How is data modelling?
Data modeling is a process of creating a conceptual representation of data objects and their relationships to one another.
The process of data modeling typically involves several steps, including requirements gathering, conceptual design, logical design, physical design, and implementation.Jun 6, 2023.

What is the difference between a data model and a data structure 20 points?
The data structures include the data objects, the associations between data objects, and the rules which govern operations on the objects.
As the name implies, the data model focuses on what data is required and how it should be organized rather than what operations will be performed on the data..
