Design Patterns in Software Design
Students are trained to apply key design principles in planned construction of high quality software subsystems. These information enable critical assessment of different solutions to the problem at hand in software design. The presented patterns offer an in-depth view onto common organizational challenges in software design, as well as a pragmatic insight into advantages of novel features of modern programming languages. By employing the acquired knowledge and practical experience, the students will be able to improve the organization of their software systems, as well as to clarify documentation through usage of established pattern terminology.
- recognize symptoms of inadequate software design
- discuss advantages of dynamic polymorphism, templates, and duck typing
- explain the major principles of software design and recognize cases of their violation
- evaluate the quality of multiple software designs based key design principles
- recognize different design patterns in uncommented code
- select and apply appropriate design patterns in the construction of a software product
- compare the adequateness of different design patterns in the context of a given design problem
- apply design principles for conceiving high-quality software components
