Technical Architecture
A deep dive into the database design, workflows, and technical structure that powers V.E.T.S.
Database Architecture
Core Tables
Animals & Herds
- Individual Animals: Complete profile including name, breed, registration, DNA, microchip
- Herds/Groups: Logical groupings of animals with shared characteristics
- Relationships: Lineage tracking (sire, dam, offspring)
- Ownership: Historical and current ownership records
Physical Items
- Inventory Management: Track quantity, location, condition
- Item Types: Equipment, medications, feed, IoT devices
- Associations: Link items to specific animals or herds
- Transactions: Purchase, sale, usage history
Actions
- Action Types: Veterinary, training, competition, husbandry
- Type-Specific Tables: Custom data structures for each action type
- Action Chains: Link actions in sequences (e.g., pre-op ? surgery ? post-op)
- Scheduling: Planned vs. completed actions
Knowledge Base
- Tree Structure: Hierarchical organization with parent-child relationships
- Content Nodes: Store AI-generated and expert-validated information
- Versioning: Track changes and improvements over time
- Permissions: Control access at the node level
System Components
Data Layer

- Stored procedures for business logic
- Views for complex queries
- Triggers for data integrity
Application Layer
- Web-based interface
- RESTful API endpoints
- Real-time collaboration
- Mobile-responsive design
AI Integration
- LLM content generation
- Expert validation workflow
- Content caching and reuse
- Continuous learning
IoT Integration
- Device registration
- Real-time data streaming
- Alert triggers
- Data visualization
Key Design Patterns
1. Entity-Relationship Model
Every entity in V.E.T.S. has a unique identifier (GUID) that remains stable across the system lifetime. This allows for:
- Reliable references even as data moves or changes
- Merge and synchronization across systems
- Audit trails and historical tracking
2. Tree Navigation Structure
The knowledge base uses a recursive tree structure where each node can have:
- ParentRef: Immediate parent node
- RootRef: Top-level ancestor for quick traversal
- SortOrder: Position among siblings
- Type: Defines behavior (container, webpage, action, etc.)
3. Extensible Action System
Actions are implemented through a base table plus type-specific extension tables:
- Base Actions Table: Common fields (date, animal, user, etc.)
- Type-Specific Tables: Additional fields for each action type
- Custom Programming: Type-specific business logic and validations
- Action Chains: Link related actions into sequences
4. Permission System
Granular control over who can see and do what:
- Role-Based Access: Owners, veterinarians, trainers, staff
- Entity-Level Permissions: Control access to specific animals or herds
- Action Permissions: Who can perform or view specific action types
- Knowledge Permissions: Control access to knowledge base sections
Data Flow Examples
Veterinary Procedure Workflow
- Schedule: Create task for upcoming procedure
- Prepare: System suggests required items and preparation steps
- Execute: Record procedure details in action-specific table
- Document: Attach photos, notes, findings
- Follow-up: System suggests next actions based on findings
- Knowledge: Link to relevant protocols and best practices
AI-Enhanced Knowledge Creation
- Request: User asks for information on a topic
- Check Cache: System looks for existing validated content
- Generate: If needed, LLM creates initial content
- Review: Expert reviews and edits the generated content
- Validate: Approved content saved to knowledge base
- Reuse: Future requests use the validated content
Performance & Scalability
- Indexing Strategy: Optimized indexes on frequently queried fields
- Caching: Intelligent caching of knowledge base content
- Pagination: Large result sets loaded incrementally
- Lazy Loading: Tree branches loaded on-demand
- Async Processing: Heavy operations run in background
Security
- Authentication: Secure user authentication and session management
- Encryption: Data encrypted in transit and at rest
- Audit Logging: Complete trail of who did what and when
- Backup: Regular automated backups with point-in-time recovery
- HIPAA Consideration: Architecture designed for compliance requirements
