Unified Modeling Language (UML)

UML (Unified Modeling Language)

● UML is a language for the standard model development of software blueprints. 

● Language is the language models have a dictionary of words and rules-based the conceptual and physical picture of a system 

● UML as the language of the model states how to make and read a model correctly, but does not state the model what to make and when should made

Role of UML 

UML is a language for 

● Visualization 

- Describing the ideas in notation and semantics more easily understood by anyone 

● Specifications 

- Specification of all important decisions analysis, design, and implementation should be taken in the development and deployment of software systems

● Construction 

- UML is not a visual programming language 

- UML models can be connected directly with several programming languages 

- Forward engineering: generating code from models 

- Reverse engineering: building a model of the code 

● Documentation 

- UML includes documentation and system architecture detailed 

- For a language to express needs and testing. 

- UML provides a language for planning activities project and release management

Structural Things

● Structural thing is a noun models UML 

- Class 

● An overview of a set of objects that share attributes, operations, relationships and semantics are the same 

● A class implementing one or more interfaces 

- Interface 

● A set of operations stating the services of a class or component 

● An interface describes the behavior of objects provided to outside parties. 

● Interface can only declare some or all the behavior of a class / component.

● Collaboration 

- An interaction and a set of rules and elements others who work together to provide behavioral working together 

- Declare the application of pattern forming systems 

● Use Case 

- An overview of a set of action sequences occurs in a system that produces a value the actor 

- Used to menstrkturkan system behavior in a model 

- It is the realization of collaboration.

● Active Class 

- A class to which the object has one or more process / thread activity so that it can start controls 

● Component 

- A physical and replaceable part of a system provides the realization of a set of interfaces 

- Declare the physical package than logic elements, such as classes, interfaces and collaboration 

● Node 

- Physical elements that exist at run time and expresses a sesumber calculations, which memory and processing capabilities
