    "content": "**Size:** The dataset has one table, `raw.Iris`, with **150 rows** and **10 columns**. The row count is confirmed by the query result. The column count comes from the dataset card: Id, SepalLengthCm, SepalWidthCm, PetalLengthCm, PetalWidthCm, Species, plus four ingestion-metadata columns (`_ingestion_timestamp`, `_batch_id`, `_source_file`, `_source_system`).\n\n**Time period:** The data does not cover any real-world period. The Iris measurements are observational records of flower specimens, and none of the six data columns holds a date or time. The only temporal column is `_ingestion_timestamp`, which records when the data was loaded, not when the flowers were measured. The query shows all 150 rows were ingested at a single moment (2026-09-30 08:19:50.883547), in 1 batch from 1 source file. So there is no time span to analyse, and trend questions can't be answered from this dataset."
