Object-oriented Design

Course Description

The course addresses the principles of object-oriented design based on development of domain model. The role of design in broader context of information system developement is defined, together with the process of creating domain model from analysis specification. Basic building blocks of domain model are described, with the illustration of design principles applicable in the development of the model.

General Competencies

Students are introduced to principles and techniques of object-oriented design and familiarized with the role of the design in the software development process. They will be able to practically apply the skills learned on the demonstration of concepts on a case study, and through individual seminars.

Learning Outcomes

  1. define basic priciples of object design
  2. apply principles of object design in implementing IT systems of medium complexity
  3. describe basic building blocks of domain driven design
  4. use basic building blocks of domain driven design
  5. describe object-relational mapping problem
  6. develop object-relational mapper with the use of NHibernate framework
  7. apply techniques of test driven development
  8. define advantages of agile approach in building IT systems

Forms of Teaching


Classes are organized in two cycles. First is 7 weeks in duration with exam at the end, while the second is 6 weeks of classes with final exam at the end.


During classes there will be short ("blitz") tests


Student must independently devise and implement seminar that will present learned techniques of object design

Programming Exercises

Student must solve three home work exercises.
