☕ 🏗️ ORM Models in TuskLang Java
🏗️ ORM Models in TuskLang Java
"We don't bow to any king" - Build models like a Java architect
TuskLang Java provides sophisticated ORM model management that integrates seamlessly with Spring Boot, JPA, and modern Java patterns. Create, configure, and manage your ORM models with enterprise-grade performance and flexibility.
🎯 Overview
ORM models in TuskLang Java combine the power of Java JPA technologies with TuskLang's configuration system. From entity mapping to complex relationships, we'll show you how to build robust, scalable ORM model systems.

🎯 Best Practices
1. ORM Model Design Patterns
// ✅ Use appropriate entity mapping
- Use @Entity for persistent classes
- Use @Table for table mapping
- Use @Column for field mapping
- Use @Id for primary keys// ✅ Implement proper relationships
- Use appropriate relationship types
- Set correct cascade options
- Choose appropriate fetch types
- Maintain bidirectional relationships
// ✅ Use lifecycle callbacks
- Use @PrePersist for creation
- Use @PreUpdate for updates
- Use @PreRemove for deletion
- Use @PostLoad for loading
// ✅ Implement validation
- Use Bean Validation annotations
- Implement custom validators
- Validate business rules
- Handle validation errors
2. Performance Optimization
// 1. Query Optimization
- Use appropriate fetch types
- Implement batch loading
- Use JOIN FETCH for eager loading
- Monitor query performance// 2. Caching Strategy
- Use second-level cache
- Implement query cache
- Use collection cache
- Monitor cache performance
// 3. Batch Processing
- Use batch operations
- Implement batch size optimization
- Use bulk operations
- Monitor batch performance
// 4. Memory Management
- Use lazy loading appropriately
- Implement proper cleanup
- Monitor memory usage
- Optimize entity lifecycle
