│  │Node 1 │ │Node 2 │        │  Type:  [HTTP▼]      │
│  │ HTTP  │ │Script │        │                      │
│  └───────┘ └───────┘        │  URL:   [_____]      │
│                              │  Method:[GET ▼]      │
│  ┌───────┐ ┌───────┐        │                      │
│  │Node 3 │ │Node 4 │        │  [Save] [Delete]     │
│  │ Delay │ │ Loop  │        │                      │
│  └───────┘ └───────┘        │                      │
└──────────────────────────────┴──────────────────────┘

Node Types:

CREATE TABLE Scenarios (
  id INTEGER PRIMARY KEY AUTOINCREMENT,
  name VARCHAR(255) NOT NULL,
  description TEXT,
  status INTEGER DEFAULT 0,
  workflowGraph JSON,
  createdAt DATETIME NOT NULL,
  updatedAt DATETIME NOT NULL
);

Future Enhancements (Optional)

While the current implementation is complete, the following enhancements could be considered in future iterations:

1. Visual Workflow Connections

   • Draw lines between nodes to show flow
   • Implement with libraries like react-flow or xyflow

2. Drag & Drop Positioning

   • Allow manual node repositioning on canvas
   • Save x/y coordinates in node data

3. Workflow Execution Engine

   • Backend execution engine to run workflows
   • Queue management for concurrent executions

4. Real-time Monitoring

   • Live execution status updates
   • Detailed execution logs per node

5. Workflow Templates

   • Pre-built workflow templates for common tasks
   • Template marketplace/library

6. Import/Export

   • Export workflows as JSON
   • Import workflows from files

7. Advanced Validation

   • Detect circular dependencies
   • Validate node connections
   • Required field validation

8. Version Control

   • Save workflow history
   • Rollback to previous versions
   • Compare versions
