使用 Oracle 公共同义词优化搜索体验（oracle公共同义词）
Data is the building block of the digital age. Regardless of industry, data serves as the backbone of businesses large and small. Oracle is a leading provider of relational database software with a multitude of tools to help extract and analyze data. One such offering is the ability to join disparate databases with Oracle Public Synonyms.
Oracle Public Synonyms are schema objects used to access objects within a database that do not share the same name. These synonyms are accessible to users with SELECT permission on the object. Public synonyms create an easy to use shortcut around the long, complicated paths necessary to access data.
The ‘CREATE PUBLIC SYNONYM’ command allows users to quickly create a synonym. Syntax is as follows:

Using a public synonym can provide a great experience for users during a search. An example would be a search across two databases that are linked by a public synonym. By using the public synonym, the user does not have to remember the long paths to the appropriate objects.
Oracle public synonyms do come with some disadvantages. Contrary to popular belief, only objects accessible to the user can be used through public synonyms. Additionally, permission management must be performed at the object level, since the public synonym has no authority.
Using public synonyms is a great way to optimize the search experience with Oracle databases. It is important to note that Oracle public synonyms are only available with certain versions of the Oracle database.
In conclusion, Oracle does provide users with the ability to use public synonyms to optimize the search experience. Public synonyms are great for joining two disparate databases without having to remember the specific object paths. However, users must be aware that Oracle public synonyms are limited in their scope and management capabilities for access control.
