Objective: Combine two separate data streams into one list.

• Nodes Used: When clicking "Execute Workflow" → Stream A / Stream B → Merge (Append)
• Concept: Use the Merge node in Append mode to stack items from two inputs into a single list.
• Exercise Steps:
  • [ ] Create a new workflow named Lab 7 - The Merger.
  • [ ] Add a Manual Trigger node and rename it to When clicking "Execute Workflow".
  • [ ] Add a Set node called Stream A and set:
    • Source = Database A
    • Data = Adil Hidayat
  • [ ] Add a Set node called Stream B and set:
    • Source = Database B
    • Data = Pendakwah Teknologi
  • [ ] Add a Merge node called Merge (Append).
  • [ ] Connect When clicking "Execute Workflow" to both Stream A and Stream B.
  • [ ] Connect Stream A to input 1 of Merge (Append) and Stream B to input 2.
  • [ ] In Merge (Append) set Mode to Append.
  • [ ] Execute the workflow and confirm the Merge (Append) output contains two items, one from Database A and one from Database B.
