// Comprehensive Data Generation Script
// This script deletes all existing data, creates JobTypes from the provided list,
// generates multiple Job instances for each type, and wires them into different scenarios.

// 1. Clean up the database
MATCH (n) DETACH DELETE n;

// 2. Create Indexes
CREATE INDEX ON :JobType(id);
CREATE INDEX ON :Job(id);
CREATE INDEX ON :Scenario(id);

// 3. Create JobType Nodes from the provided examples
