Exploration de la migration de la base de donnees relationnelle du systeme de gestion de processus d'affaires Oryx vers la base de donnees NO-SQL utilisee par la plateforme de l'informatique de nuage de Hadoop

The main objective of this research project is to explore the opportunity, to analyse the strategies and to assess the difficulties in integrating new technologies in the software engineering field. We based the realisation of our project on a case study we did by integrating an open source business management system (Oryx) that uses a SQLl data base into the NO-SQL database (Hbase).;This work has shown the software industry's great interest to this kind of projects and the lack of academic research in that field. It has allowed exploring the possibility of using an original hybrid model (SQL and NO-SQL) within the Oryx system.;The results may be used to consider the potential of a new SQL data model (hybrid model) on cloud computing platforms.
