objectives
- solve common design problems without recreating
the wheel
- tap into a wealth of collected knowledge on
software development
- use patterns at every stage of software development:
architecture, design, and implementation
- understand what does and does not go to make
up a pattern
- understand the beneficial role of patterns in
all aspects of development
- learn and use common patterns for object-oriented
and large-scale design
- appreciate patterns from the strategic level
down to idiomatic examples in Smalltalk
overview
Nontrivial systems include many recurring design
problems whose solutions are commonly repeated
from place to place, and from programmer to programmer.
The essence and basic structure of a solution
may be repeated many times, even though the realization
is different in each case.
Patterns offer a technique for capturing design
and architecture, presenting and communicating
architectural knowledge at all levels of a system,
allowing experience to be understood and distilled.
Patterns allow developers to work on and
understand designs, and are not a basis for automation
of design. This course introduces patterns
from the ground up, presenting principles as well
as concrete examples in UML and Smalltalk.
It develops understanding through lectures, discussion,
and some exercises to reinforce the concepts by
putting them into practice.
The course is suitable for software developers
and designers familiar with Smalltalk.
The course is presented by one of our senior
consultants, each of whom has at least ten years'
experience in software development, and at least
three years' experience as a trainer and consultant
in a diverse range of application areas.
