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.

  • The first character in an identifier must be a letter.
  • The last character in an identifier must not be a hyphen.
