Bullhorn Data Fundamentals

Understanding Schema in Bullhorn

In the context of Bullhorn, a schema is essentially the structural blueprint that defines how data is organized, stored, and retrieved within the system. It dictates how various data fields (like candidate information, job orders, placements, etc.) are related to each other, the data types allowed, and the rules for how data can be entered, updated, and queried.

Think of a schema as the underlying architecture that ensures data flows smoothly between different modules in Bullhorn without breaking or causing inconsistencies.

Key Components of a Schema in Bullhorn
  1. Entities and Fields
    • Entities: These are the core objects like Candidates, Jobs, Contacts, Companies, and Placements.
    • Fields: Each entity contains multiple fields, such as First Name, Last Name, Email, and Phone Number for a Candidate entity. Fields can have different data types (text, number, date, boolean, etc.).
  2. Field Mapping
    • Field mapping defines how information is transferred between Bullhorn and other integrated systems or data sources. It ensures that the right information ends up in the correct fields.
  3. Data Relationships
    • The schema outlines how entities relate to each other, enabling linked information between contacts, companies, and job orders.
  4. Custom Fields and Extensions
    • Bullhorn allows the creation of custom fields to capture additional information beyond the default schema.
  5. Validation Rules and Constraints
    • Schemas include rules to prevent invalid or duplicate data entries.
  6. API and Schema Access
    • The Bullhorn REST API provides endpoints to access schema information, enabling developers to query available fields, data types, and relationships.
Why a Proper Schema Matters for Staffing Firms
  1. Efficient Data Management
  2. Improved Data Quality
  3. Seamless Integrations
  4. Enhanced Reporting and Analytics
  5. Compliance and Security
Common Challenges and Best Practices

Challenges:

  • Inconsistent field usage due to legacy data or manual errors.
  • Lack of standardized field mapping causing integration failures.

Best Practices:

  • Regularly audit your schema.
  • Standardize field naming conventions.
  • Use validation rules.

A well-structured schema is the backbone of effective data management in Bullhorn. By understanding and optimizing your schema, you can ensure cleaner data, smoother integrations, and a more productive recruiting process.
