Formelle forudsætninger:This course assumes basic ability to use a computer. We also assume that a student is taking an introductory programming course in parallel (otherwise basic programming skills in Java are expected) and following a discrete math course such as SGDM (or has knowledge of basic discrete math (logic, set theory and proofs)). 
Læringsmål:* suggest a database design according to the relational model, and present it as an SQL schema, using the concepts key, type, and constraint.
* define a database design by E-R modelling, using the concepts entity, attribute, key, cardinality, and relationship.
* analyze and improve database designs using normal form theory
* write SQL queries, involving multiple relations, compound conditions, grouping, aggregation, and subqueries.
* find functional dependencies in a relation and perform decomposition to eliminate unwanted dependencies.
* decide if a given index is likely to improve performance for a given query.
* identify possible problems in transaction handling, related to consistency, atomicity, and isolation.
* analyze/predict/improve efficiency of the designed database using indices
* use SQL from other programming languages.
* suggest a conceptual and physical design of an OLAP system. 
Fagligt indhold:The course gives an introduction to relational databases as well as an introduction to data analytics, both from a practical and theoretical point of view.

The main part of the course deals with relational databases, including theory and practice for modeling and quering a database. Towards the end of the course the focus will be on techniques for OLAP.

For relational databases the following topics will be covered:
• Programming in SQL, including all basic operations as well as some more advanced constructions (e.g. subqueries)
• Database design using E-R modelling
• Defining a database design using the relational model and SQL schemas
• Normalization of relations
• Use of different indexes, including hash indexes, B-tree indexes, non-clustered and clustered indexes
• Transaction handling
• Using SQL in applications, e.g. Java-applications
• Other basic concepts related to relational databases and SQL, such as triggers, views etc.

For data analytics the following topics will be covered:
• OLAP and data warehousing

Eksamensform og -beskrivelse:X: Eksperimentel eksamensform., (7-scale, external exam)

There will be four homework assignments. Each will be graded. There will be a final written exam.
The final grade is computed 15% for each homework + 40% final exam.

The duration of the written examination on premises is 4 hours with following restrictions:

Restrictions:
1. Physical copies of the book and other printed materials are permitted.
2. Ebooks on laptops, ipads, and other e book readers are permitted.
3. Cell phones are *not* permitted.
4. It will *not* be permitted that you access any other other information from the internet, including newsgroups, social media, email, facebook twitter, etc. or elsewhere that is not in book form.

The reexam form will depend of the number registered for re-exam
