Accès non uniformément répartis dans une base de données: Généralisation d’une approche probabiliste. (French) Zbl 0697.68095

Summary: The study of transactions processing systems providing access to a database is based on the modelisation of the control policies for concurrent accesses. A hierarchical demarch was described by D. Potier and P. Leblanc. In a precedent paper, the authors proposed a probabilistic approach in case of one part of the database is more frequently accessed than the other. This paper proposes a generalization of the approach to more than two partitions and presents numerical results.
