project 3 Case Study 1

In the project 3 Case Study one, there are only 8 records, which feels inadequate to complete the tasks. Meanwhile when I was checking the guide video for the Case Study 2, it is mentioned that the case study 1 is a sample data and you are supposed to insert more data on your own. This is not mentioned anywhere in the project. So, I'm I supposed to create new records or just go with the available data. Need some clarity on this
