Reactive and Event Based Systems (REB)

Course content

In this advanced course, you will get the chance to learn about the basics of reactive and event-based systems, as well as research-based technologies for implementing reactive and event-based systems with applications in various areas such as business process management systems, large scale data processing and distributed systems, games, robotics, and IoT.

Concretely, the course will introduce you to three active research topics at DIKU with applications in industry that can serve as a basis for a bachelor project: 1) Declarative Process Models and Event-Based systems, 2) Actors and databases, 3) Event stream processing.

Learning outcome

Type of assessment
Oral examination, 20 min
At the exam the student will be asked to give a prepared presentation (8 min) of one of the mandatory assignments, decided at random at the exam. The students are allowed to collaborate in the preparation of presentations of assignments. After the presentation the student will get questions to the presentation and in general within the entire course curriculum.
Aid
Written aids allowed

The student is allowed to bring notes, laptop with the assignments (to make demonstrations) and a prepared presentation of each mandatory assignment. 

Marking scale
7-point grading scale
Censorship form
No external censorship
Criteria for exam assessment

The grade will be based on the ability at the exam to demonstrate the achievement of the goals given in the course description. In particular, it is required that the student can explain the assignments and argue for choices made in the assignments.
