CASE ANALYSIS

Scenario

Designing a database schema for a multi-tenant CRM used by educational institutions to manage student recruitment and relationships.

Key decisions

  • Used Tenant entity to enforce data isolation across organizations
  • Allowed optional relationships for organizations and courses in deals to support flexible pipelines
  • Applied many-mandatory cardinality for core entities like user-tenant and activity-user to ensure referential integrity

When to reuse this

When building a SaaS CRM with multi-tenant architecture for schools, universities, or any educational entity needing contact and deal management.
