Component Design
Displays the high level packaged structure of the
code itself.
 Dependencies among components are shown

Source code components
Binary code components
Executable components.
Some components exist at compile time, at link
time, at run times well as at more than one time.

Drexel University
Model a component
Illustrates the pieces of software, embedded
controllers and such that make up a system, and
their organization and dependencies.
 A component is implemented by one or more
Classes (or Objects) at runtime.

Architecture Design
Models the configuration of run-time processing
elements and the software components,
processes, and objects that live on them.
 Software component instances represent runtime manifestations of code units.
 The relation between software and hardware
 The ambiguity of the definition of “architecture
design”
