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

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 - 1800 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 11.1.1.7

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

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

Executive Order 13642 of May 9, 2013

Making Open and Machine Readable the New Default for Government Information

Section 1. General Principles. 

Openness in government strengthens our democracy, promotes the delivery of efficient and effective services to the public, and contributes to economic growth. As one vital benefit of open government, making information resources easy to find, accessible, and usable can fuel entrepreneurship, innovation, and scientific discovery that improves Americans' lives and contributes significantly to job creation.
