Good day, Just a feedback or personal opinion that might help student to attempt the lab questions or improve the understanding of the question. 1. Dataset to attempt the questions 6 to 11 For question from 6 to 11, it would be helpful if small dataset is provided for student to understand the whole data schema and have a better visualization on data that stored in the tables. For example, in Q7, I do understand that PK is item_id and logically each item_id will have a unique description, however in this table, description column may have same name as it does not check unique value in this column. If it is same name, one might use exact match or one might use wild card to do matching. Cheers

Very good suggestion :) I have upload a file on moodle as well as one under week 4. You need to create all your tables first before you attempt to load data. Once you have created the tables, use the following command to load the data: .read printing-dat.sql Cheers Mehwish
