Which is a feature of a graph query language?

Graph query languages, like Oracle’s Property Graph Query Language (PGQL), are designed for graph

databases:

Correct Answer (D): “Ability to specify patterns” is a defining feature. Graph queries excel at defining

and matching patterns (e.g., nodes and edges) to explore relationships, such as finding paths or

subgraphs, critical for applications like social network analysis or fraud detection.

Incorrect Options:

A: Key-value queries are typical of NoSQL key-value stores, not graph databases.

B: While scripting may be possible in some contexts, it’s not a core feature of graph query languages.

C: Graph query languages are not inherently object-oriented; they focus on relational graph

structures.

This pattern-matching capability distinguishes graph queries from other query paradigms.
