Course purpose

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.

Course literature

  • Jyrki Nummenmaa and Aarne Ranta: Databases in 144 pages (free PDF), lecture notes (a book in construction).

Further reading (was the course book before):

  • Hector Garcia-Molina, Jeffrey D. Ullman, and Jennifer Widom, Database Systems: The Complete Book, Pearson Education, 2014 (1133 pages).
    Book web page. Paper copies and eBook available in the Chalmers Library.

Course design

The course has following components:

  • lectures
  • exercises
  • programming assignment ("lab")
  • supervised work in programming class ("labs")
  • course literature
  • discussion group
  • exam

Only the programming assignments and the exam are compulsory.

Changes made since the last occasion

The contents of the course is the same as last year. There will be some minor changes in the labs and the lectures to stay in sync with the lp2 HT2019 edition of the course.

Examination form

  • Written exam, individual. There is a separate page for more info about the exam.
  • Programming assignment, in groups of two, four parts.

Learning objectives and syllabus

Learning outcomes

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
