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. Determine context of the business need or problem | 1.1 Develop the database objectives and identify the expected outcomes to be achieved 1.2 Document the database problem |
2. Gather information | 2.1 Analyse the database in order to identify the business rules, entities and relationships 2.2 Identify the existing and proposed business models 2.3 Identify any possible Big Data applications |
3. Determine the database functionality | 3.1 Document the existing database and the environment 3.2 Confirm database functionality with the client |
4. Identify scalability and functionality | 4.1 Identify the reserve, and long-term capacity, of the database 4.2 Identify the implications for the system’s architecture, data models, data structures, hardware and software 4.3 Identify the requirements for scalability 4.4 Compare the functionality and scalability features of the database 4.5 Determine and document any gap between the features |
5. Prepare the database functionality and scalability report | 5.1 Document the functionality and scalability of the database 5.2 Submit the report to the client for review |
Evidence of the ability to:
document a clear statement of business expectations and needs, including critical business requirements
examine the scalability, and functionality, of a database in light of future growth
determine database functionality and scalability system requirements
present the findings in a report to the client.
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 the architecture of the network in which the database resides
identify and explain, the code of ethics relevant to the computing industry in Australia
identify the common system hardware related to the client, server and database architecture
explain the concept of data modelling
outline the functions and features of databases
define "Big Data", and explain its implication for database design and functionality.
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 database field of work, and include access to:
equipment and materials
industry software packages
a database management system (DBMS)
a sample database and data.
Assessors must satisfy NVR/AQTF assessor requirements.
