Study Guide

Objective

The students know the principles of relational databases, can design and implement a simple database, know how to use relational database software and a completed database in the query language.
After the course the students will understand the central role of databases in information systems. The students will also understand the growing importance of databases with the growth and improvement of hardware, software and data transfer capacity. Key operating environments include WWW, electronic commerce, data generated by sensor networks, the Internet of Things and mobile environments.
