Apply intermediate object-oriented language skills


Application

This unit describes the skills and knowledge required to undertake intermediate level programming tasks using an object-oriented programming language.

It applies to programmers in a variety of fields who are required to produce programs in object-oriented languages.

No licensing, legislative or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

ELEMENT

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Build applications using the provided language utilities

1.1 Review the program requirements

1.2 Divide multiple source-code files into logical units and packages

1.3 Use at least two of the utilities of the target language, allowing for the internal storage of collections of data

1.4 Use the utilities of the target language, providing internal data-sorting and searching facilities

1.5 Employ integrated-development environment facilities, to make files to automate program building

1.6 Follow the guidelines for developing maintainable code, adhering to coding standards

1.7 Use the facilities in the language for persisting objects to binary files

1.8 Use the operator and function or method overloading facilities available in the language, at an introductory level

1.9 Use exception-handling techniques to ensure program stability

1.10 Use of a class that is based on multiple inheritances

2. Write programs that interact with a database

2.1 Design and implement programs that connect to a database

2.2 Design and implement programs that use the language facilities to extract, update, and delete data stored in a database

2.3 Design and implement programs that use the language facilities to manipulate database structure (query, create and delete)

2.4 Write programs that deliver transactional integrity

3. Write the graphical user interface

3.1 Employ the graphical user interface (GUI) framework, or text windowing interface, appropriate to the chosen language

3.2 Use standard GUI components

3.3 Use the facilities within the language for GUI objects to respond to user and program-generated events

4. Debug the application

4.1 Use stand-alone debugging tools, or tools provided by the integrated development environment, to examine variables, and trace the running code

4.2 Use the debugger to detect logical and coding errors

4.3 Use the tracing of code and examination of variable contents during execution, to detect and correct errors

5. Test the application

5.1 Design and document limited tests of code

5.2 Undertake limited testing of the produced code to ensure that it complies with the program specification

5.3 Capture and document the test results

6. Create and maintain documentation

6.1 Read and interpret the supplied design document, to create the code

6.2 Create and maintain program documentation

Evidence of Performance

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.


Evidence of Knowledge

To complete the unit requirements safely and effectively, the individual must:

explain data structures

explain small-size and medium-size application development

define object-oriented programming concepts

define object-oriented programming language

explain the process and techniques related to the use of a graphical user interface (GUI), to interact with an operator

outline the techniques to document applications.


Assessment Conditions

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the programming and software development industry, and include access to:

the requirements document or object-oriented design structures

programming languages that support object-oriented development

the database management system (DBMS)

the appropriate learning and assessment support

Assessors must satisfy NVR/AQTF assessor requirements.


Foundation Skills

This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
