Data modeling is the process of creating a visual representation of the data in a database, which helps to organize and structure the information in a way that can be easily understood and accessed. This includes defining data entities, their attributes, and the relationships between them. Data modeling is essential for designing databases that are efficient, scalable, and able to meet the needs of the users. It is commonly used in fields such as relational database management, data warehousing, and business intelligence to improve data management and analytics.
