# An IVR with Neo4j and F# -- Part 2 A

### Modeling the IVR domain with algebraic data types

## Why am I doing this?

In part 1 I talked about getting started on my graph-based IVR system. I started with modeling the authentication sub-graph. I wrote some Cypher queries to build the graph in Neo4j. In this part I am going to talk about how I modeled the graph in F# using algebraic data types, namely discriminated unions and tuples.

This . . .
