Altair® Panopticon


Creating Data Extracts

One of the methods in accessing data is by retrieving only the required results into memory, by querying on demand, pushing aggregation and filtering tasks to underlying big data repositories, or queryable data extracts.

This is commonly known as a ROLAP implementation, where the product is dynamically writing data queries to the underlying data repository and retrieving aggregated and filtered datasets. Given the on-demand nature of this method it is more suitable to exploratory data analysis but requires dynamic query generation.

Data extracts are created in the server administration environment. These server-based data extracts can then be retrieved and used through the Panopticon Data Extract connector.


Data Extract Property



Data extract name.


Data connector used in the extract.


Number of rows of the data extract.


Number of columns of the data extract.


Number of cells of the data extract.


Status of the data extract. Values include IDLE or RUNNING.

When saving a new data extract, it is first run and the status changes to RUNNING. Consequently, the Refresh Data icon is disabled. When the data extract is complete, the status changes to IDLE and the Refresh Data icon is enabled.

Last Updated

The Date/Time when the data extract is last completed or updated.
