MM-cat

Summary: 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 separate website is maintained at https://www.ksi.mff.cuni.cz/~koupil/mm-cat/index.html.

MM-cat demo is available at demo.mmcatdb.com.

Multi-model databases

Relatively recently emerged NoSQL and other modern database management systems allowed to deploy databases based on other logical models than just the traditional relational. Unfortunately, the number of available models, formats, implementations, and query languages the existing systems exploit, often proprietary, is not sustainable from a longer perspective. Therefore we focus on various aspects of efficient and unified management of multi-model data, including conceptual modeling, schema inference, unified querying, or evolution management.
