Revisit the naming of relations

[gabor-boros]

Description

Ensure that all relation names in the Graph Database are meaningful, relevant, and consistent.

Some relation names in the Graph DB may sound unrelated, unclear, or misleading. This can cause confusion for developers and contributors who work with the data model.

Tasks

1. Review all relation names.
2. Identify any names that:
   • Don’t clearly represent their purpose.
   • Sound unrelated to the entities they connect.
   • Break naming consistency with similar relations.
3. Rename these outliers to more suitable and descriptive names.
4. Update:
   • Related queries
   • Documentation
   • Tests
5. Verify that all Graph DB operations still work as expected after changes by running tests

Notes

• Favor clarity over brevity when renaming.
• Keep naming consistent with the rest of the data model.
• Avoid introducing abbreviations unless they are widely understood in context.
