Description: A synonym in the context of databases is an alias used to refer to a database object, such as a table, view, stored procedure, or sequence, with a different name than the original. This functionality allows users to interact with database objects more flexibly and understandably, facilitating query writing and data management. Synonyms are especially useful in environments where object names may be long or complicated, or when there is a desire to hide the complexity of the database structure from end users. Additionally, synonyms can help maintain compatibility with applications that rely on specific names, even if the underlying objects change. In terms of security, synonyms can allow access to objects without granting direct permissions on them, adding an extra layer of control over who can view or manipulate the data. In summary, synonyms are valuable tools in database management, providing a way to simplify and enhance interaction with data.
