Abstrakt
In our demonstration,we present our prototype implementation of a tool calledMM-evolver.MM-evolvercarries out user-triggered schema modifi-cation operations over a multi-model database, and propagatesthem across all models. As a novelty,MM-evolversupports bothinter- and intra-model schema modification operators.
To thebest of our knowledge, ours is the first tool addressing evolutionmanagement in the world of multi-model databases.
