5.1 Arrange for users to have ongoing training in the data warehouse

5.2 Validate the test results

5.3 Obtain sign-off for the data warehouse

Evidence of the ability to:

prepare the specifications for a data warehouse, from a range of organisational information

design a data warehouse system that reflects the current, and future, business specifications, and also the business’s knowledge management strategy

test the data warehouse system

implement the data warehouse design.

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 functions and features of:

data warehousing and data mining

dimension tables and fact tables

various steps and processes, including transformer steps, program steps, structured query language (SQL) steps, and user-defined program steps

subject areas, warehouse sources and warehouse targets

warehouse agents and agent sites

outline the business operating systems related to the data sources

describe the decision support systems related to the knowledge management strategies

define the parameters for a security plan

outline the system’s configuration parameters

describe the key features of "Big Data" including:

data access speeds and processing

the information handled by large corporations

distribution, via the cloud, across the database servers.

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

the business requirements

computers configurable as information servers

the enterprise’s knowledge management strategy

internet connectivity tools

the local area network (LAN), with a relational database management system (DBMS)

proxy server software

specialised internet security software.

Assessors must satisfy NVR/AQTF assessor requirements.
