Design a multi-tenant course purchase and delivery system
Design a multi-tenant online course purchasing and delivery system. The system must support multiple "Companies" (tenants), each with "Organizations" and "Members". The platform hosts "Courses", which can have prerequisites. Pricing for courses varies by company. Companies can purchase courses for their members, assigning licenses. New entities (companies, organizations, members) can be created dynamically, and each member must have a globally unique ID. Assume the existence of a course class definition and a function to query prerequisites.
Key design areas include:
- Core APIs: For managing entities, browsing courses, purchasing, assigning entitlements, and checking access.
- Data Model: Addressing multi-tenancy, membership, purchases, entitlements, and prerequisite representation.
- High-Level Architecture: Identifying key services and their interactions.
- Access Enforcement: Implementing course access checks, including prerequisite validation.
- Scalability, Consistency, and Operations: Considering auditing, retries, and idempotency.
Assume high read volume for catalog browsing and access checks, strict correctness for purchases, and reasonable latency for prerequisite queries.
