Databases are core, if largely invisible, components of modern computing architectures in both commercial and scientific contexts. The management of data has evolved from application-specific management of myriad files to organisation-wide approaches that see data as one of the most important assets of modern organisations and, as such, a key factor in their ability to compete and thrive. At this organisation-wide scale, database management systems (DBMSs) are the crucial piece of software infrastructure needed to achieve the desired results with consistent quality and robust efficiency. A modern DBMS is a thing of wonder and embodies in its internal construction and in its wide usability many advances in algorithms and data structures, programming language theory, conceptual modelling, concurrency theory, and distributed computing. This makes the study of databases a data-centric traversal of many of the most exciting topics in modern computing.
- Be able to discuss and explain the principles of database design.
- Be able to discuss, explain and apply conceptual design methodologies, and, in particular, the Extended Entity Relationship Approach.
- Be able to discuss, explain and apply the relational model, and, in particular the derivation of relational schemas from conceptual designs and the normalisation of those schemas.
- Be able to discuss and explain the basic mechanisms to enforce database security, through an understanding of the threats and countermeasures available in classical database management systems.
- Be able to discuss and explain the requirements and responsibilities arising from the use of classical database management systems in the light of legal frameworks to protect individuals, institutions and property rights.
