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.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Prepare the system for conversion | 1.1 Obtain the data stores that are subject to conversion 1.2 Protect and confirm backup solutions 1.3 Trial conversion work in an isolated environment, secure from the production system 1.4 Map and document, the required data fields from the old system to the new or upgraded system 1.5 Determine field validation requirements from conversion plans, including data field legal ranges 1.6 Determine the actions to be taken with the fields or records that are rejected by the conversion plan 1.7 Consult stakeholders on the creation of a conversion plan 1.8 Design the data conversion program modules from the conversion specifications 1.9 Code and test data conversion program modules, according to conversion specifications 1.10 Confirm data conversion and test the converted production data |
2. Perform data conversion | 2.1 Estimate and plan for conversion time 2.2 Prepare the production system for data conversion and take off-line 2.3 Undertake action to protect production data 2.4 Take action to ensure minimal disruption to client business requirements during the conversion process 2.5 Document the data rejected by conversion routines, and the reason for rejection 2.6 Execute the conversion program modules 2.7 Document the results of the conversion process, and report to the appropriate person |
Evidence of the ability to:
define the inherent data requirements of both old and upgraded, or new systems
remodel data to achieve successful conversion
back up data prior to conversion
effectively code conversion programs.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
explain hardware and software products, including their general features and their capabilities
explain data conversion tools and data modelling methodologies
outline the conversion from legacy systems
outline industry-accepted database management system (DBMS) modelling.
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:
analysis of the source data
business quality assurance rules associated with data
data mappings
logic to convert the data
plan of the conversion routines
software development environment
technical requirements
data conversion plan
appropriate learning and assessment support.
Assessors must satisfy NVR/AQTF assessor requirements.
