Connect to your database, and Flock generates populations that match your schema — with realistic demographics, comorbidity correlations, and temporal coherence built in. Output as SQL INSERT (FK-ordered), CSV, HL7 streams, or FHIR Bundles.

​
Key Features

  • Schema-aware — Connects to your database, analyzes the schema, and generates data that fits your table structures
  • Epidemiologically grounded — Age, gender, race, and geographic distributions match real US Census data
  • Comorbidity correlation — Diabetes correlates with hypertension, obesity with sleep apnea
  • Temporal coherence — Admissions before discharges, lab orders before results
  • Family linkage — Realistic household structures and family relationships
  • Multiple outputs — SQL INSERT (FK-ordered), CSV, HL7 streams, FHIR Bundles

​
Use Cases

  • QA and integration testing with realistic volumes
  • Development environment seeding
  • Demo environments for sales and training
  • Load testing with production-scale datasets
  • Training new staff on EHR systems
