This course extends object-oriented analysis and design by incorporating design patterns to create interactive applications. Through a survey of established design patterns, you will gain a foundation for more complex software applications. Finally, you will identify problematic software designs by referencing a catalog of code smells.
You will be challenged in the Capstone Project to redesign an existing Java-based Android application to implement a combination of design patterns. You will also critique a given Java codebase for code smells.
After completing this course, you will be able to:
• Demonstrate how to use design patterns to address user interface design issues.
• Identify the most suitable design pattern to address a given application design problem.
• Apply design principles (e.g., open-closed, dependency inversion, least knowledge).
• Critique code by identifying and refactoring anti-patterns.
• Apply the model-view-controller architectural pattern.
Overview
Syllabus
- Introduction to Design Patterns: Creational & Structural Patterns
- Design patterns help to solve common design issues in object-oriented software. You will learn what they are and how they can be applied. In this module you will learn the creational and structural design patterns. You will continue to learn and practice expressing designs in UML, and code some of these patterns in Java.
- Behavioural Design Patterns
- You will continue learning useful design patterns and add them to your toolbox. In this module, you will learn the behavioural patterns. This will include communicating them in UML and coding them in Java!
- Working with Design Patterns & Anti-patterns
- You will learn a design pattern that is very useful for user interfaces: model-view-controller, or MVC. Then you will learn some principles underlying the design patterns, to create software that is flexible, reusable, and maintainable. Finally, you will learn some of the symptoms of bad design, which we call code smells or antipatterns.
- Capstone Challenge
- In the previous modules, you were introduced to a variety of design patterns, and applied two of these to the example Android code base. Now, in the final module of the course, you will identify and fix specific code smells in this code base. After completing these tasks, you will be ready to complete the final exam.

Content is ok for a beginner. Usually it just scratch the surface and doesn't go in great detail.
Exercises quality is quite poor. Many errors in the UML diagrams and code examples. -
Sylvain KouemoI started the specialization of this course, for software architecture, it's a very amazing course, well done with the maximum of information for the student -
The course was great and really helpful... Just 1 problem I have faced a lot is the programming language, I don't have experience in Java, and setting up the environment for Java and giving assignments in Java was very difficult for me.

Nice course for beginners. It teaches the base for start learning patterns.
Som explaniations are superficial and are not so clear and it is hard to understand I recommend take notes and read the transcription to understand better.
Something I hate are the Peer rewiew excersises because almost the 80% of them are plagarism and doesn't give a real feedback. -
The Design Pattern Course Content is really understandable. The assignments helps to learn by experiencing design topics. I enjoyed the lesson very much. I recommend
the course to every Software Engineer. -
very good course which covers many aspects of design patterns in good depth. it would be even better if it covered all other patterns.
-
I think it lacked a little more practical examples. Other than that, the course is very complete and interesting.
-
This is an excellent course for the individuals who are seeking to advance career in programming because design patterns are the flavor of programming and the code smells if it does not have patterns implemented.
So I would recommend everyone to take this course. -
Stefan KarschtiIt's a very good course to take if you're specializing in software architecture or just formalizing your specialization. The course details the most used design patterns then follows up with assignments and quizzes. I am very satisfied having taken this course. -
Design pattern is really useful for any developer in the world .it facilitate problem's design and make avoid some code smells to be the code flexible reusable and maintainable.
-
Not a complete catalouge of DPs but explains the underlying principles behind the major categories. Exams and exercises are good for practice.
-
Good course even if you know the basic design patterns.
My only wish is that the course could have covered all the design patterns in the GOF pattern list which are used in day to day softwares (eg Builder pattern)
Also I think one should not enforce knowledge of android for design pattern. -
Cassiano Reinert Novais Dos SantosGreat course to a general view of Design Patterns. I could get really a good understanding.
The instructor are very direct and concise with great examples to make us understand.
I recommend it for anyone searching for an online course in Design Patterns and Software Architecture.
Thank you! -
Very good course, well balanced between theory and practice.
I recommend it if you want to understand how to structure SW applications.
This is my second course in the Coursera SW Design and Architecture specialization, and after having completed it, I decided to continue with the next one. -
I really enjoy this course. All information is useful and interesting. You will get really essential skills for software development after completing this course. Material is quality and assignments are really helpful. Thanks to the creators!
-
I really enjoyed this course. While I have been familiar with design patterns for several years, and actively use them in my work, this course helped me solidify my understanding, and provided new perspectives on these ideas. Very useful.
-
Konstantinos EfkarpidisIn my opinion this course is really good start to design patterns if you are new. Before the course i had no idea what design patterns are , but now i consider that this course covered a big variety of them. -
Not all the essential design patterns and refactoring techniques have been discussed, but it's still really good. I also liked the way the assignments were structured.
-
I like this course and specialization. I have learned so much. It’s useful for apply in my job. I recommend this course and all of the course of this specialization.

Md. Golam HossainNice and precise coursemap to rewind design patterns learning gathered in university. More exercise could be added though. Loved the course nevertheless.
