Prüfungstermine:

Als Prüfungstermine bieten wir den 19.07. sowie die Woche vom 13.-16.08. an. Einige wenige Ausweichtermine für diejenigen, bei denen es im August (oder Juli) gar nicht geht, wird es in der Woche vom 3.-7.9. geben. Allerdings werden diese Prüfungstermine alle am späten Nachmittag (ab frühestens 16 Uhr) liegen und die Anzahl ist stark begrenzt.

Meldungen für die Prüfungen bitte bei Frau Dalkiran im Sekretariat des IFIS in Raum 236.

In contrast to Relational Databases 1, this lecture will focus on how to implement a relational database. All major challenges are discussed and different solutions are presented.

The focus will be on

  •       basic architecture of relational databases
  •       index structures
  •       query processing
  •       query optimization
  •       transaction management
  •       data security
  •       non-standard Implementations

 

What you will you learn? Which questions are answered?

  • How to build a relational DB?
  • How does query processing work?
  • Why do index structures speed up queries? Which index structures are there? What are their advantages / disadvantages? Which one to use?
  • Why did we burden students with relational algebra in RDB1 when there is SQL?
  • How does relational algebra help in query optimization?
  • Which optimization paradigms are there? How do they work?
  • Why do database administrators get paid that well?
  • What is transaction management for? What has to be done to implement it? What alternatives are there?
  • How can you ensure that data is not lost?
  • How to harded you DB againt power outages, fires, or earthquakes?
  • How else can I implement a relational database?
  • ... and many more!

Which pre-requisites are there?

  • No special requirements. However, successful participation in Relational Databases 1 is highly recommended.
  • It is a Masters course. Bachelor students may attend the lecture according to their examination regulations.
