Trailer for Designing a database: From an idea to a relational data model
General Course Information
#Datenbanken #UML #Informatik #relationaleDatenbank #Modellierung #Normalformen #SQL
In this course, you'll find all kinds of stuff about databases - from modeling with UML to relation schemas and the quality of relational schemas and corresponding anomalies. Our content, such as videos, interactive books, PDFs, and more, is designed for everyone: pupils, students, and anyone else who is interested.
Dive into the world of databases, and learn content through stories! Animated characters explain the content and its use in concrete problem situations and take place in a police department and a local bakery and are always database-related. The contents span the entire design of a criminal and a bakery database and thus represent an essential part of the life cycle of a database. A good design lays the foundation for valuable and practicable databases and prevents problems!
The conceptual and logical design steps of this database are accompanied and attention is drawn to problems and anomalies of poorly designed databases and what determines good relational design. The idea behind this course is to get away from a typical teaching setting with recorded lectures towards more active learning and application of the taught knowledge. Videos are therefore underlaid with H5P elements to increase interactivity and consolidate knowledge right away. The associated tasks are also designed in an exciting way and embedded in stories. Help our two inspectors apply what you've already heard and show what you've got!

You can get a brief overview in the video above.
Structure of the course:
The MOOC is divided into several lessons - that's six informative steps into the world of relational databases:
Lesson 1: Overview of the MOOC's goals, content, and working methods
Lesson 2: Introduction to the world of databases
Lesson 3: Domain analysis and conceptual design (semantic data model)
Lesson 4: Extended conceptual design
Lesson 5: Design of a relational database (transformation to the relational model)
Lesson 6: Quality of relational schemas and normal forms
Note: The above learning time per lesson is estimated, and results if all topics and in-depth examples (tasks) are worked through entirely in the lessons. With appropriate prior knowledge, this can be significantly shortened. It is also possible to only take single lessons or single content). In this case, however, no certificate can be provided.
Course Goals
- Know the characteristics, architecture and data models of database systems.
- List phases of database development and briefly describe the necessary steps
- Design a database conceptually (using UML class diagrams)
- Derive a relation model from the database design
- Name guidelines for well designed relational schemas and briefly describe and fix anomalies occurring in non-normalized schemas
- Being familiar with the first three normal forms and being able to determine the normal form of a given scheme
Previous Knowledge
No special prior knowledge is required for this course. This excludes ordinary computer skills, as well as related software (including downloading and installing software) and using web applications.
Course Procedure
Each lesson starts by outlining the key content that will be covered in the lesson and questions that can be answered after the lesson is complete. If we suggest an exercise environment in a lesson, there is also detailed information about it before things get started. Depending on the scope, a lesson consists of one or more topics.
In this MOOC, we follow a particularly applied learning approach (with a fictional police department and bakery). Therefore, topics usually start with a practical question, which is intended as a challenge and should be able to be solved after working through the topic. If the necessary competencies are already available due to previous experience, this will become clear already at this point.
For each topic, we offer learning objects that convey basic knowledge about a topic (what I should know about the topic) or show the application of this basic knowledge by means of examples (application examples) and also tasks for applying what has been learned. These can be short videos (with characters from our police department), interactive books, or texts. The order of the learning objects is technically sequential but can be consumed as needed.
Each lesson concludes with a lesson quiz. 75% of the required points are necessary for the positive completion of the lesson (and the certificate at the end).
Certificate
For actively participating in the course you will receive an automatic certificate which includes your username, the course name as well as the completed lessons. We want to point out that this certificate merely confirms that the user answered at least 75% of the self-assessment questions correctly.

Claudia Steinberger, Nina Lobnig
This MOOC was funded by the bmbwf as part of the eInformatics@Austria project (Digital and Social Transformation in Higher Education, 2020-2024). The aim of the project is to develop MOOCs for teaching Computer Science Basics Online (1ngO) and this course covers part of the topic 'Databases and Logic', which was created by the project team from Klagenfurt.The main authors are Claudia Steinberger and Nina Lobnig, who were actively supported by their colleagues.
It is recommended to complete the MOOC on 'Databases: Discover the World of SQL' afterwards as it is designed as a follow-up course.
Sam Winter, Lara Fischer and Amar Kovač
Our fictional characters Sam Winter, Lara Fischer and Amar Kovač will guide you through the course, presenting the content both in theory and in practice as well as illustrating it with examples.
Sam Winter (pictured in the middle) is an expert in databases and introduces the various topics, explains all the important details and also demonstrates the content using examples. She often brings examples from her favorite bakery, which she supports in the implementation of a new database, as well as from the police department, with whom she also cooperates.
Lara Fischer (on the left) and Amar Kovač (on the right) are two police officers who exchange ideas with expert Sam. They apply the introduced knowledge in their daily work.
Contributors to the conception and production of the MOOC and its content (all coming from the University of Klagenfurt, listed alphabetically):
- Nicole Burgstaller
- Nina Lobnig
- Michael Morak
- Claudia Steinberger
- Claudia van der Rijst
- Anna-Sophie Wallner
- Aron Wedam
- Markus Wieser
- Andreas Bollin (didactic consulation)
