1 Oracle Spatial Summit 2015 Hybrid Cloud Using Oracle DBaaS: How the Italian Workers Comp Authority Uses Graph Technology Patrizio Galasso, Information Governance Manager, Inail Giovanni Corcione, Master Principal Sales Consultant, Oracle Italia

2 INAIL Workplace Accidents linked data system OVERVIEW Inail, the Italian Government Workers Compensation Authority, a public non-profit entity safeguarding workers against physical injuries and professional diseases. +10K employees - management of about 600K incidents and 60K professional diseases per year Services for +3 million Italian companies virtual servers, 520 phisical servers ULA: Oracle DBMS EE+Options - SOA,BPM,WEBCENTER, WLS OBI EE. CHALLENGES / OPPORTUNITIES 5 stars W3C OpenData model Endpoint service. Inail scalable RDF-Graph triplestore. Zero impact on Inail IT infrastructure SOLUTIONS Oracle Cloud DBaaS, DBMS 12.1 EE High Performance Spatial and Graph - RDF-Graph Partitioning - Multitenant Oracle Fusion Middleware RESULTS Linked Open Data system UE/Italian Gov Agency compliance 10 Italian Regions: about 90M RDF triples Security: infrastructure separation provided by PaaS Cloud services. Semantic interoperability with Italian federated Linked Open Data Rapid implementation, -3 days, with significant operational cost reduction. Query simplification for complex analysis Inail now better understands activities to deploy additional linked data for both internal and public services

3 Objectives Workplace Accidents Linked OpenData Endpoint Service Scalabale Triplestore Zero impact on Inail IT infrustructure Reduce operational costs without compromising data security A minimal ontology to represent basic concept about Accidents at Work A specialised ontology to infer restricted fare insurance on accidents and injuries 3
