In modern world as people travel to different locations, they need to access their documents from different locations. Location independent document access service is more useful. Accessing documents can be done by personal computers, laptops and mobile devices. Also documents can share with multiple users. This system allows users to access their documents in any place without bringing pen drives or external hard drives.
The application server holds users account information as well as documents. The PC application and mobile application runs in each devise synchronize document with this application server. So the application server contain newest version of the documents. When another device communicates with the application server, it provide/synchronize the newest documents. When user don’t have his own device, can directly get newest documents from the application server.
The application server mainly uses PHP scripting, client mobile application uses J2ME technology and client computer application uses Microsoft™ .Net technology.
Retrieving the same document in different devices may be different. Because of mobile devices having limited memory, display screens and processing speeds and this can occur.
