A collaborative framework for parallel view maintenance

Materialized view maintenance is an important research area in the database and data warehouse area. Currently, most of the view maintenance methods are based on the C/S model, which will lead to overload and even crash at the end of data warehouse. A model of P2P-based collaborative view maintenance is proposed, which can not only exploit the potential merits of P2P and CSCW, but also overcome the above mentioned problems. Furthermore, a collaborative maintenance algorithm is proposed. Finally, the evaluation shows the proposed strategy achieves better performance both on the message number and the total execution time.
