Data Modelling

Data modeling is the process of creating a visual representation of the data that is used by an organization or business. This representation is used to understand the relationships between different pieces of data, and to design systems and applications that can use the data effectively. Data modeling is a critical skill for data analysts, database designers, and anyone else who works with data.
