EER(Enhanced entity-relationship) diagrams are basically a more expansive version of ER diagrams. EER models are helpful tools for designing databases with high level models, with their enhanced features. you can plan databases more thoroughly by delving into the properties & constraints with greater precision.

It is to establish structured metadata commonality for the master data entities between the set of logical ER models.

After creating database script, import data into MySQL workbench using new schema. To create EER diagram, we need to follow these steps. select Database -Reverse Engineer (ctrl+R)- Hostname password- select schema- select objects to Reverse engineer- Execute. It will show EER diagram with our tables and their relationships automatically.
