dsa demo datasets
Three DuckDB databases and accompanying quantitative problem sets for dsa, an agent that answers data-analysis questions and can provide executable Jupyter notebooks explaining its answers.
Each database comes with 100 evaluation problems, including reference answers and answer schemas. The databases and problems can also be used independently of dsa.
Databases
Online Retail II
Transactions from a UK-based online retailer between December 2009 and December 2011. Around one million invoice lines contain products, quantities, prices, timestamps, customer identifiers, and countries, supporting questions about sales, purchasing patterns, and customer retention.
