and extended relational algebra. Then we will introduce concepts
needed for designing good relational databases. We will start on
functional dependencies, decomposition of relations, and normal
forms.

Chapters 3.1-3.3
Lecture 2
The fifth lecture will continue with normal forms and introduce the
third normal form (3NF). In the second half we will start on entity

Exercises
Time to get your hands dirty! This exercise will take place in IMADA's
terminal room. You should get an account for the database server and
set up a test database with the running examples from the lectures.
Try some of the queries from the lecture on this test database. Then
add some relations from the previous exercises and perform queries
on them.
