Hi Faiza
Thanks for posting in the Community!
In Lucidchart you can create Entity Relationship diagrams (ERDs) based on crow's foot notation with customized text styling and relationships between fields. It is possible to generate your ERD either manually or automatically using our SQL import feature.
You can find all information about this feature here: Create an Entity Relationship Diagram in Lucidchart
If you're interested in deepening your knowledge of the ERD symbols and notation please give the following article a quick read: Entity-Relationship Diagram Symbols and Notation
Lastly I am linking below a few templates that are free to use:
ERD (crow's foot): this hockey ERD template can help you understand how entities relate to each other within a system using crow's foot design or debug relational databases and share ideas and collaborate with colleagues.
Database ER diagram (crow's foot): this database ER diagram template can help you illustrate how entities relate to each other within a system using crow's foot design or debug relational databases and easily share and collaborate with others.
Let us know if you have any questions!
