Proximity can also export selected subsets of data using the Proximity Database Browser. You can export the set of values for a given attribute, or the data in a selected nested synchronized table (NST) to tab-delimited text files.
It is occasionally useful to be able to use or analyze a set of attribute values in another application. To facilitate this, Proximity lets you easily export the set of values for any attribute to a tab-delimited text file.
Exporting attribute values to tab-delimited text files
The following steps require that you be serving a database using the MonetDB server and running the Proximity Database Browser. See Exercise 4.1 for information on starting and using the Proximity Database Browser.
Display the histogram for the target attribute in the Proximity Database Browser. (See “Exploring Attributes” for information on how to display the attribute’s histogram.)
Click export. Proximity displays the Open dialog.
Navigate to the target output directory and enter a file name for the exported data in the Save As box. You can only export data to a file on the same machine as that serving the database.
Click Save. Proximity saves the exported data in the specified file.
