An Approach to Database Preference Queries Based on an Outranking Relation [PDF]
International Journal of Computational Intelligence Systems, 2012 In this paper, we describe an approach to database preference queries based on the notion of outranking, suited to the situation where preferences on different attributes are not commensurable.

Representation and Reasoning for Model of 3DR46 in Complex 3D Space
Jisuanji kexue yu tansuo, 2020 To remedy the deficiency of the existing methods on 3D direction relations, the 3DR46 direction relations model is proposed. The model can represent and distinguish 246 complex 3D direction relations. To process the dynamic of 3D direction relations, the

Uniform Reliability of Self-Join-Free Conjunctive Queries [PDF]
Logical Methods in Computer Science, 2022 The reliability of a Boolean Conjunctive Query (CQ) over a tuple-independent probabilistic database is the probability that the CQ is satisfied when the tuples of the database are sampled one by one, independently, with their associated probability.

A multi-set extended relational algebra: a formal approach to a practical issue [PDF]
, 1993 The relational data model is based on sets of tuples, i.e. it does not allow duplicate tuples an a relation. Many database languages and systems do require multi-set semantics though, either because of functional requirements or because of the high costs
