TRAC: Toward Recency and Consistency Reporting in a Database with Distributed Data Sources

Summary: TRAC reports recency and consistency for queries over distributed logs centralized in a DBMS. Instead of enforcing currency, it annotates results with recency and consistency metadata and provides techniques to compute them, demonstrated by a prototype with experiments.
