Tutorial: AI Base Use Case Diagram Analyzer

Introduction

The AI Base Use Case Diagram Analyzer is a tool designed to simplify and enhance the analysis of use case diagrams, which are essential for visualizing system functionality and actor interactions. This tool automates the process of breaking down complex diagrams, providing clarity, efficiency, and actionable insights for software design and collaboration.

Key Concepts

1. Use Case Diagrams

• Definition: A use case diagram is a UML (Unified Modeling Language) artifact that represents the interactions between actors (users or external systems) and the system’s functionalities (use cases).
• Purpose: Helps stakeholders understand system requirements and boundaries.

2. PlantUML

• Definition: A text-based language for creating UML diagrams. PlantUML code can be used to generate use case diagrams programmatically.
• Example:
  plantuml

  Copy

  @startuml
actor User
User -> (Login)
User -> (Logout)
@enduml

3. Core Features of the Analyzer

• Core Clarity: Summarizes essential interactions between actors and use cases.
• Focused Discovery: Allows users to focus on individual actors and their roles.
• Efficiency Boost: Reduces manual effort in tracing and documenting relationships.
• Streamlined Collaboration: Generates easy-to-read diagrams for non-technical stakeholders.

Step 2: Input Your PlantUML Code

1. Paste or Load PlantUML Code:

   • Copy your PlantUML use case diagram code.
   • Paste it into the analyzer’s input field.
   • Alternatively, load a file containing the PlantUML code.

2. Example PlantUML Code:

   plantuml

   Copy

   @startuml
actor Customer
actor Admin
Customer -> (Place Order)
Customer -> (View Order History)
Admin -> (Manage Inventory)
Admin -> (Generate Reports)
@enduml

Step 3: Generate a Relationship Summary

1. The tool automatically parses the PlantUML code.
2. It generates a high-level summary of all actors and their associated use cases.
3. Example Output:
   • Actors: Customer, Admin
   • Use Cases for Customer: Place Order, View Order History
   • Use Cases for Admin: Manage Inventory, Generate Reports

Step 4: Generate Focused Sub-Diagrams

1. Select an actor (e.g., Customer).
2. The tool generates a simplified sub-diagram showing only the selected actor and their interactions.
3. Example Sub-Diagram:

Step 5: Export and Share

1. Copy the PlantUML code for the sub-diagram.
2. Share it with team members or integrate it into other documents.
