ExPDA – Excel Publish and Display Application

ExPDA has been designed by DTS for ANY organisation that needs to take real-time data into Excel, add value to it, and publish it back out to a set of users, whether internally or externally.  This is all done in the flexible Excel © interface allowing for ease of use and understanding by users. 

For an example of a Bank F/X dealer using ExPDA to provide real time F/X prices to his/her Sales staff click on ExPDA F/X Example.

The use of Excel © as a calculation platform is widely accepted across most organisations. A lot of people working in all sorts of industries create their own spreadsheets with value added data that they use in their daily work routines and some of these are updated on a regular basis each day as different variables change. Many calculations are also based on real-time market data that is sourced from 3rd party feeds.  Often it is desirable to be able to share this "value added" data with other people within your own organisation or with clients and ExPDA works specifically with Excel to enable users to share their data in real-time with other permissioned users on your network.

Any users that have been set up with ExPDA will be able to configure any of the cells within any of their Excel workbooks to broadcast the values from within those cells and these will be available to users that have been permissioned to receive the data. An authorised recipient will be able to subscribe to the data and receive updates to that data in real-time whenever the publisher changes the value in the cell or when it is updated automatically as a result of being based on other real-time market data.

ExPDA comprises a suite of components including:
  • Real-time data feedhandlers
  • Real-time forward handlers to co-ordinate the multiple publish/request instructions
  • Real-time data clients
  • Publish and subscribe facilities built into the Excel interface
  • A comprehensive administration module to control who gets access to what data and to log who is using what data for purposes of license compliance.
