Web Application audit trail

Question

I am performing audit trail for a web application of the user id login who perform insert/update/delete of records.

There are no issues for insert / update triggers. However, for delete trigger the database would not know the "user id" who perform the delete.

I am using oracle database and jdbc with connection pooling.

How do I pass the "user id" to the delete trigger?

Answer 1

Take a look at Audit4j . It supports out of the box support for application auditing.

Answer 2

Are you using JPA? If so, are you using EclipseLink? If so, can this be done without triggers?

If you answered yes to all three answers, have I got an answer for you. Take a look at EclipseLink's History table feature . I've used this in the past successfully to implement an audit trail.

Otherwise, consider "soft deletes" by having a Status column. Instead of physically removing the row from the database, you simple set the row status to disabled. In your Select queries, just add "and where status != disabled."
