Identifier¶
An identifier is a word or a few words that uniquely describe an object. Identifiers are often used instead of a database id due to their readability and portability.
Syntax¶
Identifiers are composed of lowercase alphanumeric characters and hyphens.
abcdefghijklmnopqrstuvwxyz1234567890-
- The first character in an identifier must be a letter.
- The last character in an identifier must not be a hyphen.
Examples¶
