Relational Databases Ingestion into a NoSQL Data Warehouse

Autor: Abdelhedi, Fatma, Jemmali, Rym, Zurfluh, Gilles

The digital transformation of companies has led to the evolution of databases towards Big Data. Our work is part of this context and concerns more particularly the mechanisms to extract datasets stored in a Data Lake and to store the data in a Data W

Incremental extraction of a NoSQL database model using an MDA-based process

Autor: Brahim, Amal Ait, Ferhat, Rabah Tighilt, Zurfluh, Gilles

Publikováno v: Publication of the 2019 World Congress in Computer Science, Computer Engineering, and Applied Computing (CSCE 19 ) July 29 - August 01 , 2019 | Las Vegas, Nevada, USA

In recent years, the need to use NoSQL systems to store and exploit big data has been steadily increasing. Most of these systems are characterized by the property "schema less" which means absence of the data model when creating a database. This prop

Contraintes pour mod\`ele et langage multidimensionnels

Autor: Ghozzi, Faiza, Ravat, Franck, Teste, Olivier, Zurfluh, Gilles

Publikováno v: Bases de donn\'ees avanc\'ees 2003, Lyon : France (2003)

This paper defines a constraint-based model dedicated to multidimensional databases. The model we define represents data through a constellation of facts (subjects of analyse) associated to dimensions (axis of analyse), which are possibly shared. Eac

Alg\`ebre OLAP et langage graphique

Autor: Ravat, Franck, Teste, Olivier, Zurfluh, Gilles

Publikováno v: Congr\`es Informatique des Organisations et Syst\`emes d'Information et de D\'ecision - INFORSID'06, Hammamet : Tunisie (2006)

This article deals with OLAP systems based on multidimensional model. The conceptual model we provide, represents data through a constellation (multi-facts) composed of several multi-hierarchy dimensions. In this model, data are displayed through mul

Personnalisation de bases de donn\'ees multidimensionnelles

Autor: Ravat, Franck, Teste, Olivier, Zurfluh, Gilles

Publikováno v: Congr\`es Informatique des Organisations et Syst\`emes d'Information et de D\'ecision - INFORSID'07, Perros-Guirec : France (2007)

This paper deals with decision support systems resting on multidimensional modelling of data. Moreover, we intend to offer a set of concepts and mechanisms for personalized multidimensional database specifications. This personalization consists in as
