What are data modelling tools?

Data modeling tools are software applications that assist in creating, visualizing, and managing data models. These tools provide a graphical interface for designing databases, defining entities and relationships, and generating database schema scripts. They play a crucial role in the database development process by helping data architects, database administrators, and developers design and maintain efficient and well-structured databases.
