Purpose of Modeling
Modeling captures essential parts of the
system. Dr. James Rumbaugh
Visual Modeling is modeling using standard
graphical notations

Software Modeling Language

• What is UML?
• UML stands for Unified Modeling Language
• A standard language notation for visualizing,
  specifying, constructing, and documenting a
  software design
• Uses concepts from
• Data Modeling (Entity Relationship Diagrams)
• Business Modeling (work flow)
• Object Modeling
• Component Modeling
• The Creators
• Grady Booch, James Rumbaugh, and Ivar Jacobson

Design Goals for UML

• Provide users with a ready-to-use, expressive
  visual modeling language so they can develop and
  exchange meaningful models.
• Provide extensibility and specialization
  mechanisms to extend the core concepts.
• Be independent of particular programming
  languages and development processes.
• Provide a formal basis for understanding the
  modeling language.
• Support higher-level development concepts such as
  collaborations, frameworks, patterns and
  components.
• Integrate best practices.

What UML is and is not?
IS
IS NOT

• Standard modeling language
• Defines a semantic metamodel

• Visual programming language
• A tool interface, storage, or run-time model
• A standard process
