By the end, you&#8217;ll see how use cases drive structural design: nouns from flows (Book, Member, Loan\u2026) become classes; modules become components; and runtime nodes show deployment.

We&#8217;ll start with the domain model using a Class Diagram (generated via AI and refined manually), then build a simple Component Diagram manually, and finally create a Deployment Diagram that reuses components from the previous step. By the end, you&#8217;ll see how use cases drive structural design: nouns from flows (Book, Member, Loan\u2026) become classes; modules become components; and runtime nodes show deployment. Generating a Class Diagram (Domain Model) with AI Visual Paradigm&#8217;s AI can quickly draft a domain-focused class diagram from a description \u2014 perfect for bootstrapping from use cases.
