We describe a new approach to data integration which subsumes the previous approaches of local as view (LAV) and global (GAV). Our method, we term both (BAV), is based on use reversible schema transformation sequences. show how LAV GAV definitions can be fully derived from BAV sequences, sequences may partially or definitions. also supports evolution schemas, discuss ongoing implementation within AutoMed project.
Abstract. Recent years have witnessed a growing realization that the development of large data‐intensive, transaction‐oriented information systems is becoming increasingly more difficult as user requirements become broader and sophisticated. Contemporary approaches been criticized for producing which are to maintain provide little assistance in organizational developments. This paper introduces TEMPORA paradigm, currently under advocates closer alignment between policy system functionality....
This paper presents SPOWL, which uses Spark to perform OWL reasoning over large ontologies. SPOWL acts as a compiler, maps axioms in the T-Box of an ontology programmes, will be executed iteratively compute and materialise closure results entailed by ontology. Such is then available queries retrieve information from Compared MapReduce, adopting enables cache data distributed memory, reduce amount I/O used, also parallelise jobs more flexible manner. We further analyse dependencies among...
In this paper we survey and measure the performance of methods for reasoning using OWL-DL rules over data stored in an RDBMS. Reasoning may be broken down into two processes classification type inference. context databases, is process deriving additional schema constructs from existing a database, while inference inferring values tables/columns other tables/columns. Thus it that focus paper, since as are inserted there need to use derive new facts.
