Understanding Gravity Forms Database Architecture

Before diving into advanced connection techniques, it’s essential to understand how Gravity Forms organizes data at the database level. This knowledge will inform your design decisions and help you create more efficient, scalable systems.

Core Database Structure

Gravity Forms uses a carefully designed multi-table schema that separates concerns while maintaining data integrity:

• wp_gf_form: Stores basic form information (names, creation dates, status)
• wp_gf_form_meta: Contains comprehensive form metadata (field definitions, conditional logic, display settings)
• wp_gf_entry: Holds submitted entry data (timestamps, user information, status indicators)
• wp_gf_entry_meta: Stores individual field values with normalized structure
• wp_gf_entry_notes: Manages comments and status updates for workflow tracking

This normalized structure provides several advantages for relational database applications:

• Efficient storage of variable-length data
• Support for complex field types with multiple components
• Simplified querying for specific field values across entries
• Flexibility for custom field types and add-on functionality

Entry Relationships and Connections

Gravity Forms supports multiple relationship models that enable sophisticated data connections:

One-to-Many Relationships: A single parent entry connects to multiple child entries (e.g., a company registration with multiple employee records)

Many-to-Many Relationships: Entries from one form can associate with multiple entries from another form (e.g., students enrolling in multiple courses)

Cross-Form References: Entries can reference and depend upon data from other entries, creating hierarchical data structures
