Evidence Required
List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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 following is essential: Assessment must confirm the ability to design a well-structured database that represents the client's business reality and provides the user with a productive business tool. To demonstrate competency in this unit the learner will require access to: Current industry-accepted database software, network or other system for remote or multi-user access Business requirements |
Context of and specific resources for assessment | The breadth, depth and complexity covering planning and initiation of alternative approaches to skills or knowledge applications across a broad range of technical and/or management requirements, evaluation and coordination would be characteristic. Assessment must ensure: self-directed application of knowledge and skills, with substantial depth in some areas where judgement is required in planning and selecting appropriate equipment, services and techniques for self and others. Applications involve participation in development of strategic initiatives as well as personal responsibility and autonomy in performing complex technical operations or organising others. It may include participation in teams including teams concerned with planning and evaluation functions. Group or team coordination may also be involved. |
Method of assessment | The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1. Competency in this unit should to be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency. Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process. The interdependence of units for assessment purposes may vary with the particular project or scenario. |
Guidance information for assessment | Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example: ICAB4170B Build a database ICAA5153B Model data objects ICAA5154B Model data processes An individual demonstrating this competency would be able to: Demonstrate understanding of a broad knowledge base incorporating theoretical concepts, with substantial depth in some areas Analyse and plan approaches to technical problems or management requirements Transfer and apply theoretical concepts and/or technical or creative skills to a range of situations Evaluate information, using it to forecast for planning or research purposes Take responsibility for own outputs in relation to broad quantity and quality parameters Take some responsibility for the achievement of group outcomes Maintain knowledge of industry products and services |

Assessment Tasks
Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.
Required skills |
Techniques to elicit information from users, particularly during the design and prototype phases Analysis skills to determine data objects required, data structures and business requirements Data modelling skills Business analysis skills SQL programming skills Communicating with clients |
Required knowledge |
Function and features of databases Logical design concepts, particularly in relation to designing data structures, queries screens and reports Data modelling in relation to developing the conceptual data model Object model design concepts, particularly in relation to designing data structures, queries, screens and reports Data analysis, particularly in determining data types and data structures and query and report design DBMS fundamentals, particularly during the design phase Function and features of data types and data structures Data redundancy Encryption and authentication as they apply to database security features Scalability of databases |
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. | |
Client may include but is not limited to: | internal departments external organisations individual people employees |
Database may include but is not limited to: | relational databases object-relational databases proprietary databases commercial off the shelf (COTS) database packages |
Technical requirements may be in reference to: | business system platform database network people in the organisation |
Documentation may follow: | ISO/IEC/AS standards audit trails naming standards version control project management templates report writing principles |
Database management system may include: | distributed or centralised on-line partitioned geographically or thematically distributed |
Security plan may include: | privacy authentication authorisation and integrity usually relates directly to the security objectives of the organisation |
Requirements may be in reference to: | business system platform database network people in the organisation |
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
