How to use an erd template.
- 01Identify core entities
List the main objects your clinic manages—patients, practitioners, services, products, appointments, and sales.
- 02Define relationships
Map how entities connect: a patient can schedule many appointments, each treatment uses certain products, etc.
- 03Add attributes
Specify fields for each entity, like patient name, phone, email, appointment date, and inventory quantity.
- 04Normalize the schema
Refine the structure to eliminate redundancy and ensure data integrity (e.g., separate lookup tables).
- 05Customize and share
Use our editor to tweak the diagram, then export SQL or share a live link with your team.
Questions about erd templates
What tables are essential for a dermatology clinic database?
Typically you’ll need tables for patients, practitioners, services, appointments, product inventory, sales, and billing. Many clinics also track treatment sessions and before/after photos.
How do I model inventory for aesthetic products?
Create a product table with fields like SKU, name, category, price, and stock quantity. Link it to sales and appointment usage with junction tables to track consumption per treatment.
Can I generate SQL from these ER diagrams?
Yes! Once you’ve designed your schema in our editor, you can export the DDL (CREATE TABLE statements) for MySQL, PostgreSQL, or SQL Server and run it directly in your database.
Is this ERD tool free to use?
Absolutely. Our diagram maker is free, requires no login, and you can start designing instantly. Exports and sharing are included at no cost.
What’s the difference between an ERD and a database schema?
An ERD is a conceptual diagram showing entities and relationships, while a database schema is the physical implementation—tables, columns, types, and keys. Our tool bridges both: you draw the ERD and get the schema.
