What is an Enumeration in Mendix, and how does it help in maintaining data consistency?

Answer 1

An Enumeration in Mendix is an attribute that has a pre-defined list of string values. It allows users to select values from a dropdown or a radio button. Enumerations help maintain data consistency by ensuring that data values are chosen from a predefined set.
