In 1990, W. Cellary and G. Jomier proposed the Database Version (DBV) approach, which allows to manage multiversion databases - those in which several versions of a set of data items coexist. Ever since, its model, theory and algorithms have been adopted in a multitude of research initiatives and publications, and have been applied to a variety of applications, in particular those in which there is a need for keeping track of parallel or (spatio)-temporal evolution of states of the world. This article presents an overview of the DBV approach, and some of the associated research initiatives throughout three decades, pointing out new potential directions. It has been written in tribute to Geneviève Jomier, Prof. Emeritus of The Université Paris-Dauphine, who left us in March 2018.
