__________________ (Type your name here to certify)
You are not required to test your
sql and pl/sql code, but you can do it if you wish. I will not penalize you for
any syntax errors. You must have the correct logic.
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:
Code to create all three tables, constraints, insert
statements. (10 points)
Code for the first trigger (10 points)

points)
Code for the second trigger (10 points)
Test cases and expected results for the first trigger (30
