About structures

ColdFusion structures consist of key-value pairs. Structures let you build a collection of related
variables that are grouped under a single name. You can define ColdFusion structures
dynamically.
You can use structures to refer to related values as a unit, rather than individually. To maintain
employee lists, for example, you can create a structure that holds personnel information such as
name, address, phone number, ID numbers, and so on. Then you can refer to this collection of
information as a structure called employee rather than as a collection of individual variables.
