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
