Subject-predicate-object databases basically construct [[w:semantic]] networks from interlinked atomic units called a [[w:triplet]].
Subject-predicate-object databases basically construct [[w:semantic]] networks from interlinked atomic units called a [[w:triplet]] so they are not fundamentally different from graph databases in functionality and utility offered.


These networks may be queried with a suitable query language such as [[w:SPARQL]] which in practice allows you to compose semantic queries.

A [[w:triplestore]] maybe a native implementation from ground up or be standing on the shoulders of a standard RDBMS system where actual [[w:SQL]] is formulated by the interpreter and then queried from SQL. This probably has upsides and downsides.
