The Module Description is a strict subset of this Syllabus Page.
The aims of this module are to:
- Introduce the fundamentals of database theory
- Introduce the core of the SQL query language
- Enable students to design a database
On successful completion of this module, the student should be able to:
- Use SQL to create, modify and query databases
- Analyse a real-world scenario and perform a conceptual database design for it
- Take a conceptual data design model and translate it into the relational model
- Use an existing database system
2 hrs lectures/tutorials per week (plus 22 hours of assisted labs)
- Tables and SQL: using the existing relational database implementation, simple select queries, nested queries, aggregate functions, grouping, table creation and modification, etc.
- Conceptual database design: entities and relationships, generalisation hierarchies, keys and weak entities, ER diagrams.
- Logical database design and relational theory: translating ER diagrams into tables, relational algebra, functional dependencies, normalisation, de-normalisation.
- Discrete-mathematical underpinning of database relations, relationships and relational algebra.
