Hi,
First of all i need to let you know that you will need to do a bit of research inorder to understand what i am saying if you are not familiar with XML/XSLT.
You can use XML,XSLT inorder to do the transformation of your data fetched from database to a PDF file.
Basically you will need to fetch data from the DB and create a xml file dynamically.Then you need to create a XSL-FO file for the formatting and display for your PDF which you can add as a file in any of the package.
