Aims

To introduce the fundamentals of database system design and use.

The module introduces the fundamentals of database systems. You will understand and be able to apply the relational data model and be proficient in manipulating database systems. Among the topics covered are: Principles of data models and multi-level architectures; relational data model; user requirements; database conceptual design; SQL standard; database logical and physical design; database procedures; database management.

Teaching Rationale And Relationship

Lectures will be used to introduce the learning material and for demonstrating the key concepts by example. Students are expected to follow-up lectures within a few days by re-reading and annotating lecture notes to aid deep learning.

This is a very practical subject, and it is important that the learning materials are supported by hands-on opportunities provided by practical classes. Students are expected to spend time on coursework outside timetabled practical classes.

Students aiming for 1st class marks are expected to widen their knowledge beyond the content of lecture notes through background reading.

Students should set aside sufficient time to revise for the end of semester exam.

Assessment Rationale And Relationship

In the written examination the questions will assess fundamental knowledge and understanding of theory and application of database design and usage.
The coursework exercise develops knowledge and competence with the various modelling techniques and other skills acquired during the course.

N.B. This module has both “Exam Assessment” and “Other Assessment” (e.g. coursework). If the total mark for either assessment falls below 35%, the maximum mark returned for the module will normally be 35%.
