An SDM file is a TIBCO Statistica workspace. It contains data, nodes, and connections that data analysts use to analyze and interpret data. By default, SDM files do not contain the results of an analysis.

TIBCO Statistica is an analytics suite that data analysts use to analyze data and create predictive models. As they begin analyzing data, analysts drag and drop datasets and processes, referred to as nodes, into a Statistica workspace. Typically, analysts annotate nodes as they add them to explain each node's function. Analysts then connect their nodes and run the composite process they've created to generate an analysis.

An SDM file stores the data, processes, connections, and annotations an analyst has assembled in a Statistica workspace. It does not, however, typically contain the results of an analyst's analysis. So, while analysts can use SDM files to share datasets and processes, each analyst must run the process an SDM file contains themselves to view the process's results.

You can open an SDM file (TIBCO Statistica Workspace) and run the processes it contains in TIBCO Statistica. To open an SDM file in Statistica, select File → Open → Workspace from the program's menu bar. To run the processes an SDM file contains, select Run All from the Workspace window.
