19 Semantics SLIDE: 19

20 Semantics: A New Way to Organize Data Data is stored in Triples, expressed as: Subject : Predicate : Object John Smith : livesin : London London : isin : England Query with SPARQL, gives us simple lookup.. and more Find people who live in (a place that's in) England "John Smith" "London" "England" livesin isin SLIDE: 20 livesin

21 Context from the World at Large Linked Open Data Facts that are freely available In a form that s easily consumed DBpedia (wikipedia as structured information) Einstein was born in Germany Ireland s currency is the Euro GeoNames Doha is the capital of Qatar Doha has these lat/long coordinates Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch.

24 Cluster Topologies XA RDBMS SLIDE: 24

25 Tiered Storage With Tiered Storage, you can Define data tiers based on a range index Have content balanced into forests by tier Move an entire tier to different storage Attach a tier to a different database Query one database on one tier or the other database on the other tier or both at once All with no downtime, and 100% consistency SLIDE: 25
