Singular or Plural Table Names: Which Naming Convention Should You Choose?

Database table naming convention: singular is better than plural

Academia recommends that database table names should be in singular form to reflect the singularity of the entity they represent. In practice, however, this rule often conflicts with practicality, leading to the dilemma of whether to stick to the singular form or choose the plural form.

Reason for choosing singular form:

• Concept: A table is a container and its name should reflect the content it contains. Just as a "bag" can hold apples regardless of the number, a table represents a collection of data regardless of the number of items.
• Convenience: Singular names are easier to derive and use. The singular form of an object is fixed, while the plural form may vary or be ambiguous.
• Aesthetics and order: Singular names create a logical hierarchy in master-detail table scenarios and enhance alignment and readability.

Reasons for choosing the plural form:

• Language habits: Plurals are often used in spoken language to emphasize the occurrence of multiple items.
• Clarity: The plural form can provide contextual information when the contents of the table are not immediately obvious.

Ultimately, the choice between singular and plural table names is subjective and depends on specific context and preference. However, using the singular form has many advantages, including simplicity, convenience, and better readability.

Therefore, for table names like "Users", it is recommended to retain the singular form "User", even though this may require the use of parentheses in some cases. This decision adheres to the principle of singular naming, enhances the logical flow of the database structure, and promotes consistency of use in all aspects of data management.
