LIVE: A Lineage-Supported Versioned DBMS

Das Sarma, Anish and Theobald, Martin and Widom, Jennifer (2009) LIVE: A Lineage-Supported Versioned DBMS. Technical Report. Stanford InfoLab.




This paper presents LIVE, a complete DBMS designed for applications with many stored derived relations, and with a need for simple versioning capabilities when base data is modified. Target applications include, for example, scientific data management and data integration. A key feature of LIVE is the use of {\em lineage} (provenance) to support modifications and versioning in this environment. In our system, lineage significantly facilitates both: (1) efficient propagation of modifications from base to derived data; and (2) efficient execution of a wide class of queries over versioned, derived data. LIVE is fully implemented; detailed experimental results are presented that validate our techniques.
