GlobalTransactionManager (AristaFlow Business Process Platform API)

All Superinterfaces:

ADEPT2Service
```
public interface GlobalTransactionManager
extends ADEPT2Service
```
A GlobalTransactionManager handles transactions globally, this can be either service-specific, spanning several services, spanning several databases or even several database management systems.
In the most simplest case, it just provides a TxManager handling transactions. This handles transactions that span several method calls without having the need to provide the corresponding Connection as parameter to each of the involved methods. By sharing one TxManager by several services (but the very same database), transactions can span several services easily.
