UML/rose learning notes Series II: UML Conceptual Model

Three main elements of modeling:

1. Basic Construction blocks of UML;

2. Rules on how to put these constructor blocks together;

3. Some common mechanisms applied to the entire UML;

The UML constructor consists of three types: A, thing B, relationship C, and diagram.

Things: including "structured things", "behavior things", "grouping things", and "commenting things ";

"Structured thing": Class, interface, collaboration, usage, active class, component, node;

"Action thing": interaction and state machine;

"Group thing": package;

"Annotation": annotation;

Relationship: includes "dependency", "association", "General Relationship", and "implementation relationship ";

Figure: including "class diagram", "Object diagram", "usage diagram", "sequence diagram", "Collaboration diagram", "State Diagram", "activity diagram", and "component diagram", "Implementation diagram ";

UML rules

UML has semantic rules used to describe the following things:

Name: the transaction, link, and graph name;

Scope: give a name a specific context;

Visibility: How to make others use or be visible;

Integrity: How Things interact correctly and consistently ;;

Execution: what is the meaning of running or simulating a dynamic model;

Common mechanism in UML

1. Details

2. Modify

3. General Division -------> A: Division of classes and objects B: Division of interfaces and Implementations

4. Expansion Mechanism -------->: A: constructor B: labeled C: Constraint
