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

Perfect Use Cases

E-commerce Platform Design

Use this template as the foundation for any online store database. The customer-order-product structure covers the core of most retail applications.

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.

How to Customize

1

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.

2

Define Relationships

Connect entities by selecting source and target, setting cardinality (one-to-many, zero-or-more), and choosing identifying or non-identifying type.

3

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.
