Volume 2021/2022
Education

BSc Programme in Computer Science and Economics

Content

This course introduces students to basic database concepts such as relational databases, normal forms, and transactions. In addition, the course covers system development (basic software development) and version control, and includes the practical development of a smaller system (web system, mobile system, or the like, which must be decided before the course starts) as project work.

Learning Outcome

Knowledge of

  • Key database technical concepts such as the relational model, data independence and transactions.
  • Entity-relationship modeling (ER modeling) and relational data modeling, including transformations from ER modeling to relational data modeling.
  • Queries in database query languages, including both relational algebra and SQL.
  • The theory of database normalization, including functional dependencies, keys, and relational decompositions.
  • ACID (atomicity, consistency, isolation, durability) properties and use of transactions.
  • Indexing techniques and their role in database query optimization.
  • Use of constraints and triggers.
  • Facilities for connecting databases, programming environments, and program libraries.

 

Skills in

  • Developing a data model and realizing database applications starting from the ER modeling, over relational modeling and normalization, to concrete relational, SQL-based database application.
  • Planning and managing an agile, iterative, and learning-oriented system development process, which under given resource and time constraints leads to the realization of a new database application.

 

Competence in

  • Developing a database design and implement database applications.
  • Effectively participating in an agile software development process as part of a group of developers.

See Absalon when the course is set up.

Programming skills and experience in software development at a level corresponding to the completion of the DIKU courses "Programming og problemløsning" and either "High Performance Programming and Systems" or "Computer Systems”.
A combination of lectures, exercise sessions and a practical group project (with report).
The course is identical to the discontinued course NDAB20003U Databaser og informationssystemer (DoI). Therefore you cannot register for NDAB21010U - Databases and Information Systems (DIS), if you have already passed NDAB20003U Databaser og informationssystemer (DoI).
If you are registered with examination attempts in NDAB20003U Databaser og informationssystemer (DoI) without having passed the course, you have to use your last examination attempts to pass the exam in NDAB21010U - Databases and Information Systems (DIS). You have a total of three examination attempts.
