An extensible toolset integrating techniques and approaches from two worlds - Web data exchange based on linked data specifications and multi-model data management.

DortDB is an extensible framework enabling cross-model queries combining well-known query languages and offering intuitive flexibility, format transformation, and optimization via a unified algebra.

FDepHunter is a novel and interactive method for dependency discovery that augments an Armstrong relation with additional tuples.

A modular and extensible framework that enables to design a multi-model schema. An initial ER schema is transformed to a unified categorical representation which can then be easily mapped to any combination of models in a particular DBMS, or their set.

A modular and extensible framework that ensures evolution management and backwards propagation to multi-model data. Following the current trends, the implementation can process also large amounts of data.

MM-evoque is a novel tool designed to propagate schema changes across multi-model databases and synchronise not only data but also respective queries to remain valid and performant.

A modular and extensible framework that ensures inference of a common schema of multi-model data. It enables to re-use verified single-model approaches, it is able to reveal both intra- and inter-model references as well as overlapping of models, i.e., data redundancy.

An automatic advisor for selecting workload-aware multi-model mappings. MM-mapsearch analyses a weighted workload, explores feasible schema variants using MCTS, and estimates their performance with a plan-structured neural predictor.

MM-quecat is a member of the multi-model data modeling and management tool family. Namely, the tool enables one to query multi-model data regardless of the underlying multi-model database or polystore.

ORMorpher addresses the challenge of translating between ORM frameworks by unifying entities, mappings, and queries into a common abstraction.
