This unit delivers the fundamental principles needed to effectively design and use databases. Databases are the tool used to create, store, organise, and disseminate data. It seeks to unpack the notion of data, and introduce contemporary tools and techniques for storing, retrieving, exploiting, and visualising data. Emphasis is given to understanding data modelling and design approaches, and the emerging opportunities afforded by big data, social media, data analytics, and unstructured data. The unit focuses on commercial and open-source database management tools.
