Oracle Synonyms: Key Purposes and Uses

There are several uses for creating synonyms in Oracle.

1. Workers
2. The Employment Ministry
3. Hiding object location: Using synonyms to conceal the physical location of database objects allows applications to be unaware of which schema or database the object is in, increasing database security and maintainability.
4. Cross-mode access: Synonyms can be used to achieve cross-mode object access. Objects in different modes can be accessed using synonyms, simplifying object access permission management and cross-mode query complexity.
5. Multilingual support: Synonyms can be used to achieve multilingual support. Depending on the language environment, different synonyms can be used to access the translated objects, providing interfaces that cater to different languages.
6. Renaming: When you need to rename objects in the database, you can use synonyms to maintain compatibility with the application. By directing synonyms to the new object names, you can avoid modifying object references in application code.
   In general, creating synonyms can improve code readability, maintainability, and security, simplify object access and management, facilitate multilingual support and the renaming of database objects.
