Vers une conception logique et physique des bases de données avancées dirigée par la variabilité

Abstract : The evolution of computer technology has strongly impacted the database design process which is henceforth requiring more time and resources to encompass the diversity of DB applications.Note that designers rely on their talent and knowledge, which have proven insufficient to face the increasing diversity of design choices, raising the problem of the reliability and completeness of this knowledge. This problem is well known as variability management in software engineering. While there exist some works on managing variability of physical and conceptual phases, very few have focused on logical design. Moreover, these works focus on design phases separately, thus ignore the different interdependencies. In this thesis, we first present a methodology to manage the variability of the whole DB design process using the technique of software product lines, so that (i)interdependencies between design phases can be considered, (ii) a holistic vision is provided to the designer and (iii) process automation is increased. Given the scope of the study, we proceed step-bystepin implementing this vision, by studying a case that shows: (i) the importance of logical design variability (iii) its impact on physical design (multi-phase management), (iv) the evaluation of logical design, and the impact of logical variability on the physical design (materialized view selection) in terms of non-functional requirements: execution time, energy consumption and storage space.
