ActionScript 3.0 :: Write Back Into Database Using FSCOMMAND?

We are working on a 3rd party application build on Adobe Flash technology to render business dashboards.This application does'nt offer us to generate the whole code rather it's just a drag n drop of charts, text boxes etc components, and then mapping of data. After all of customizing, the application itself generates an SWF file finally.
 
What our requirement is we need to make our dashboard(a falsh file) to write a chunk of data, eneterd by user, back into our database by a user action, like a button click. (Access, MySQL, Oracle or any). Now our application offers the FSCOMMAND function call wherein we can enter the command name and args.
 
Now we need to use this FSCOMMAND function to write back to databases because we believe this is the only option with us within our app. What is the command to write back to a database, and then the arguments. Also, do we need to write any JAVA/VB script for that. Please be informed that our application itself generates the whole SWF file code..all HTML coding. {e.g as we include queryparam, "mapped data", using FSCOMMAND, i can see the whole code generated by the app, the HTML code, wherein I could see embedded Java Script with DO_FScommand statament carrying this queryparam command and args..etc.}
 
Kindly show us the way to acheive this crucial requirement of ours. We are looking for very elaborative answers as we have less expertise with scripts.
