The course covers the basic principles of database systems as seen by users, application programmers and database administrators. A laboratory assignment develops these topics as a running example throughout the course. These include programming in SQL, as seen by a user querying or modifying an existing database, by a database designer, and by an application programmer invoking SQL from a host language. Course contents include:
- Database querying and manipulation through SQL
- Entity-Relationship modelling
- Functional dependencies, normal forms, and relational algebra
- Interfacing to a database from a host language (Java/JDBC)
- Altenative data models: XML, JSON, NoSQL
The course is thus a typical first course in database systems, and occupies a traditional place in the curriculum.

The course has following components:
- programming assignment ("lab")
- supervised work in programming class ("labs")
- course literature
- discussion group
Only the programming assignments and the exam are compulsory.
Changes made since the last occasion
No significant changes since last year.
Written exam, individual
Programming assignment, in groups of two, four parts
Learning objectives and syllabus
On successful completion of the course the student will be able to:
Knowledge and understanding
- explain the semantic meaning of queries using relational algebra
- describe the effects of transactions and indexes in a relational database
Competence and skills
- construct an Entity-Relationship diagram for a given domain
- translate an Entity-Relationship diagram into a relational database schema
- apply design theory concepts for relational databases such as functional dependencies and normalization
- retrieve and modify data using a database language for respective task
- design a database interface using constraints, views, triggers and privileges
- implement a relational database schema and related interface using a data definition language
- communicate with a database, through a database interface, from a software application
Judgement and approach
- evaluate and create different models for a database domain using EntityRelationship diagrams and relational schemas
- contrast different data models, such as the relational and the semi-structured data models
