Data storage systems usually assign unique identifiers to the entries they store.

Identifiers are commonly generated when the entry is first created. Once available, the identifier is stored *within* the entry and becomes *part of* the data. Anyone with access to the data is usually granted access to the `Id` column as well, simply because it is needed to uniquely identify a record for many data manipulation tasks. The identifier also serves as a pseudonym for the entry it refers to: regardless of access to other data such as `Name`, a subject can be referred by its `Id`.
