Entry knowledge
To study database systems, basic knowledge of algorithm development is sufficient.
Rules for evaluation and completion of the course
A condition for credit is the implementation of a non-trivial database application using appropriate resources.
The exam is written or electronic. Students demonstrate knowledge of data structure design, relational algebra, SQL and programming.
As the exercises are compulsory, the instructor will check attendance at regular intervals. In case of an excused absence, the student will be given examples to work on independently so that he/she can master the missed material.
Aims
The aim of the course is to introduce students to basic database technologies for effective design and management of applications with large amounts of data in the Internet environment.
The course is designed to introduce students to the theoretical aspects of database application design and implementation in an Internet environment, including the programming techniques involved. They will be able to create an application for efficient management of large amounts of data and also learn how to use cloud services.
