Study Notes
Introduction
-
Models are representations of reality to simplify it
-
Models help in solving problems and experimenting with multiple solutions
-
Models reduce development costs and time waste
-
Models allow for easier product development and resource allocation
-
Models provide a number of views of the system
-
Unified Modeling Language (UML) is a visual modeling language that helps system developers to create blueprints in a standard and easily understood form
-
UML captures system vision in a standard and easily understood form
-
UML gives a mechanism to effectively share and communicate system visions with others
-
The Object Management Group (OMG) defines UML as a graphical language for specifying, visualizing, constructing and documenting the artifacts of the software system
-
UML is a language, not a notation system, with a predefined structure and a repository for the different notations
Features of UML
- Syntax-only language to define model elements, usage, and diagrams
- Comprehensive, able to model various systems
- 13 diagrams, allowing different perspectives of the system; use cases not required
- Language-independent, no binding to a particular high-level language, thus usable across tools or languages
Need for UML
- UML is a modeling language, not a notation system
- UML has predefined structure and repository for different notations used, similar to a structured language like English
- UML is process and method independent
- Uses object-oriented techniques and iterative development lifecycles
- UML is not difficult to learn in entirety; there's no need to know every detail
UML is Not
- UML is not a notation
- UML is not owned by anyone
- UML is not a process or method
- UML is not complex to learn in entirety
- UML is not limited to specific concepts, terms, and domains; it's flexible.
Self-Study and Reading Suggestions
- Provided with the book titles Unified Modeling Language User Guide and UML 2 For Dummies as learning resources.
