CSN, which stands for "consistent, stable, and normalized", is usually an acronym used in the field of database management. The term describes a state in which data is genuine, accurate, and reliable. Since the term is an acronym, there aren't any synonyms that directly relate to the three words that make up the term. Nevertheless, in the database management system, terms like "persistent," "dependable," and "consistent" can cover similar meanings to some extent. Therefore, when it comes to database management, the terms used to describe data are limited, and while there may not be direct synonyms, there are similar terms that can be used to convey similar ideas.
