1- You can check attribute names from each table in DBF11 by running for example:

 desc dbf11.Member;

 desc dbf11.Agent;

 desc dbf11.Producer;

Because some attribute names in the tables might be slightly different from those in the assignment blue sheet, please make sure to verify the attribute names first before querying the tables.

This way, you check the real data set first before validating your queries.

2- For question 1d:

Display the month(s) in which the number of entries for the awards is higher than the monthly average of entries for the current year.

The 'number of entries' refers to the FILM entity, and the montly average comes from the 'entry_date'. This question is referring to the number of films that have been entered into the award system.

3- INSTRUCTIONS for TASK 3 FILES

- You need to run (or cut and paste) 'task3-build.sql' on your own oracle account to create the required tables for question 3

- You then need to populate the tables with data by running (or cutting and pasting) 'task3-populate-before-trigger.sql'

- You can then implement the trigger questions for the assignment.

- You need to submit your spool for trigger questions by showing the results of executing (or cutting and pasting) 'task3-populate-after-trigger.sql'.
