Unit 4 Digital Impacts - Topic 2: Complex digital data exchange problems and solution requirements

In this topic, students will:

• analyse problems and information to determine
  • boundary of scope of given problems
  • constraints and limitations of environments
  • requirements of the solution components
  • necessary coded modularity and features
  • factors and risks that affect data security, including confidentiality, integrity and availability, and privacy
  • existing code within inbuilt libraries
  • prescribed and self-determined criteria to appraise the implementation, e.g. protection, security and interactions
• analyse, evaluate and make refinements to data to ensure completeness, consistency and integrity
• analyse and explain a system’s data process by developing data flow diagrams that link external entities, data sources, processes and data storage
• determine manageable aspects of a problem through a decomposition and analysis of
  • constraints
  • risks
  • available tools and code libraries
  • data storage and output requirements
  • data interface
• determine data sources required to generate data components
• symbolise algorithmic steps as pseudocode
• explain the purpose of code and/or algorithm statements using code comments and annotations
• communicate using
  • digital technologies–specific language
  • language conventions; textual features such as annotations, paragraphs and sentences; and referencing conventions to convey information to particular audiences about digital solutions
  • sketches or diagrams to present information and ideas about the problem and programmed digital solutions
  • the modes of visual, written and spoken communication to present data and information about digital solutions.
