Sequence: A Sequence is the most basic type of workflow in UiPath. It represents a linear set of activities executed one after another. Each activity is executed in the order it appears in the workflow. Sequences are useful for building simple and straightforward automation processes where the activities need to be executed in a predefined order.
Use Cases:
Data entry tasks that require filling out forms in a specific sequence.
Basic data validation and manipulation operations.
Simple decision-making processes.
Flowchart: Flowchart workflows provide a graphical representation of complex business processes. They enable branching, looping, and decision-making capabilities, making them highly versatile for handling complex logic and exceptions. Flowchart workflows consist of activities connected by connectors, allowing the flow of control to change dynamically based on conditions.
Use Cases:
Complex decision-making processes involving multiple conditions and branches.
Workflows with conditional loops and iterative tasks.
Business processes with exceptional handling requirements.
State Machine: State Machine workflows are specifically designed to model systems that transition between different states. They are ideal for scenarios where an automation process needs to switch between various states based on specific triggers or events. State Machine workflows consist of states, transitions, and triggers, providing a structured way to represent complex processes with multiple states and conditions.
Use Cases:
Order processing workflows with different stages (e.g., pending, processing, completed).
Application workflows with distinct states (e.g., login, data entry, logout).
Systems with conditional branching based on states and triggers.
Global Exception Handler: The Global Exception Handler workflow is a specialized workflow that handles exceptions and errors occurring during the execution of other workflows. It provides a centralized location to handle exceptions, log errors, and perform specific error recovery actions. By using the Global Exception Handler, you can streamline error management and improve the maintainability of your automation projects.
Use Cases:
Centralized error handling and logging for multiple workflows.
Consistent exception handling across automation projects.
Custom error recovery actions based on specific exceptions.
