FAQ
Frequently Asked Questions
What is a domain model diagram?
A domain model diagram (also called a UML class diagram) shows the key entities in a system, their attributes, methods, and how they relate to each other. It is used in software design, business analysis, and database planning to align teams on the structure of a system before building it.
How does the AI domain model diagram maker work?
You describe your domain in plain English — mentioning the main entities and how they connect. The AI interprets your description and generates a complete class diagram with classes, typed attributes, methods with visibility, and UML relationship arrows. You can then edit everything manually to match your exact needs.
Can I create a UML class diagram without knowing UML syntax?
Yes. MakeCharts handles all UML notation for you. You use plain-language forms to add classes, members, and relationships, and the diagram renders the correct arrows, visibility symbols, and cardinality labels automatically. No UML knowledge required to get started.
What relationship types does the class diagram support?
The tool supports all standard UML relationships: inheritance, composition, aggregation, association, dependency, realization, link, and dashed link. Each renders with the correct arrowhead style, and you can add cardinality labels and optional relationship names to any connection.
Can I add stereotypes like Interface or Abstract to classes?
Yes. Each class in your domain model diagram can be tagged with a stereotype: Interface, Abstract, Enumeration, Service, or none. Stereotypes appear in guillemet notation ('«interface»') on the diagram, following standard UML conventions.
Is the domain model diagram maker free to use?
Yes, the core tool is free with no sign-up required. You can create and export class diagrams immediately. AI-powered generation is available on free accounts with limited credits. Paid plans provide more AI credits and advanced export options.
Can I export my class diagram as an SVG or PNG?
Yes. Once your domain model diagram is ready, you can download it as a high-resolution PNG for documents and presentations, or as a scalable SVG for use in design tools, websites, and technical documentation.
How do I add methods and attributes to a class?
In the class editor, click 'Add Member' on any class. Set the member name, type, and visibility (public, private, protected, or package). Toggle 'Is Method' to mark it as a method, then optionally add a return type and flag it as static or abstract.
Can I use this tool for database schema design?
Yes. Domain model diagrams are a natural fit for planning relational database schemas. You can model tables as classes, columns as attributes with data types, and foreign key relationships using association or composition arrows with cardinality labels.
Does it work for large diagrams with many classes?
Yes. The diagram view supports zoom and pan navigation, making it easy to explore large class diagrams with dozens of classes. You can enable zoom in the Interaction Settings panel and navigate the full diagram without losing readability.
