A schematic of the entire database that describes the relationship between the database objects is called a Database Diagram. Database diagrams are graphical representations of the structure of a database and the relationships between the database objects. They are used to visually represent the structure of a database, including tables, columns, and relationships among them.
Database diagrams are essential for building and maintaining databases. They provide an overview of the database structure and help maintain consistency and accuracy in the structure of the database. They also help in understanding the structure of the database and the relationships between the database objects.
Database diagrams can be used to create different types of schemas. Schema diagrams are used to show the different types of relationships between database objects. For example, a schema diagram might show the relationship between two tables, or between a table and a view. Schema diagrams also help in understanding complex relationships between multiple objects.
Creating database diagrams is an important part of the database design process. It is important to ensure that the diagrams are accurate and precise in order to avoid potential errors and to ensure that the database is working properly. tools such as PhpStorm and DrawSQL are available to help create and maintain database diagrams.
In conclusion, a schematic of the entire database that describes the relationships in a database is called a Database Diagram. Database diagrams are essential for understanding and maintaining the structure of a database, and are vital for successful database design.
