Exp	This Document Management Site worked as a PDF publishing site. In the publishing site users uploaded Word, Excel or PowerPoint documents and these documents would get converted into PDF files and get published to another site. The published PDF files were disabled for saving and printing for security reasons. The application is used by thousands of users and several documents are uploaded to the system on a daily basis. On publishing failure the user receives an intimation about the failed document and reason of error. The documents are hosted in hierarchy of folders with each folder having unique permissions.
