Database Auditing

We are in the process of adding field level auditing of an application to a web based audit and compliance reporting tool. End Users update information in an application via a Windows GUI and command line utilities. The application stores data within a database (MSSQL, Oracle, and/or Sybase). We need the ability to audit/record the changes to determine: -What data (field, value, and table) was changed (old value and new value --> even if it is a new insert) -Who made the change (which is the result of another query as there is only one named user in the database that handles all transactions) -When the change was made -The resulting Audit Detail needs to be stored in a new table/tables in the database for retreival by the reporting tool. -The solution cannot impact performance of the already heavy transactional database -Code will need to be work in all 3 database types (MS-SQL, Oracle and Sybase) - Example: joe_user changed the CMD_LINE field from a value of ‘ls’ to to a value of ‘rm’ in the JOB_DEF Table for JOB_NAME ‘JOB1’ at 18:16:22 on 02/16/2006. Notes: Each record we are interested in is comprised of up to 27 different tables, all linked by a key. There are two types of records. Permenant (which use static table names) and dynamic (which have new tables created daily built with a date stamp). There is a documented schema which describes all tables and their relationships.
