Does anyone have any recommendations on auditing data changes on several
tables? I want to keep before and after data along with username/timestamp.
I'm thinking of a DML trigger on each table and each with its own audit
table? Or what about a single audit table (using TO_CHAR to convert all
non-character data into the BEFORE and AFTER columns; only CHAR, VARCHAR2,
DATE and NUMBER datatypes are used). That should be slightly more generic.
Either way it seems a bit messy. Anybody got a better idea? (This audit
trail has to be readily visible to the users - ie. a table - Log Miner
isn't really practical).
Many thanks for any suggestions.
- Bill.
