Different notions of provenance for database queries have been proposed and studied in
the past few years. In this article, we detail three main notions of database provenance …

Uncertain data have already widely existed in many practical applications recently, such as
sensor networks, RFID networks, location-based services, and mobile object management …

This chapter covers the Trio database management system. Trio is a robust prototype that
supports uncertain data and data lineage, along with the standard features of a relational …

Provenance, ie, the origin or source of something, is becoming an important concern, since it
offers the means to verify data products, to infer their quality, to analyse the processes that …

We propose a new approach to synthesize Datalog programs from input-output
specifications. Our approach leverages query provenance to scale the counterexample …

We study the complexity of computing a query on a probabilistic database. We consider
unions of conjunctive queries, UCQ, which are equivalent to positive, existential First Order …

This paper introduces uldb s, an extension of relational databases with simple yet
expressive constructs for representing and manipulating both lineage and uncertainty …

Event driven architecture is a paradigm shift from traditional computing architectures which
employ synchronous, request-response interactions. In this paper we introduce a conceptual …

摘要随着数据采集和处理技术的进步, 人们对数据的不确定性的认识也逐步深入. 在诸如经济,
军事, 物流, 金融, 电信等领域的具体应用中, 数据的不确定性普遍存在. 不确定性数据的表现形式 …

Due to numerous applications producing noisy data, eg, sensor data, experimental data,
data from uncurated sources, information extraction, etc., there has been a surge of interest …
