🆓Warning
Always follow naming conventions for synonyms.
Reason
SQL identifiers share the same namespace as PL/SQL identifiers. Follow naming conventions to prevent naming conflicts, improve readability, and clearly indicate the scope without forcing the use of qualified names. A common practice is to use a prefix and/or suffix to distinguish the identifier types.
Recommendations
Synonyms should be used to address an object in a foreign schema rather than to rename an object. Therefore, synonyms should share the name with the referenced object.
