2. Topics Software architecture Architectural patterns
Enterprise architectures
CS427 - lecture 1

3. Software Architecture
Software Architecture in Practice, by Len Bass, Paul Clements, and Rick Kazman
Software Engineering Institute view on software architecture
How architectures influence and are influenced by the organizations that create them and the systems they are part of.
CS427 - lecture 1

4. Software Patterns
Pattern-Oriented Software Architecture: A System of Patterns by Buschmann, Meunier, Rohnert, Sommerlad, Stal
Architectural patterns, design patterns, and idioms
Architectural patterns are similar to architectural styles in SAIP

5. Enterprise Architecture
Patterns of Enterprise Application Architecture by Martin Fowler et. al.
How to build large OO business systems
51 patterns
Applicable to Java, .NET, Smalltalk, etc.
CS427 - lecture 1

6. Enterprise Solution Patterns Using Microsoft .NET

A lot like Patterns of Enterprise Application Architecture, but explaining how to apply to Microsoft platform

7. Schedule First week Next thirteen weeks presentations by me
Half-hour presentations by students on each chapter
you must read each chapter BEFORE the talk
project and essays
discussion
CS427 - lecture 1

8. Schedule for presentations
At least a week before presentations, the presenter will post a few questions
At least a day before presentations, each person will answers to the presenter, no more than a page in length.
Presenters can use this to determine what to talk about.
Presenters grade answers
CS427 - lecture 1

9. Example Questions
SAIP 2: Compare and contrast software architecture with building architecture.
SAIP3: What is an architectural question you have about the A-7E that the chapter did not answer?
SAIP 4: Which qualities are most important? Which one is hardest to understand?
CS427 - lecture 1

10. Features of good questions
Answers can be short
Answers don’t require graphics
Must read chapter to answer questions
Answers let presenter know which part of the chapter should be emphasized
CS427 - lecture 1

11. Grades on Answers 3 - Outstanding answer
2 - Good answer, read the chapter and generally understood it
1 - Did you read the chapter? If so, you didn’t understand it very well
Can miss 5 answers
CS427 - lecture 1

12. Project Work in groups of 4-8 people.
Build an electronic stock exchange using patterns in the class.
J2EE, .NET, or Smalltalk
Compare the resulting systems
CS427 - lecture 1

13. Grade 25% - project 20% - presentation 15% - answers on chapters
20% - essays
10% - pattern
5% - course summary
5% - class participation

14. Patterns Things that repeat Architectural patterns
styles like “three tier client/server”
designs like “parser/lexer/symbol table/analysis/code generation”
processes like “architect also implements”
CS427 - lecture 1

15. Patterns Best practices: copy other people
Techniques: enlarge your tool box
Vocabulary: language for discussing architecture
CS427 - lecture 1

16. Patterns Christopher Alexander - architecture theory Contributions
The Timeless Way of Building
A Pattern Language
Contributions
balance of forces
problem/solution
pattern language
piecemeal growth
CS427 - lecture 1

17. Design Patterns
Design Patterns: Elements of Reusable Software by Gamma, Helms, Johnson, and Vlissides
First book on patterns of software
Low-level object-oriented patterns
CS427 - lecture 1

18. Finding patterns Look at things Notice similarities
Why does this similarity exist? What problem does this technique solve?
CS427 - lecture 1

19. Assignment
Go to class wiki (wiki.cs.uiuc.edu/cs427) and make a home page for yourself. Put your address on it. Add a link to it from the class list.
