Expressions & Transforms — Overview
Wherever Zetect has to derive one value from your data, it offers three Source types. Identity (or Account) copies a single attribute unchanged. Expression builds a value from a text template. Transform runs a small declarative program — a lookup, a decision table, a date reformat, a pipeline of steps — over your attributes. This guide explains expressions and every transform type, with a runnable example for each.
The three sources
| Source | What it does |
|---|---|
| Identity / Account | Uses one attribute directly. On attribute mapping the option is Identity; on account association it is Account. |
| Expression | A literal string or a template using ${attr} placeholders — for example ${firstName}.${lastName}. |
| Transform | A JSON definition evaluated by the Transformation Engine. Everything in the rest of this guide. |
