Heterogeneous environment with conversion from single to multi-frame objects

Conversion

Why conversion

• Enormous archive of Classic objects

• Supports the transition from Classic to

Enhanced environment

• More often used on different places

• Transportation needs speeding up

• Leverage most of the benefits

Conversion

Requires

• Conversion done by independent

stations

• Build knowledge for various vendors

• Relaxation of Manditoriness

Conclusion

• Huge potential benefit for using Enhanced

objects

• Support is growing

• Pushed by

• Increased Interoperability

• Increasing datasets

• Potential Speed gain

• Higher availability

• Coming conversion definition
