The ER diagram is used to express the connection between the data object and the data object. For example, there is a certain connection between the entity of the student and the entity of the grade table. Each student has its own grade table. As the name suggests, an ER diagram depicts the relationship between two or more entities. This could be real-world entities or entity sets of a database. The model helps us build a logical structure of the database or the overall connectivity in software development. This is a kind of relationship. The relationship uses a diamond To represent.
