STF Design Features
File based storage on media:
- Structure of data on physical media is the responsibility of the platform operating system, not the STF
- STF transmittals use can hierarchical directory structure to organize files
In essence, implements a simple persistent object database system:
- STF is intentionally not a full object- oriented database management system
SW Implementation abstracts system services to simplify portability:
- Marshals system resources
- Supports platform specific tuning to enhance performance
