Is it possible to have a table in a database that has no primary foreign key match up?
The table will be holding file paths to particular files and directories that I want to upload which doesn’t relate to any of the other tables in the database. Is this good practise or should all tables have a primary foreign key match up? If so should I create a separate database with just this table?
Every table should have a key but that doesn’t mean it has to have a foreign key referencing it. The purpose of the key is to ensure that data is uniquely identifiable and guarantee that the expected set of dependencies is enforced.
