Unit 3: Informatics

In this unit, students focus on how the characteristics of data and how it is acquired, managed, manipulated and interpreted to meet a range of needs. There are two areas of study: Organisations and data management, and Data analytics: drawing conclusions and they draw on the four concepts that underpin the study.

In Area of Study 1, students use relational database management system software to create a database solution and a graphics tool to represent how data flows on a website when users undertake online transactions.

Area of Study 2 forms part of a School-assessed Task (SAT), and is the first part of a practical project. Students frame a hypothesis, and gather, manipulate and interpret data to draw conclusions that support or refute the hypothesis. Students use software tools to document a project plan and capture, store, prepare and manipulate data.

Unit 4: Informatics

In this unit, students focus on strategies and techniques for manipulating, managing and securing data and information to meet a range of needs. There are two areas of study: Data analytics: presenting the findings, and Information management and they draw on the four concepts that underpin the study.

Area of Study 1 forms the second part of the SAT. Students create a multimodal online solution, that present the conclusions drawn from their hypothesis. This involves using software to create a web-based solution that contains multiple data types. Students also evaluate the quality of the solution and assess how well their project plan helped them monitor the progress of their project.

In Area of Study 2 students focus on how organisations protect the integrity and security of data that they dispose and store. Students do not use software to demonstrate this outcome.

Key Concepts

  1. Approaches to problem solving focuses on ways of creating solutions and thinking about problems, opportunities and needs. A detailed approach to problem solving is explained in the stages and activities of the problem-solving methodology on pages 14 and 16. Overall approaches to problem solving involve computational, design and systems thinking (see glossary on pages 11–13).
  2. Data and information focuses on the nature of data and how data and information can be acquired, structured, represented and interpreted to extract meaning. This process of preparing data and information appropriately is the precursor to creating solutions that meet intended needs.
  3. Digital systems focuses on the functions and technical underpinnings of hardware and software components as well as networks (wireless, wired and mobile) and the internet, including protocols and styles of modern application architecture such as rich client, mobile and internet. This concept also addresses ways in which hardware and software are used to manage and control access to data and its transfer between digital systems. Digital systems form one of the components of an information system along with people, data and processes.
  4. Interactions and impact focuses on the relationships within and between information systems and the effects of these in achieving economic and social goals. Relationships are considered from three perspectives: how people interact with other people when using digital systems for communication and collaboration; how people interact with, or respond to, different types of digital systems; and how information systems interact with other information systems. This concept also considers the impact of these relationships on meeting current and future needs of individuals, organisations and society, including the ownership and privacy of data and information, and personal safety.
