Abstract: This paper documents the data governance facilities in DBOS, a database-oriented operating system under construction at Stanford and MIT. Because all operating system state is stored in a high performance main-memory relational DBMS, DBOS has architected a novel data provenance system for all application data. This system uses a high-volume column store for historical provenance information, and provenance data can be queried in SQL. Hence, at its core, DBOS is a polystore data system. Complementing this capability are facilities motivated by GDPR including support for personal data, purposes, and the right to be forgotten.
