In this paper, we present an approach to query processing for paraconsistent databases in the presence of integrity constraints. Paraconsistent databases are capable of representi...
When integrating data coming from multiple different sources we are faced with the possibility of inconsistency in databases. A paraconsistent approach for knowledge base integra...
For several reasons a database may not satisfy a given set of integrity constraints (ICs), but most likely most of the information in it is still consistent with those ICs; and cou...
— Constraints play an important role in the efficient query evaluation in deductive databases. In this paper, constraint-based query evaluation in deductive databases is investi...
The SQL queries produced in XML-to-SQL query translation are often unnecessarily complex, even for simple input XML queries. In this paper we argue that relational systems can do ...
