Course number
Databases and SQL
Introductions into Computer Science, Java and C++
To give the student a first introduction to databases, database management systems, SQL and database design.
The course starts with an introduction to SQL and database management systems. It continues with a discussion of entity relationship modeling. Then the relational model as well as mapping rule for turning an entity relationship diagram into a relational schema is discussed. Finally 3NF and BCNF as well as respective design algorithm are discussed. Transactions, concurrency, XML and blockchain databases are the final course issues.
Learning and teaching approaches
There will be lectures and practice exercises on each course day. The course starts march 25 of 2019. The course days are Monday and Thursday. The teaching covers 8 teaching weeks with one week Easter break. The classes last from 9 am to 3 pm. The details will be agreed on at the first meeting. The classes will take place in the U407 in Sjóvinnuhúsið. Attending the classes is very strongly encouraged. The assignments will be issued at the beginning of the course. A mini-project will be discussed and implemented in class. Late hand ins will only be accepted in case of sickness as certified by a medical doctor.
Learning outcomes
The successful student will be able to: • Create an external database model with the entity relationship model. • Create a conceptual database model suited for an external database model. • Install the SQL database management system and create a database. • Define and execute low to medium level complexity SQL queries. • Define and explain the relational database model including its most important data constraints. • Explain the potential causes and consequences of redundancy implied anomalies to maintaining data. • Define 3NF, BCNF and execute the synthesis algorithm for achieving 3NF. • Explain why transactions are used and what ACID-transaction are. Explain what conflict-serializability and deadlock means and why these concepts are important for transaction processing.
Assessment method
Oral exam bases on short report produced by students in groups during the course. The mini project report counts 50% and the exam 50% in the student’s grade. Failing students may be reexamined by amendment to their report and a repeat exam.
