The module begins with a swift recap of the standard database canon: SQL and ER modelling, albeit from a more advanced perspective. This is followed by a discussion of relational algebra and functional dependencies, and their role in verifying and improving the ER model (towards Boyce-Codd normal form). In the second part of the module, the inner workings of a database management system are presented and it is discussed how they impact on query evaluation efficiency. In the final part, transactions and transaction processing will be discussed.


On successful completion of this module, the student should be able to:

1 Use SQL for querying a relational database 2 Design a relational database using extended entity-relationship diagrams 3 Translate extended entity-relationship diagrams into SQL CREATE statements 4 Translate between SQL and relational algebra 5 Analyse a relational database design using functional dependencies and perform transformations towards Boyce-Codd Normal Form 6 Demonstrate an understanding of database implementation principles, and their impact on query evaluation efficiency 7 Structure a series of queries as transactions, and demonstrate an understanding of the impact this has on database behaviour and performance.


Sessional: 1.5 hr examination (80%), continuous assessment (20%).

Supplementary (where allowed): By examination only.

The continuous assessment consists of three class tests.
