 note = {In recent years, data provenance or lineage tracing has become an acute issue in the database research. Our target is the dataprovenance issue in peer-to-peer (P2P) networks where duplicates andmodifications of data occur independently in autonomous peers. To ensure reliability among the exchanged data in P2P networks, we haveproposed a reliable record exchange framework with tracing facilitiesbased on database technologies in [5, 6]. The framework is based on the "pay-as-you-go" approach in which the system maintains the minimumamount of information for tracing with low maintenance cost and a userpays the cost when he or she issues a tracing query to the system. Thispaper focuses on its two alternative query processing strategies and compare their characteristics according to the performance., Proceedings of the 14th International Conference on Database Systems for Advanced Applications (DASFAA 2009), Vol. 5463 of Lecture Notes in Computer Science, pp. 323-327, Brisbane, Australia, April 2009, Springer-Verlag.},
