Database Model

Formbricks uses PostgreSQL as its primary database and Prisma as the Object-Relational Mapping (ORM) tool. The database schema is designed to support multi-tenancy, survey management, and response collection while maintaining data isolation between organizations.

​

Entity Relationship Diagram

The following diagram shows the core entities and their relationships in the Formbricks database:

​

Core Models

​

Organization & Project Management

1. Organization
   • Top-level entity for multi-tenancy
   • Contains multiple projects and team members
   • Manages billing and whitelabel settings
2. Project
   • Groups related surveys and configurations
   • Has two environments (production/development)
   • Controls branding and display settings
3. Environment
   • Isolates production and development resources
   • Contains surveys, contacts, and actions
   • Manages API keys and integrations

​

Survey Management

1. Survey
   • Central model for questionnaires
   • Configurable with multiple questions and display rules
   • Supports multiple languages and targeting filters
2. Response
   • Records user answers to surveys
   • Links to contact information when available
   • Supports tagging and notes for analysis
3. ActionClass
   • Defines triggering points for surveys
   • Can be code-based or no-code configurations
   • Links surveys to specific user actions

​

User Management

1. User
   • Represents system users (admins/team members)
   • Manages authentication and preferences
   • Can belong to multiple organizations
2. Contact
   • Represents survey respondents
   • Stores attributes for targeting
   • Tracks survey displays and responses
3. Team
   • Groups users within organizations
   • Controls project access permissions
   • Facilitates collaborative survey management

​

Data Isolation

The database schema ensures proper data isolation through:

1. Organization-level isolation
   • Each organization has its own projects
   • Users can belong to multiple organizations
   • Resources are scoped to organizations
2. Environment-level isolation
   • Separate production and development environments
   • Independent surveys, contacts, and actions
   • Isolated API keys and integrations
3. Project-level isolation
   • Project-specific configurations
   • Separate language settings
   • Team-based access control

​

Schema Management

The database schema is managed through Prisma, which provides:

• Type-safe database client
• Automatic migration generation
• Schema versioning
• Data validation
• Query optimization

For detailed information about specific models and their properties, refer to the schema.prisma file in the repository.

PostgreSQL Database Tables

Formbricks stores all data in PostgreSQL tables. Here’s a comprehensive list of all database tables and their purposes:

Table Name	Description
Account	Stores third-party authentication accounts (OAuth) and their tokens
ActionClass	Defines triggerable events that can launch surveys
ApiKey	Stores API authentication keys for environment-specific access
Contact	Records information about user that can receive and respond to surveys
ContactAttribute	Stores attribute values for contacts (e.g., role, company size)
ContactAttributeKey	Defines available attribute types for contacts
DataMigration	Tracks the status of database schema migrations
Display	Records when and to whom surveys were shown
Environment	Manages production/development environments within projects
Integration	Stores configuration for third-party service integrations
Invite	Manages pending invitations to join organizations
Language	Defines supported languages for multi-lingual surveys
Membership	Links users to organizations with specific roles
Organization	Top-level container for projects and team management
Project	Groups related surveys and environments
ProjectTeam	Manages team access permissions to projects
Response	Stores survey responses and associated metadata
Segment	Defines groups of contacts based on attributes
Survey	Stores survey configurations, questions, and display rules
SurveyAttributeFilter	Defines targeting rules for surveys based on contact attributes
SurveyFollowUp	Configures automated actions based on survey responses
SurveyLanguage	Links surveys to their supported languages
SurveyTrigger	Connects surveys to their triggering actions
Tag	Stores labels for categorizing responses
TagsOnResponses	Junction table linking tags to responses
Team	Groups users within organizations
TeamUser	Links users to teams with specific roles
User	Stores user account information and preferences
Webhook	Manages webhook endpoints for event notifications

Schema Reference

For detailed information about the database schema, including:

• Complete field definitions
• Relationships between tables
