1. Develop client-server application | 1.1 Build and test object-oriented applications 1.2 Make use of the features of the language that enable inter-process communication through at least one mechanism 1.3 Make use of the features of the language that enable remote procedure calls (RPC) using a class that is based on multiple inheritances 1.4 Build programs using classes that are based on nested classes |
2. Develop graphical user interface (GUI) | 2.1 Code to implement drag and drop 2.2 Develop GUI help files 2.3 Code using 2-D graphics |
3. Build applications | 3.1 Code within an existing architectural framework 3.2 Ensure code follows standards for object-oriented language 3.3 Develop an application that includes data transfer between client and server 3.4 Review the concept of design patterns used by the architectural framework |
4. Debug code | 4.1 Use stand-alone debugging tools or tools provided by integrated development environment to examine running code 4.2 Detect logical and coding errors using debugger 4.3 Detect and correct errors by tracing code and examining variable content |
5. Test application | 5.1 Design and document tests to be undertaken 5.2 Undertake limited testing of produced code to ensure it complies with program specification 5.3 Document test results |
6. Document system | 6.1 Demonstrate adherence to guidelines for developing maintainable code and company or institutional coding standards 6.2 Create code using supplied design documents 6.3 Create and maintain program documentation 6.4 Ensure that user documentation in the form of online help is built into applications |

Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.
Overview of assessment | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Evidence of the ability to: design an application to meet user requirements using object-oriented techniques build an application program using a range of tools for a given problem test application to ensure that it meets client requirements document the application. |
Context of and specific resources for assessment | Assessment must ensure access to: database management system (DBMS) networked computers software-development environment technical requirements appropriate learning and assessment support when required modified equipment for people with special needs. |
Method of assessment | A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit: evaluation of completed application review of: application documentation testing documentation verbal or written questioning to determine knowledge of: object-oriented techniques and terms DBMS access software testing. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate. Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed. Indigenous people and other people from a non-English speaking background may need additional support. In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Mechanism may include: | pipes sockets. |
Architectural framework may include: | J2EE .NET. |
Integrated development environment may include: | Code Warrior Eclipse JBuilder J-Edit Visual C++ Visual Studio suite WebSphere. |
Coding standards may include: | GNU Java. |
Sectors
