boussaid, Jean-Christian Ralaivao +1
Nowadays, many decision support applications need to exploit data that are not only numerical or symbolic, but also multimedia, multistructure, multisource, multimodal, and/or mult…
Sélection simultanée d'index et de vues matérialisées
Nora Maiz, Kamel Aouiche, Jérôme Darmont
Indices and materialized views are physical structures that accelerate data access in data warehouses. However, these data structures generate some maintenance overhead. They also…
Un index de jointure pour les entrepôts de données XML
Hadj Mahboubi, Kamel Aouiche, Jérôme Darmont
XML data warehouses form an interesting basis for decision-support applications that exploit heterogeneous data from multiple sources. However, XML-native database systems currentl…
