💡 Model Answer
Common data file types include:
- CSV (Comma‑Separated Values): plain text, easy to read, but no schema or compression.
- TSV (Tab‑Separated Values): similar to CSV but uses tabs.
- JSON (JavaScript Object Notation): hierarchical, self‑describing, good for semi‑structured data.
- Parquet: columnar, compressed, schema‑aware, ideal for analytics.
- Avro: binary, schema‑driven, good for serialization and RPC.
- ORC (Optimized Row Columnar): columnar, similar to Parquet, used mainly in Hadoop ecosystems.
- XML: markup language, hierarchical, verbose.
Each format has trade‑offs in terms of readability, compression, schema support, and query performance.
