Seeing the whole data ecosystem
This topic provides a conceptual foundation. The focus is on purpose, people and relationships rather than specific technologies.

Learning outcomes
By the end of this topic, students should be able to:
- Explain the purpose of data engineering in organisational settings.
- Differentiate raw data from useful information.
- Identify the principal components and professional roles in a data ecosystem.
- Trace data through a six-stage organisational journey.
- Analyse a familiar digital service as a data ecosystem.
- Evaluate basic data quality, privacy and responsibility concerns.
Meaning and purpose
Learn what data engineering is and why raw data needs to be organised before it becomes useful.
The ecosystem
See how data producers, organisational processes, responsible people and data users are connected.
People and roles
Understand how data engineers collaborate with analysts, scientists, administrators and business users.
Everyday examples
Trace data through familiar services such as course registration, online banking and food delivery.
Scope for Topic 5: Focus on the big picture. Technical platforms, detailed architectures and implementation methods will be introduced in later topics.
