NDLI: Performance enhancement through replication in an object-oriented DBMS

Abstract	In this paper we describe how replicated data can be used to speedup query processing in an object-oriented database system. The general idea is to use replicated data to eliminate some of the functional joins that would otherwise be required for query processing. We refer to our technique for replicating data as field replication because it allows individual data fields to be selectively replicated. In the paper we describe how field replication can be specified at the data model level and we present storage-level mechanisms to efficiently support it. We also present an analytical cost model to give some feel for how beneficial field replication can be and the circumstances under which it breaks down. While field replication is a relatively simple notion, the analysis shows that it can provide significant performance gains in many situations.
