Mixed concurrency control: Dealing with heterogeneity in distributed database systems

Jean-François Pons, Jean-François Vilarem

A mixed concurrency control, which allows the two techniques -two phase locking and certification -to coexist together in the same distributed dambase system, proves to be advantageous in a number of situations : interconnected databases, static or dynamic heterogeneity of transactions or objects. In this paper we propose a method which seems well adapted to the majority of the forms of heterogeneity, by using dynamic calculation of a serialization order and concurrent control of all types of
