Virtuoso Platform Overview

  1. 1. Virtuoso Platform Overview
  2. 2. The Enterprise Challenge Enterprises are increasingly looking to Data for driving agility via Systems-Of-Intelligence fed by existing Systems-Of-Engagement and Systems-Of-Record. Unfortunately, this pursuit is stifled by the prevalence of Data Silos created by Applications. 2 License CC-BY-SA 4.0 (International)
  3. 3. A Knowledge Graph Platform that leverages Hyperlinks as “Super Keys” for powerful integration of Data across Disparate Data Sources. Thereby unleashing Data as “a new force” conducted by Hyperlinks that brings the magic behind the World Wide Web to Data Access, Integration, and Management. The Solution 3 License CC-BY-SA 4.0 (International)

  21. 21. Creating Linked Data License CC-BY-SA 4.0 (International)
  22. 22. Creating Linked Data using Virtuoso - 1 Basic process without a line of code: • Identify a Data Source of interest that’s accessible via HTTP • Provide Data Source URL to Virtuoso’s Sponger Middleware Component • RDF Linked Data is generated and persisted to the underlying Quad Store aspect of the core DBMS 22 License CC-BY-SA 4.0 (International)
  23. 23. Creating Linked Data using Virtuoso - 2 Using the Built-In Crawler: • Identify an RDF document collection location • Setup a scheduled Crawler Job • Run Crawler Job 23 License CC-BY-SA 4.0 (International) Using the Bulk Loader: • Identify an RDF dataset • Download to a folder within Virtuoso’s installation setup • Run the RDF Bulk Loader Procedure
  24. 24. Creating Linked Data using Virtuoso - 3 Using SPARQL: • Write SPARQL 1.1 INSERT, UPDATE, DELETE queries directly • Set ACID constraints via Pragmas • Apply SHACL Evaluation to Named Graphs associated with INSERT, UPDATE, and DELETE operations 24 License CC-BY-SA 4.0 (International) Using SPASQL (SPARQL from SQL): • Write SPARQL 1.1 INSERT, UPDATE, DELETE queries directly, using SQL • Set ACID constraints via Pragmas • Apply SHACL Evaluation to Named Graphs associated with INSERT, UPDATE, and DELETE operations
  25. 25. Data Virtualization via RDF Views over ODBC or JDBC Accessible SQL- Data Sources License CC-BY-SA 4.0 (International)
