Learn about EER diagrams utilizing the following examples of the diagram that we have collected and provided below!
The EER diagram or enhanced entity-relationship (EER) model in computer science is a high-level or conceptual data model incorporating extensions to the original entity-relationship (ER) model, used in the design of databases.
This diagram was developed to reflect more precisely the properties and constraints that are found in more complex databases. The EER diagrams consist of conceptual models that accurately represent the requirements of complex databases. In an EER model, a subclass entity inherits all attributes and relationships of its superclass entity. This property is called the attribute and relationship inheritance. See all the components in the following examples below.
EER models are helpful tools for designing databases with high-level models and you can plan databases more thoroughly by delving into the properties and constraints with more precision. This diagram includes elements that allow for aggregating, generalizing, and specializing. Generalization and specialization act as opposites of one another. Use this kind of diagram to design or analyze relational databases used in business processes.
When you already understood the concept of this diagram, you can quickly and efficiently sort and group the relationships within the system that you are working on. Some of these examples of the diagram are just simple EER model samples for referential use only. Use these diagrams to sort out relationships within a system and make sure to visit back to get more updates on the other printable educational diagrams!
