Building Workflows
In Data-River, building workflows is all about connecting visual blocks to define the flow of data and actions. Whether you're automating a business process or creating a simple logic flow, Data-River makes it easy with a drag-and-drop interface.
This guide introduces the key concepts of building workflows using the basic blocks—Start, Input, Output, and End. Each block has a specific role in your workflow, and by connecting them, you can create a powerful automation system.
Key Blocks for Building Workflows
When starting out with Data-River, you'll primarily work with these four blocks:
1. Start Block
The Start Block is essential for every workflow. It initiates the flow and signals the beginning of the process.
Purpose: Initializes the workflow.
Example: Starting a workflow, that fetches pokemon information.
2. Input Block
The Input Block is used to collect data that will be processed in your workflow. This could be user input, API data, or information from another service.
Purpose: Collect data for use in the workflow.
Example: Providing an pokemon name to a workflow that fetches the pokemon's information.
3. Output Block
The Output Block is where the results of the workflow are displayed or passed to another system.
Purpose: Displays or outputs the results of the workflow.
Example: Outputting a pokemon's information to the user.
4. End Block
The End Block marks the conclusion of your workflow. Once this block is reached, the workflow is complete, and no further actions will be taken.
Purpose: Signals the end of the workflow.
Example: Finalizing workflow execution and displaying the results.
How to Build a Workflow
Building a workflow in Data-River is simple:
Drag and Drop: Select blocks from the block library and drop them onto the canvas.
Connect: Link the blocks by dragging from the output of one block to the input of another.
Configure: Customize the blocks by setting input values, defining outputs, and configuring any necessary parameters.
Test and Run: Once your workflow is set up, run it to see it in action.
For example, to build a simple workflow that collects a user’s name and outputs a greeting:
Start with a Start Block.
Add an Input Block to enter pokemon name.
Connect the Output Block to display the pokemon information.
Finish with an End Block to complete the flow.
Best Practices for Building Workflows
Start Small: Begin with a basic workflow using the Start, Input, Output, and End blocks. Once you're comfortable, you can add more complexity.
Organize Your Workflow: Keep your workflows tidy by arranging blocks logically.
Test Frequently: Test each block as you go to ensure everything is working as expected before adding more steps.
