Core Architecture

Ruhanir ERP Platform Overview

Ruhanir ERP is a multi-tenant enterprise resource platform. It serves education, healthcare, retail, hospitality, gym, and professional brand organizations from a unified codebase while enforcing cryptographic tenant boundary separation at the database layer.

System Boundary Guarantees

  • Database Partitioning: Relational tables partitioned by tenant_id for scoped queries.
  • Edge Routing: Cloudflare edge runtime rewrites subdomains (slug.workbookbd.com) to dedicated tenant views.
  • Stateless Authentication: Cryptographically signed JWT tokens carrying user role and tenant context.

High-Level Request Lifecycle

Every incoming HTTP request resolves the tenant identity from either the subdomain or verified custom domain before executing any business logic.

2. Edge Router:     Extracts slug 'ironforge' from Host header
3. Database Lookup: Validates active tenant in public.tenants_public
4. Tenant Context:  Resolves session tenant_id for relational data query
5. Response:        Renders GymLanding with scoped IronForge data only
