What This Template Offers
A complete e-commerce database ERD with 7 entities, primary/foreign keys, and labeled relationships - ready to adapt for your own schema.
- 7 pre-built entities: CUSTOMER, ADDRESS, CATEGORY, PRODUCT, ORDER, ORDER_ITEM, and PAYMENT
- Primary keys (PK), foreign keys (FK), and unique keys (UK) clearly labeled on every attribute
- Identifying and non-identifying relationships with standard cardinality notation
- Left-to-right layout with zoom and pan support for navigating large schemas
- Fully editable entities, attributes, and relationships in a visual config panel
Use cases
Perfect Use Cases
Database Documentation
Share a clear visual of your existing schema with developers, stakeholders, or clients. ERDs communicate structure far faster than raw SQL scripts.
Technical Interviews and Assignments
Demonstrate your database design skills with a polished ERD. Adapt this template to any domain such as healthcare, logistics, or finance.
System Architecture Planning
Plan new features by extending this schema with additional entities. Catch relationship gaps before writing a single line of code.
Customize
How to Customize
Edit Entities and Attributes
Rename entities, add or remove attributes, and assign key types (PK, FK, UK) using the visual config panel - no SQL required.
Define Relationships
Connect entities by selecting source and target, setting cardinality (one-to-many, zero-or-more), and choosing identifying or non-identifying type.
Adjust Layout and Export
Switch direction (top-bottom or left-right), resize the canvas, then download as PNG or SVG to use in docs, slides, or presentations.
Key Benefits
- Realistic e-commerce schema you can adapt immediately - not a toy example
- Cardinality notation follows standard ERD conventions used by developers and DBAs
- No diagramming software to install - works entirely in your browser

Pro Tips
- Add a REVIEW or COUPON entity to extend the e-commerce schema for your specific use case
