Expert Solution

Step 1

Data Modeling:

The process of creating a framework that outlines the data relationships within a database or data warehouse is known as data modeling. To define associations and limitations between datasets, a visual schema must be created. It provides a conceptual representation of the data and shows how different datasets interact inside a system. Three main viewpoints on data models are as follows:

Conceptual Model: It emphasizes identifying the entities within a system, their properties, and the interactions between them. It is a visual depiction of database ideas.

Logical Model: It gives a technical breakdown of data structures and rules, describes the structure of the entities, and adds more context to their interactions.

Physical Model: It is a framework or schema that describes how a database will be used to build the model. The tables, columns, data types, etc. are represented by it.
