Three representations: relational database tables, "ordinary" logic and rdf triplets:
Relational database tables:
people id name salary 1 jaan 100 2 ants 200 cars id model owner 1 opel 1 2 ford 2 3 volvo 2
"Ordinary" logic:
people(1,jaan,100) people(2,ants,200) cars(1,opel,1) cars(2,ford,2) cars(3,volvo,2)
Rdf-style triplets (not in any concrete syntax):
tanel_people1 rdf:type people tanel_people2 rdf:type people tanel_people1 name "jaan" tanel_people1 salary 100 tanel_people2 name "ants" tanel_people2 salary 200 tanel_cars1 rdf:type cars tanel_cars2 rdf:type cars tanel_cars3 rdf:type cars tanel_cars1 model "opel" tanel_cars1 owner tanel_people1 tanel_cars2 model "ford" tanel_cars2 owner tanel_people2 tanel_cars3 model "volvo" tanel_cars3 owner tanel_people2
