Schema3D

Schema3D is a free, interactive database visualization tool that transforms your database schema into a beautiful 3D representation. Whether you're a developer, database administrator, or data architect, Schema3D helps you explore tables, views, and foreign key relationships in an intuitive spatial environment.

Import schemas from SQL scripts or Mermaid ER diagrams, organize tables with custom categories, and share visualizations with your team. Schema3D provides everything you need to understand and document complex database structures. Explore the features below to see how Schema3D can enhance your workflow, learn about the technology that powers it, and discover how to get involved with the project.

Features

Interactive 3D Visualization

• 3D Table Rendering: Tables displayed as color-coded 3D boxes by category
• Relationship Lines: Visual connections showing foreign key relationships with PK/FK notation
• Interactive Controls: Rotate, zoom, and pan the camera to explore your schema
• Hover & Selection: Hover effects and click-to-select tables and relationships
• Visual Feedback: Highlighted tables and relationships with smooth animations

Schema Management

• Multiple Sample Schemas: Pre-configured schemas (Retailer Database, Blog Platform, University)
• Dual Format Support: Import schemas via SQL CREATE TABLE statements or Mermaid ER diagrams
• Format Auto-Detection: Automatically detects SQL or Mermaid format when pasting schema text
• Live Syntax Validation: Real-time validation of SQL and Mermaid input with error feedback
• Schema Switching: Easily switch between different database schemas

Layout Algorithms

• Circular Layout: Distributes tables evenly around a circle
• Force-Directed Layout: Physics-based positioning based on relationship strength
• Hierarchical Layout: Organizes tables in layers based on dependencies

Search & Filter

• Real-time Search: Search across table and column names
• Smart Highlighting: Highlights matched tables and related connections
• Focus Mode: Dims non-matched tables for better focus

Category Management

• Dynamic Filtering: Toggle visibility of specific table categories via the interactive legend
• Custom Categories: Create, rename, and delete categories to organize your schema
• Color Customization: Assign custom colors to categories for better visual distinction
• Table Organization: Easily move tables between categories using the category editor
• Auto-Assignment: New categories are automatically assigned distinct colors

Sharing & Collaboration

• Shareable URLs: Generate compressed URLs that encode both your schema and view state
• View State Preservation: Shared links preserve selected categories, layout algorithm, and view mode
• One-Click Sharing: Copy shareable links to clipboard with a single click
• Format Support: Compatible with SQL and Mermaid schema formats
• Backward Compatible: New URLs work in older versions, gracefully degrading if view state isn't supported
