Data Architect Certification - Relationships in data

[sai_katare]

Hi. I was going through the certification 'Knowledge and Abilities' document and found this point:

Design Data Models (28% of the exam)
• Given a data set, determine the relationships among data and how the relationships will affect the Qlik Sense data model (e.g., performance, accuracy, scalability)

can some please explain this point to me. I am confused about this? 

Thanks.

@sai_katare  your data model development can create performance problems if it is not correctly done.
In this post you will have an idea: Data Model Optimization.
I would also check this section of our help page Best practices for data modeling.
Circular reference and synthetic keys are also good topics to search for.
