Entity Relationship Diagram Generator Tool

How to Use the Entity Relationship Diagram Generator

This tool helps you visualize database structures by creating Entity Relationship Diagrams from text descriptions. Simply define your entities, attributes, and relationships in the input field using our simple format, JSON, or SQL DDL statements, then click "Generate ER Diagram" to see your visual diagram.

Input Format Options

Simple Format: Use a simple text-based format where each line represents an entity, attribute, or relationship. For example:

• ENTITY: User - Defines an entity
• ATTRIBUTE: User.id (PK) - Defines a primary key attribute
• ATTRIBUTE: User.name - Defines a regular attribute
• RELATIONSHIP: User HAS_MANY Order - Defines a relationship between entities

JSON Format: Use a structured JSON format to define your database schema more precisely. Example:

• {"entities": [{"name": "User", "attributes": [{"name": "id", "isPK": true}, {"name": "name"}]}]}

SQL Format: Use standard SQL DDL statements that our tool will parse. Example:

• CREATE TABLE User (id INT PRIMARY KEY, name VARCHAR(50));
• CREATE TABLE Order (id INT PRIMARY KEY, user_id INT, FOREIGN KEY (user_id) REFERENCES User(id));

Why ER Diagrams Matter in Database Design

Entity Relationship Diagrams are crucial visual tools that help developers plan database structures before implementation. They provide a clear picture of how different data entities relate to each other, making it easier to discuss, refine, and document database designs.

Use Cases for ER Diagrams

• Planning a new database structure before implementation
• Documenting existing database schemas for team collaboration
• Visualizing relationships between data entities
• Teaching and learning relational database concepts
• Communicating database design decisions to non-technical stakeholders
