Is There a Comprehensive Naming Convention for MySQL?
While various naming practices exist, achieving consistency is paramount in database design. Your proposed conventions provide a solid foundation.
Table Naming:
- Stick to lowercase with underscores for word separation.
- Use singular names (e.g., "foo" instead of "foos").
- Consider adding a suffix for tables containing multiple records of the same type (e.g., "foo_list" or "foo_instances").
Primary Key Naming:
- Employ a self-incrementing primary key.
- Use the convention "tablename_id" (e.g., "foo_id" or "foo_bar_id").
Foreign Key Naming:
- Copy the column name from the referenced table (e.g., "foo_id" in "foo_bar" for a foreign key referencing the primary key of "foo").
- Consider adding a numbered suffix to accommodate multiple references (e.g., "foo_id_1" or "foo_id_2").
Referential Integrity Enforcement:
- Use the syntax "tablename_fk_columnname" (e.g., "foo_bar_foo_id" in the "foo_bar" table).
Additional Considerations:
- Provide consistent index naming, such as "foo_bar_idx1" or "foo_idx1."
- Use singular rather than plural forms for column and table names.
- Maintain consistency throughout all aspects of database naming to ensure organization and ease of maintenance.
