摘要：Trio is a new kind of database system that supports data, uncertainty, and lineage in a fully integrated manner. The first Trio prototype, dubbed Trio-One, is built on top of a conventional DBMS using data and query translation techniques together with a small number of stored procedures. Uncertain and probabilistic data are inherent in many important applications. Recently, considerable research efforts have been put into the field of managing uncertain data. This paper describes Trio-One’s translation scheme and system architecture, showing how it efficiently and easily supports the Trio data model and query language and also shows how aggregation is performed on uncertain and probabilistic data in TRIO system
