Record and Extensible Enumerations
Explore the concept of record enumerations, which define records with unique enumeration literals and fixed lists, and understand how to represent them in UML despite limitations. Discover how extensible enumerations allow adding new values while maintaining data integrity, crucial for modeling dynamic data in applications.

Record enumerations
A record enumeration defines a record type with a unique field designated to provide the enumeration literals and a fixed list of records of that type. In general, a record type is defined by a set of field definitions in the form of primitive datatype attributes, such that one of the unique fields is defined as the enumeration literal field and a set of operation definitions.
Unfortunately, record enumerations, as the most general form of an enumeration datatype, are not supported by the ...
