Postgraduate Course: Advanced Databases (Level 11) (INFR11011)

Credit level (Normal year taken)SCQF Level 11 (Year 4 Undergraduate) AvailabilityAvailable to all students
SCQF Credits10 ECTS Credits5
SummaryThis course aims at furthering database systems concepts through adding complexity and a more hands-on approach. In particular, we will focus on supporting multi-dimensional data in a DBMS, query optimisation, query evaluation, transaction processing and concurrency control in both a centralised and a distributed context. In terms of centralised databases, we shall start from single and multi-dimensional indexing methods, move on to join evaluation algorithms, and talk about query opimisation paradigms. We shall then focus on the issues of transaction processing, concurrency control and crash recovery. Finally, we shall revisit the previous issues in a distributed database environment.
Course description This is a rough overview of what will ideally be covered if time permits. If needed, the time spent on each part will be adjusted as the course progresses.

* B-trees, hash-based indexes, R-trees and Grid files.
* Query evaluation: join algorithms (nested-loops join, sort-merge join, hash join, Grace join and hybrid-hash join.)
* Query optimisation: cost-based query optimisation, dynamic programming, randomised exploration, rule-based optimisation.
* Concurrency and recovery: transactions, lock tables, optimistic concurrency control, recovery using the ARIES algorithm.
* Distributed databases: distributed query evaluation, distributed transaction processing.

Entry Requirements (not applicable to Visiting Students)
Pre-requisites It is RECOMMENDED that students have passed Database Systems (INFR09011) OR Database Systems (INFR10055)
Prohibited Combinations Other requirements This course is open to all Informatics students including those on joint degrees. For external students where this course is not listed in your DPT, please seek special permission from the course organiser.

A firm grasp of basic mathematics is expected; the course involves extracting cost models from algorithms.

A good level of programming is assumed and will not be covered during lectures. The coursework will involve implementing query processing algorithms in the context of a database system written in Java.
