Data modeller

Description

A data modeller is responsible for creating a graphical model or a data model of how data will be stored. A data model is a way of structuring and organising the data that will be stored in a database. The model will also show how each piece of data should relate to every other piece of data.

The data model will also show a number of rules regarding the data. These rules will place constraints on the data to ensure there is integrity in the way the data is stored and displayed to users. The model ensures that each piece of data has an identity, it also establishes whether each piece of data is either a unique identity or if there can be multiple instances of data. For example a database that holds information about clients needs to ensure that each client is unique, so therefore the data model will show that the client is a unique piece of data.

The data modeller will work closely with key stakeholders from the business to determine the data requirements. This is generally completed as part of the database or information system design project.

A data modeller exhibits capabilities in line with the Skills Framework for the Information Age (SFIA)[1] and the Queensland Public Service Workforce Capability Success Profile.[2]

Within the SFIA profile, the data modeller has level 3 and 4 capabilities, i.e. applies and enables the skills outlined below.

Queensland Government roles align with the Queensland Public Service Workforce Capability Success Profile.

The success profile is a sector wide, one-government approach to the leadership behaviours expected of all public sector employees to support high performing workplaces.  The profile describes three performance dimensions (vision, results and accountability) and 13 leadership competencies required against four role types: 

  • Individual contributor (manages self)
  • Team leader (manages individuals)
  • Program manager (manages multiple teams/projects)
  • Executive (manages program managers)

When developing a Role Description, identify the role type and then focus on the most important attributes and create a balance between SFIA skills and leadership skills. 

Entry points

To have a career as a data modeller a bachelor level degree in areas such as information technology, information systems or business is required.

 

  1. The Skills Framework for the Information Age (SFIA) provides a common language that integrates with an organisation’s way of working, to improve capability and resource planning, resource deployment and performance management.  This role profile quotes extensively from the SFIA, under licence from the SFIA Foundation.  Information about the SFIA can be found at http://www.sfia-online.org/en
  2. The Queensland Public Service Workforce Capability Success Profile plays a key role in translating the government’s ‘talent management requirements’ into clear behavioural terms, while at the same time delivering organisational change and growth.  The success profile is being utilised to align sector-wide talent management strategies, including workforce planning, talent acquisition, leadership development, capability development, performance management, career management and succession planning.
