Clarification regarding dataset given in project 3

Hi, I need some clarification regarding case study 1 dataset. In dataset we only have 8 records given. But in the below question it was asked to calculate for 30 days which means last 30 records I guess. Percentage share of each language: Share of each language for different contents. Your task: Calculate the percentage share of each language in the last 30 days? So how can we proceed with creating database. Should we create only for the given 8 records or is there any information that could you give us related to this dataset..
