10 Credits or 5 ECTS Credits

Semester 1

Overall aims and purpose

To provide students with an introductory level of understanding of database systems: concept of a database, database management systems, ER and EER modelling and the relational model, database modelling, normalization, and SQL.

Course content

Concept of a Database What is a database; their uses and benefits; what came before; what is a DBMS. What information can be stored. Issues over storing user data in a database. Ethics of storage, dissemination and use. Principles: Accessible, Confidential, Completeness.

Database Modeling Database Design Concepts, Entity Relationship Modeling, UML diagrams and Extended Entity Relationship Modeling.

Relational Databases Basic concepts of relational model; relational algebra (e.g. select, project, union, intersection, Cartesian, theta join).

Transforming Transforming the E/R model into a relational database.

Normalisation First, second, third and Boyce-Codd normal forms.

SQL Creating, updating and querying tables using SQL; linking of SQL to relational algebra.

Learning outcomes mapped to assessment criteria







Understand and describe the major characteristics of a relational database.

Can explain in outline the concept of a database. Can describe some of the problems assocaited with the traditional file based approach. Can describe the structure of a DBMS and identify the principal components. Can describe in outline the ANSI-SPARC three layer model. Can offer a sophisticated explanation of the ANSI-SPARC three layer model.

Use SQL to create, query and update a database.

Can understand and write a range of basic SQL statements(both DDL and DML) Can understand and write queries involving multiple tables (JOINs and Nested Queries0. Can develop and interrogate a non-trivial database (e.g. containing five or more tables). Can define appropriate key structures, referential actions and indexes.

Understand relational model and have an awareness of relational algebra.

Be able to recognise basic relational algebra expressions involving select and projection A basic understanding of Cartesian and join operators. Be able to write and understand simple relational algebra operations.

Use normalisation techniques.

Can transform a simple ER model that does not contain too many relationships. Can transform an ER/EER model involving many relationships and subclasses. Can transform a large complex ER/EER model involving many different types of relationships and subclasses.

Understand and use E/R diagrams. Understand and use EER diagrams.

.Can describe 1NF, 2NF and 3NF. Can explain why these forms are important in the process of database design Can examine a given set of relations and if necessary convert to 3NF. Can describe BCNF. Can examine a given set of relations and if necessary convert to BCNF.
