Content

The course introduces database systems with a focus on the relational database model. The course begins with conceptual information modelling based upon ER diagrams. The information model is then refined into a collection of normalised tables that remove duplicated and redundant information. Relational algebra is taught in order to show how information can be extracted and modified in a relational database. Subsequently, the Structured Query Language (SQL) is shown as an industrial variant for practical database querying and transformation. Finally, fundamental principles for transaction management, and the role of database management and database management systems, are discussed.
