About this unit

This unit introduces students to a range of skills, techniques, technologies and fundamental computer science concepts related to managing data within software systems. Students will learn how to organise data, efficiently search and sort information, as well as apply techniques to optimise these operations. Data management is a critical component in most software systems – knowledge and skills gained in this unit can be applied to a range of different solution domains from enterprise systems to smaller desktop and mobile applications.
