H-PRIMA

Overview

H-PRIMA is an efficient incarnation of PRIMA, which supports the same features of management and querying of transaction-database systems under schema evolution. PRIMA was based on XML DB that executes XQuery queries on XML data, which is not very efficient at the current state of art. In H-PRIMA, we instead employ RDBMS-based query execution engine, to improve the performance. We also address the problem of temporal coalesce for the broken history at schema changes.
