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)).

Information about the course of study
This course is mandatory for students who are enrolled on on the Master of Science in IT, study programme Software Development, Design track and please notice that the course is only open for students enrolled in Master of Science in IT. 
Læringsmål:After the course the students should be able to:

* 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:Please note, that due to technical challenges, changes may occur before the start of the semester (week 35) – this applies to all sections of the course description.

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 
Læringsaktiviteter:12 forelæsninger og 12 øvelsesgange

There will be a TA session, where the students can work together/get help from the TA.
