Two benefits of Data modelling?

1. Improved understanding of data: Data modelling helps to create a visual representation of the data structure, relationships, and constraints within a database. This allows for a better understanding of the data and how it is organized, making it easier to analyze and manipulate.

2. Improved communication and collaboration: Data modelling provides a common language and framework for discussing and documenting data requirements and structures. This can help facilitate communication and collaboration between different stakeholders, such as business users, data analysts, and database developers, leading to more effective decision-making and problem-solving.
