The purpose of this project is to create a quality-aware database system that fundamentally extends standard database management systems to support imperfect database with evolving qualities. In the real world, the management and query processing of imperfect databases is a very challenging problem as it requires incorporating the data¡¯s qualities within the database engine. In this project, quality-aware database introduces a new quality model that captures the evolution of the data¡¯s qualities over time and a new query algebra focused on selection and join that enables seamless and transparent propagation and derivations of the data¡¯s qualities within a query pipeline. As a result, a query¡¯s answer will be automatically annotated with quality-related information at the tuple level.
