Build a data warehouse

Assessment tool

Version 1.0
Issue Date: April 2024


This unit describes the skills and knowledge required to design, develop and implement a data warehouse within an organisation.

It applies to individuals managing a knowledge management team, or works in a senior role in such a team with line management responsibility.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


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.

ELEMENT

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1. Confirm the database design

1.1 Review the database design document, including the data structures, queries, reports and user interface

1.2 Identify any possible "Big Data" applications

2. Identify the required data and sources

2.1 Identify the required data, with reference to the enterprise’s knowledge management strategy

2.2 Identify subject areas, with reference to the business processes and the required data

2.3 Explore operational data, define the warehouse sources and record the outcomes

2.4 Develop the warehouse source specifications, with reference to the existing data tables and files

3. Determine warehouse operational steps and processes

3.1 Develop the warehouse targets, with reference to the business processes and the required data

3.2 Identify the warehouse agents, according to the system’s configuration

3.3 Identify and develop, warehouse steps and processes

4. Design and develop the warehouse features

4.2 Develop and implement the warehouse security strategy, according to the enterprise’s security plan

4.3 Identify dimension tables and fact tables, with reference to the required data

4.5 Develop a warehouse information catalogue, with reference to the enterprise’s knowledge management strategy

5. Test and implement the data warehouse

5.1 Test the data warehouse against the business requirements, to ensure that iterations meet the business objectives

5.2 Recommend changes to business processes, to ensure compatibility with the data warehouse and the knowledge management strategy

5.3 Implement the data warehouse

5.4 Establish an ongoing maintenance schedule in order to keep the system efficient

5.5 Benchmark and document, the performance level of the data warehouse

6. Finalise work processes

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

6.2 Validate the results

6.3 Obtain sign-off for the data warehouse

Evidence of the ability to:

review and document the database’s design, and security, for the current and future business requirements

identify and document, the specifications for the storage of different types and sources of data

develop a cost benefit analysis for a data warehouse

design, develop, test, and implement a data warehouse that reflects the business’s knowledge management strategy

document the operation of the data warehouse.

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 business operating systems related to the data sources

outline database management system (DBMS) fundamentals, in order to facilitate the extraction of data

define "Big Data" and summarise its use and management, in the corporate sector

identify and apply, the decision-support systems related to knowledge management strategies

explain encryption and authentication as they apply to database security features

outline the functions and features of dimension tables and fact tables

explain the installation and use of proprietary software

explain the logical database model knowledge needed to facilitate data extraction

describe the relationship between databases and data warehouses

define the levels of technical documentation required for newly developed data management systems.

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

data in a DBMS

a data-warehousing tool.

Assessors must satisfy NVR/AQTF assessor requirements.

Submission Requirements

(add new lines for each of the assessment tasks)

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.
