Design a Content Management Database (MongoDB)

Design a MongoDB schema for a flexible content management system that handles various content types, media, and publishing workflows.

Functional Requirements

• Store diverse content types (articles, pages, products, events)
• Flexible custom fields per content type
• Media library with metadata and variants
• Content versioning and draft/publish workflow
• Multi-language content support
• Tagging, categorization, and content relationships

Non-Functional Requirements

• Handle millions of content documents
• Support rapid schema evolution without migrations
• Enable full-text and faceted search
• Maintain audit history of all changes

Questions to Consider

• When should you embed vs reference related data?
• How will you handle schema-less flexibility while maintaining queryability?
• What indexing strategy supports your query patterns?
