Elements and Performance Criteria

1. Build applications using the provided language utilities
   • Review the program requirements
   • Divide multiple source-code files into logical units and packages
   • Use at least two of the utilities of the target language, allowing for the internal storage of collections of data
   • Use the utilities of the target language, providing internal data-sorting and searching facilities
   • Employ integrated-development environment facilities, to make files to automate program building
   • Follow the guidelines for developing maintainable code, adhering to coding standards
   • Use the facilities in the language for persisting objects to binary files
   • Use the operator and function or method overloading facilities available in the language, at an introductory level
   • Use exception-handling techniques to ensure program stability
   • Use of a class that is based on multiple inheritances
2. Write programs that interact with a database
   • Design and implement programs that connect to a database
   • Design and implement programs that use the language facilities to extract, update, and delete data stored in a database
   • Design and implement programs that use the language facilities to manipulate database structure (query, create and delete)
   • Write programs that deliver transactional integrity
3. Write the graphical user interface
   • Employ the graphical user interface (GUI) framework, or text windowing interface, appropriate to the chosen language
   • Use standard GUI components
   • Use the facilities within the language for GUI objects to respond to user and program-generated events
4. Debug the application
   • Use stand-alone debugging tools, or tools provided by the integrated development environment, to examine variables, and trace the running code
   • Use the debugger to detect logical and coding errors
   • Use the tracing of code and examination of variable contents during execution, to detect and correct errors
5. Test the application
   • Design and document limited tests of code
   • Undertake limited testing of the produced code to ensure that it complies with the program specification
   • Capture and document the test results
6. Create and maintain documentation
   • Read and interpret the supplied design document, to create the code
   • Create and maintain program documentation

Performance Evidence

Evidence of the ability to:

design and build application programs from a problem scenario and program specification

use object oriented programming language.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
