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.
