[jboss-user] [EJB 3.0] - Re: History Interceptor

[dhartford]

Hi jc, 
I have not thought about the array scenario...I would imagine that if it is in a relation with another table/entity and both marked for History, it would somehow handle both scenarios.


I know the previous 'Audit' implementation and the 'History' implementation from hibernate both follow a logging approach of just what has changed.  I was looking for a more detailed 'History' so that you could get the state of the data during a specific time.

*particularly useful for applications with, say, Jboss Rules and testing retroactive changes.
*Although logging is more efficient space-wise, researching the 'state' of the data during a specific time is more processor and labor efficient if captured in its full state. However, if a mechism was in place to retrieve the entire entity state from just the logged changes, that would be wonderful.

I would be interested in feedback and comments.

not very interesting example:


  | Address
  | clientId|street|city|state|zip|timestamp
  | 32|44 roy drive apt 2|bumsville|ZZ|99999|apr 06
  | 
  | AddressHistory
  | autoId|clientId|street|city|state|zip|timestamp
  | 1|32|345 summerville road|bumsville|ZZ|99999|jan 04
  | 2|32|44 roy drive apt 1|bumsville|ZZ|99999|feb 06
