This wiki reports the research advances of the Panta Rhei, a research project for data management under schema evolution.

The Panta Rhei project aims at providing powerful tools that: (i) facilitate schema evolution and guide the Database Administrator in planning and evaluating changes, (ii) support automatic rewriting of legacy queries against the current schema version, (iii) enable efficient archiving of the histories of data and metadata, and (iv) support complex temporal queries over such histories, and (v) automate the documentation and querying of metadata histories.
