Introduction to Data Modeling

As data engineers, one of our main objectives is to drive the business forward. However, sometimes stakeholders know what they want, but they struggle to articulate it and transfer their domain knowledge into a database design. This is where data modeling comes in. It helps us translate business requirements into a visual representation of data and the relationships among data points.

Data can be modeled at various levels of abstraction. The process starts by collecting requirements from business users. These requirements are then translated into a database design consisting of entities and attributes.
