Object Orientated Programming

Define and decompose real-world problems precisely, taking into account functional and non-functional requirements and including interviewing stakeholders to identify needs (VCDTCD050)

• • developing a preliminary specification for an opportunity or a need that typically contains a problem statement, a set of solution needs expressed as functional and non-functional requirements, any assumptions or constraints to be considered and the scope or boundaries of the solution

  • investigating different types of functional requirements for solutions, for example increasing the speed of processing, calculating new results, improving the quality of reports

  • investigating different types of non-functional requirements for solutions, for example considering how the requirements of reliability, user-friendliness, portability and robustness could affect the way people use solutions

Develop modular programs, applying selected algorithms and data structures including using an object-oriented programming language (VCDTCD053)

• • coding separate modules that perform discrete functions but collectively meet the needs of the solution

  • defining classes that represent the attributes and behaviour of objects in the real world or in a game

  • considering different algorithms and selecting the most appropriate based on the type of problem, for example branching algorithms suit optimisation problems and simple recursive algorithms solve the base cases directly

  • selecting different types of data structures such as an array, record and object to model structured data

• Design the user experience of a digital system, evaluating alternative designs against criteria including functionality, accessibility, usability and aesthetics (VCDTCD051)

  • evaluating aspects of the total user experience, that is, all aspects of the system as perceived by the users, for example, a user’s initial experience of setting up and using a system, or a user’s emotional or cultural response to using a digital system

  • designing documentation, branding and marketing for a digital solution, for example a product demonstration screencast or ‘getting started’ user guide

  • applying the principles and elements of design to a client’s requirements and evaluating the success of a solution through an iterative feedback process, for example using customer feedback to refine a user interface to provide access to important features more effectively
