It does because it is a consequence of the triple model. (03)

Oh yes, deltas. How easy compared to "delete from table where key='...'". (05)

So I can start a transaction with SPARQL (how do I do that ?), update some
data with SPARQL, query the updated data with SPARQL and the others do not
see the modified data until I commit the transaction ? (07)

I can do a SPARQL UPDATE and SQL DELETE on the *same* data ? How is this data
stored ? What is the underlying data model ? What happens to the SQL
"table row" if I delete one "triple" from it with SPARQL ? (09)
