FieldAssist SaaS Platform V2 ER diagram models a three-layer multi-tenant architecture separating global platform governance, organization-level tenant isolation, and field operations logistics. The global layer manages organizations, super-admins, security audit traces, and master capabilities; the tenant layer enforces role-based permissions, user management, and reporting hierarchies within isolated schemas; the operational layer tracks clients, visits, geofence validation, location monitoring, breadcrumb telemetry, and attendance. This architecture demonstrates SaaS best practices: schema-per-tenant isolation for data privacy, capability-based access control for fine-grained permissions, and comprehensive audit trails for compliance. Fork this diagram on Diagrams.so to customize tenant isolation strategies, add new operational entities, or adapt role hierarchies for your field service use case. The geofence_validated and location_monitoring tables exemplify how field operations integrate real-time location data with attendance verification.
