Workflow best practise? Comments please (was Shark engine persitsted java variables)

Hi Riccardo,

I attended a workflow course a few years ago and this is what was 
recommended:

The work flow engine holds the "index" data used to manage the work flow.

Anything that needs to be recorded in the longer term would need to be 
recorded outside the work flow database in
the "real" application.

The "index" data in the workflow engine would be purged from the 
database from time to time to keep the engine performing efficiently.


For example, just the order number and what ever data is required to 
guide an order through a work flow would be
in the work flow system rather than all the details of the order. The 
full details of the order would be in an order management 
system/database. and tool agents and client apps would access/update 
that data as part of processing the work flow.
"Application" specifc history information can be recorded in the order 
management system.


Comments ?
