OBDA approach has a great potential to facilitate such tasks; however, it has a number of limitations in dealing with analytics that restrict its use in important industrial applications. Based on our experience with Siemens, we argue that in order to overcome those limitations OBDA should be extended and become analytics, source, and cost aware. In this work we propose such an extension. In particular, we propose an ontology, mapping, and query language for OBDA, where aggregate and other analytical functions are first class citizens. Moreover, we develop query optimisation techniques that allow to efficiently process analytical tasks over static and streaming data. We implement our approach in a system and evaluate our system with Siemens turbine data." . @prefix ns9: . ns2:application-18 ns6:hasAuthorList ns9:authorList . @prefix ns10: . ns2:application-18 ns6:isPartOf ns10:proceedings . @prefix xsd: . ns2:application-18 ns6:keyword "Analytics"^^xsd:string , "Static Data"^^xsd:string , "Diagnostics"^^xsd:string , "OBDA"^^xsd:string , "Description Logic"^^xsd:string , "Streaming Data"^^xsd:string ; ns6:title "Towards Analytics Aware Ontology Based Access to Static and Streaming Data" . ns1:christian-neuenstadt foaf:made ns2:application-18 . ns1:christoforos-svingos foaf:made ns2:application-18 . ns1:ralf-moller foaf:made ns2:application-18 . ns1:yannis-ioannidis foaf:made ns2:application-18 . ns10:proceedings ns6:hasPart ns2:application-18 .
