Principles of Software Construction Objects, Design, and Concurrency


Software engineers today are less likely to design data structures and algorithms from scratch and more likely to build systems from library and framework components. In this course, students engage with concepts related to the construction of software systems at scale, building on their understanding of the basic building blocks of data structures, algorithms, program structures, and computer structures. The course covers technical topics in four areas: (1) concepts of design for complex systems, (2) object oriented programming, (3) static and dynamic analysis for programs, and (4) concurrent and distributed software. Student assignments involve engagement with complex software such as distributed massively multi-player game systems and frameworks for graphical user interaction.

After completing this course, students will:


Tu/Th 9:00 - 10:20 a.m. in DH 2210

Professor Charlie Garrod
WEH 5101
Professor Jonathan Aldrich
WEH 4216

Both instructors have an open door policy: If either of the instructors' office doors are open and no-one else is meeting with us, we are happy to answer any course-related questions. For appointments, email the instructors.

Course Syllabus and Policies

The syllabus covers course overview and objectives, evaluation, time management, recommended books, late work policy, and collaboration policy.

Learning Goals

The learning goals describe what we want students to know or be able to do by the end of the semester. We evaluate whether learning goals have been achieved through assignments and exams.
