27. Relational Database
Most Common
Data as rows/tuples
EMP_ID NAME HIRE_DATE SALARY

29. RDF
 Flexible and extensible way to represent information
 RDF can indicate membership
 RDF is a graph data model
 Triple : Subject Predicate Object
 The sky (subject ) has the color (predicate) blue (object)

30. Data Model
 emps:e13954 HR:name 'Joe'
 emps:e13954 HR:hire-date 2000-04-14
 emps:e13954 HR:salary 48000
Subject Predicate Object
emps:e13954 HR:name 'Joe'
emps:e13954 HR:hire-date 2000-04-14
emps:e13954 HR:salary 48000
21-Nov-08 30

31. Relationships
HR:emp
rdf:type
rdf:type
HR:supervises
emps:e10335
emps:e13954
HR:worksIn HR:dept
HR:manages
dept:sales rdf:type

32. SPARQL
 Simple Protocol and RDF Query Language
 SPARQL
SELECT ?id, ?sal
WHERE { ?id HR:salary ?sal }
 SQL
SELECT emp_id, salary
FROM employees
• extract information in the form of URIs, blank nodes, plain and typed literals.
• extract RDF subgraphs.
• construct new RDF graphs based on information in the queried graphs
