Course abstract

The aim of the study course is to provide an idea of system modeling techniques that can be used to describe and analyse applications at all stages of development. The main focus is on the object-oriented modeling language UML (Unified Modeling Language) as well as the business process modeling language BPMN (Business Process Modeling Notation). By working with modeling tools and languages, students gain theoretical and practical knowledge of conceptual and process modeling.

Learning outcomes and their assessment

1.Knowledge: about the types and basic principles of systems analysis and modeling, UML and business process notations, as well as insight into other modeling languages - theory test.
2.Skills: read and create UML and business process diagrams - practical tasks.
3.Competences: using modeling languages and tools to perform independent system analysis - practical tasks, presentation.

Requirements for awarding credit points

The student must have completed at least 50% of the total number of practical tasks and written the final test.
Written practical exam, oral theoretical questions.

Description of the organization and tasks of students’ independent work

Each week a new practical task is assigned, which is evaluated with a specific number of points (2-10 points). Task completion term - 1 week. Students need to create diagrams by description: by textual description and pseudocode, transform the diagrams into code, independently develop diagrams on the chosen topic.

Criteria for Evaluating Learning Outcomes

Practical tasks are assessed in accordance with the assessment procedure specified in the practical task. The final mark of the study course consists of the cumulative assessment of the semester work, the assessment of the test and the exam:
final test 20%;
practical tasks 50%;
exam 30%.
The exam consists of:
practical task on the topics acquired in the study course (20% of the total mark);
three oral theoretical questions about the completed task (10% of the total mark).

Students for whom the cumulative assessment of practical tasks and tests received during the semester is at least 80% of the maximum possible number of points may be exempted from the exam. The final grade is calculated based on the points obtained by the student (final grade 8-10).
