The Big Data Challenge

Discover New & Intriguing Insights

by Integrating

Data Across Internal & External Data Sources


The Data Access Challenge

Exploit New & Emerging Data Access Frontiers

Using

Existing ODBC compliant Applications?


What is Data?

Subject Observation Representation.

Basically:

Every “Observation Subject” has a Name, discernible Attributes, and

“Attribute Values”.


What is Structured Data?

Schema Constrained Data Representation

Where the following are human and/or machine

discernible:

Unique Subject Name

Subject Attributes

Subject Attribute Values.


CSV based Structured Data

Entity,Attribute,Value

#France, #Type, #PopulatedPlace

#France, #hasLabel, ”France”

#France, #hasCapital, #Paris

#Paris, #Type, #PopulatedPlace

#Paris, #hasLabel, ”Paris”

#PopulatedPlace, #Type, #Place


TSV based Structured Data

Entity<TAB>Attribute<TAB>Value

#France<TAB>#Type<TAB>#PopulatedPlace

#France<TAB>#hasLabel<TAB>”France”

#France<TAB>#hasCapital<TAB>#Paris

#Paris<TAB>#Type<TAB>#PopulatedPlace

#Paris<TAB>#hasLabel<TAB>”Paris”

#PopulatedPlace<TAB>#Type<TAB>#Place


Structured Data (Table/Spreadsheet)

Entity (Subject) Attribute (Predicate) Value (Object)

#France #Type #PopulatedPlace

#France #hasLabel “France”

#France #hasCapital #Paris

#Paris #Type #PopulatedPlace

#Paris #hasLabel “Paris”

#PopulatedPlace #Type #Place


What is Linked Data?

Basically, Hyperdata!

Enhanced Structured Data Representation

Via

Hyperlinks.


What Are Hyperlinks?

Live References To Content.

These References my be local (Green Hyperlinks from Windows Help)

Or

Network aware (Blue Hyperlinks as per World Wide Web & Other HTTP Networks).


Local Linked Data using URIs

Entity (Subject) Attribute (Predicate) Value (Object)

urn:data:object:id:France urn:data:object:id:Type urn:data:object:id:PopulatedPlace

urn:data:object:id:France urn:data:object:id:hasLabel “France”

urn:data:object:id:France urn:data:object:id:hasCapital

urn:data:object:id:Paris

urn:data:object:id:Paris urn:data:object:id:Type urn:data:object:id:PopulatedPlace

urn:data:object:id:Paris urn:data:object:id:hasLabel “Paris”

urn:data:object:id:PopulatedPlace

urn:data:object:id:Type urn:data:object:id:Place

Massive Linked Open Data Cloud


http://richard.cyganiak.de/2007/10/lod/


SQL Query Language Benefits?

Declarative Query Language for Access, Manipulation, and Definition of

Structured Data Stored in Relational Database Management Systems

(RDBMS)


ODBC Benefits?

Standard Application Programming Interface (API) for SQL based

Access to RDBMS hosted Data.


SPARQL Query Language Benefits?

Declarative Query Language for Access, Manipulation, and

Definition of Linked Data based on the Entity-Attribute-Value/RDF

Data Model.


SPARQL Protocol Benefits

HTTP based Protocol (Web Service) for executing SPARQL commands against Public or Private Linked

Data Sources.


SQL Query Language Challenges

Access to Data outside Relational Database Management Systems.


ODBC Driver Problems?

Access to Data outside Relational Database Management Systems.


Virtuoso ODBC Driver Benefits?

Cross Platform ODBC Driver that treats Linked Big Data on the Web

(or elsewhere) like any another ODBC accessible RDBMS!

How Do I Get Going?

Download, install, and experience the power of coherent integration of disparate data sources, data access protocols, and data representation formats.

In an nutshell, commence exploitation of powerful business intelligence, socially enhanced collaboration, data virtualization, and entity analytics without writing a line of code!

Turn "Big Data" into exploitable "Smart Data" without compromise!

How Does Virtuoso Expose LOD Cloud Data To ODBC Clients?

Creation of ODBC accessible SQL Views using SPASQL (SPARQL inside SQL) that targets local data

Ditto via SPARQL-FED (Federated SPARQL) for external SPARQL endpoints.

Example instances include:

DBpedia (Linked Data version of Wikipedia content and LOD Cloud nexus)

URIBurner Service for “on the fly” transformation of data from: LinkedIn, Facebook,

Twitter, Google+, Freebase, Disqus etc.

Live Linked Open Data LOD Cloud Cache.

Demo Query Tools

Microsoft Access (Windows)

Filemaker (Mac OS X)

Tibco SpotFire (Windows)

Tableau Deskop (Windows)

SAP Crystal Reports (Windows)

HTML5 based ODBC Explorer (Browser) – requires local ODBC Driver Manager

HTML5 based XMLA Explorer (Browser) – no local ODBC Driver Manager required

Virtuoso Conductor

Virtuoso iSQL

Any other ODBC compliant tools that offers a SQL Query Editor.

Federated SPARQL (SPARQL-FED)Queries


How It Works

Construct or Locate SPARQL Query of interest

Verify Query against its original SPARQL Endpoint

Go to a Virtuoso SPARQL endpoint and execute a Federated SPARQL (SPARQL-

FED) variant of query

Using any ODBC compliant application, execute SPARQL pass-through queries by

placing the pragma “SPARQL” before your Basic or Federated SPARQL query text.

How It Works

Construct or Locate SPARQL Query of interest

Verify Query against its original SPARQL Endpoint

Go to a Virtuoso SPARQL endpoint and execute a Federated

SPARQL (SPARQL-FED) variant of query

Via Virtuoso’s native or ODBC SQL client interfaces issue standard

SQL CREATE VIEW syntax to construct a SQL View from the
