Assignment 1

Create a table with two columns. Name the table First Initial _ Last Name (e.g. John Dow
will create table j_dow). You have to audit all DML statements on your table. To do this you write two triggers:
1. To log any DML statements that users might run on this table. The results must be stored in the First Initial _ Last Name _ Log table (e.g. John Dow will create table j_dow_log).
The table should have unique event ID, values for both the Oracle and the system user who ran the query, the time it was executed and the type of DML query user ran.
2. To capture any data that was changed in the table. The results must be stored in the First Initial _ Last Name _ History table (e.g. John Dow will create table j_dow_history).
The table should reference the event ID from the log table, and store both old and new values for both columns.
What to submit: Name this file according to submission guidelines and include the following answers:
