“[E]xisting books on design patterns take a catalog approach, where they show the individual design patterns in isolation. This approach is […] flawed, because you can't see

approach is […] flawed, because you can't see how the design patterns actually function in the real world. Most programmers learn by looking at computer programs.”

� Context– Research work started since my Ph.D. thesis

(2000–2003)– Pattern Trace Identification, Detection, and

– Pattern Trace Identification, Detection, and Enhancement in Java

• Theories, methods, and tools, to evaluate and to improve the quality of object-oriented programs by promoting the use of idioms, design patterns, and architectural patterns

Ptidej Tool Suite

� Requirements– Software tools

• Support the analysis of the implementation, design, and architecture of object-oriented programs

and architecture of object-oriented programs• Support the detection and introduction of patterns at

the code, design, and architectural levels
