UML class diagram
A UML class diagram is a standardized structural model representing classes, their attributes and operations, and relationships such as inheritance, association, aggregation, and composition.
Data-Oriented Programming: Reduce software complexity
A UML class diagram is a structural diagram that represents classes, their attributes and operations, and relationships between them.
- How it is used
- Uses a pre-coding map to identify system classes, relationships, and potential design complexity.
- How deep it goes
- Explains four relationship types and applies them to a library system, then assesses complexity through relation counts.
- Examples
- Uses a library-management diagram containing Library, Member, Book, Author, Catalog, and BookLending relationships.
- What you can do after
- Evaluate a proposed object-oriented design by reading relationship notation and locating highly connected classes.

Functional Design and Architecture: Examples in Haskell
A UML diagram that represents classes, interfaces, implementations, and relationships in an object-oriented system.
- How it is used
- Communicates object-oriented design ideas and relationships before implementation.
- How deep it goes
- Represents high-level domain organization, stopping short of detailed implementation mechanics.
- Examples
- Uses an engine control subsystem containing ISubsystem, Engine, ControlPanel, and Status.
- What you can do after
- Evaluate and communicate object-oriented structures before coding.

Software Design for Python Programmers
A UML class diagram is a standardized graphical model that represents classes, their members, and relationships such as aggregation and composition.
- How it is used
- Documents class design and communicates application structure during iterative design, coding, and testing.
- How deep it goes
- Explains notation, visibility, signatures, detail levels, and class relationships, while stopping short of formal diagram construction procedures.
- Examples
- Uses Catalogue and Attributes diagrams, including progressively detailed compartments and a private static method.
- What you can do after
- Evaluate class structure and runtime relationships using appropriately detailed diagrams.
