Welcome to the PADX live demo!

PADS-Galax (PADX) seeks to combine the powerful XQuery processing of Galax with the data processing capability of PADS. The overall idea is to be able to start with input flat files, and query them using XQuery. The PADS-Galax software takes care of the middle step for you - converting the input flat files to XML.

The menu on the left lists three PADS-Galax examples that you can execute using PADS-Galax.

Each example includes three basic components:

PADS input file. This file describes each record in the input data file. It includes the data types (of each field), the separators between each field, and the name of each field.
An XQuery query. This XQuery query will be applied to the XML produced by the PADS front-end of PADS-Galax. Your final output will thus result from the execution of the XQuery query; you won't see the intermediate XML.
Input data. These are the input data records which will be processed by PADS, sequentially. You may change, add, delete, etc., in order to study PADS's handling of the input data.

After you are satisfied with the XQuery query and the input data, run PADS-Galax. You may run PADS-Galax as many times as you like. Please experiment by changing the XQuery query as well; this will show you how XQuery operates on the XML which results from the first stage of processing.
