How to Add References to ER Diagrams in Vertabelo
Adding references to your data model is essential to maintaining clarity.
A Quick and Easy Introduction to Entity Relationships In data modeling, defining relationships between tables/entities entails using a certain notation to indicate the cardinality between them. This applies to both logical and physical data models.
Cardinality refers to how many instances of one entity are related to the other entity. For example, a database that keeps track of orders on an e-commerce website likely has customer and order entities.

Have you ever wondered how data modeling works?
Data modeling is the process of creating a data model. A data model can be thought of as a blueprint that describes the structure and internal relationships in a database. It is meant to demonstrate how objects within the database interact with each other to fulfill the prescribed business logic.
Since relational databases are composed of tables, a data model is a diagram that illustrates the relationship between these tables.
