Hi @snowmonkey for your response, my project has to parts a mobile application and web application, the mobile application is being used by different users to scan physical items such as cups or balls which have qrcodes printed on them, and after scanning the item, the app queries the database and check to see if an item is in the database or not, after that process the results are returned to the user. web application is used for entering details of different items by into the database. I hope this clear enough and sorry for the long answer I hope I can get some help on my problem thanks!
