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.
