- 01Describe the system in plain text
Write a concise prompt listing the key entities (e.g., User, Voucher, Redemption) and their relationships.
- 02Generate the initial class diagram
Let the tool convert your text into a UML class diagram with classes, attributes, methods, and associations.
- 03Refine the diagram
Adjust class names, add missing attributes, or change relationship types (association, aggregation, composition) as needed.
- 04Export and share
Download the diagram as PNG/SVG or share a live link with your team for collaboration.
Questions about uml class diagram templates
What are the main classes in an OTT voucher redemption system?
Typical classes include User, Voucher, RedemptionRecord, PaymentGateway, and Admin. The system often models relationships between users and redemptions, and between vouchers and their redemption status.
How do I model voucher status (e.g., unused, redeemed, expired)?
Add a status attribute to the Voucher class, often as an enum, and update it through methods like redeemVoucher() or expireVoucher().
Can I generate a class diagram from a text description?
Yes, ChatDiagram allows you to describe the system in natural language and automatically generates a UML class diagram that you can refine further.
What is the difference between aggregation and composition in this context?
Aggregation represents a 'has-a' relationship where the part can exist independently (e.g., a Voucher may exist without a RedemptionRecord), while composition implies a stronger ownership (e.g., a RedemptionRecord cannot exist without a Voucher).
