SAS7BDAT is a proprietary binary data storage format developed and maintained by the SAS Institute for use within its statistical software ecosystem. It is primarily utilized for managing structured datasets, metadata, and large-scale data processing across industries such as clinical research, finance, and data science. While the format poses minimal security risks, its closed-source nature often necessitates the use of specialized software or dedicated libraries for cross-platform data accessibility.
