The purpose of this project is to scrapped PDF file. We have our system integrated with captive system which generally parsed all the information from the PDF which is being scanned by user. This project is for US based Insurance company where all the document related to insurance is scrapped by Captiva based on template provided and our responsibility is to check the status of document and also get all the raw data generated and persist in database. We developed UI based on user requirements and show all the status as well as parsed data. This UI is part of big project which is already been developed by the User where user upload the file and it been immediately parsed and our system get all the raw data and our system analyze and validate the data and show in next screen of the user. User is allowed to change the data.
