Trio: A System for Integrated Management of Data, Accuracy, and Lineage
نویسنده
چکیده
Trio is a new database system that manages not only data, but also the accuracy and lineage of the data. Inexact (uncertain, probabilistic, fuzzy, approximate, incomplete, and imprecise!) databases have been proposed in the past, and the lineage problem also has been studied. The goals of the Trio project are to combine and distill previous work into a simple and usable model, design a query language as an understandable extension to SQL, and most importantly build a working system—a system that augments conventional data management with both accuracy and lineage as an integral part of the data. This paper provides numerous motivating applications for Trio and lays out preliminary plans for the data model, query language, and prototype system.

Trio-One: Layering Uncertainty and Lineage on a Conventional DBMS∗
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. This paper describes Trio-One’s translation scheme and system architecture, showing how it efficiently and ...

متن کاملData Modifications and Versioning in Trio
This paper presents the first DBMS for uncertain data that incorporates data modifications and a simple versioning system. Our work is in the context of Trio, a project at Stanford for managing data uncertainty and lineage. We establish SQL-based language constructs for data modifications, and an extended data model ULDB that supports these modifications yielding versioned relations. We show th...
