Format Details
DTA
DTA is the native binary data file format for Stata, a statistical analysis package widely used in economics, epidemiology, and social science research. It stores complete datasets along with variable labels, value labels, missing value indicators, and display formats that preserve the full analytical context. DTA files can contain millions of observations and thousands of variables, making them suitable for large survey and panel datasets.
Parquet
Apache Parquet is an open-source binary columnar storage format designed for efficient analytical data processing across the big data ecosystem. Its columnar layout enables excellent compression ratios and fast query execution when only a subset of columns is needed. Parquet is the de facto standard format for data lakes and is natively supported by Apache Spark, Hadoop, Presto, Snowflake, and most modern data processing platforms.
