## Architecture
57

58
Spring Boot Starter Parent operates as a Maven parent POM providing:
59

60
- **Dependency Management**: Inherits from spring-boot-dependencies for consistent versioning
61
- **Plugin Management**: Pre-configured Maven plugins with sensible defaults
62
- **Property Configuration**: Standard properties for encoding, Java version, and compilation
63
- **Resource Processing**: Automatic filtering of application configuration files
64
- **Profile Support**: Native compilation and testing profiles for GraalVM
65
- **Build Conventions**: Consistent packaging and deployment configurations
