<p>This assignment has been performed at location and commissioned by Attendit</p><p>AB in Jönköping. The task has been to develop a client/server system to access</p><p>data stored in SQL databases where the client application is developed to run on</p><p>regular cellular telephones. The importance has been to develop as reliable mobile</p><p>communication as possible. The functionality that is demanded upon the mobile</p><p>communication is:</p><p>• Secured for future versions</p><p>• Interoperability</p><p>• Data should not be bugged, modified or disappear</p><p>unnoticed</p><p>• Resource efficient</p><p>We have achieved these demands by developing our own protocol that is on top of</p><p>the TCP protocol. The difficulty with the development has been to take in mind</p><p>the limited resources of the mobile phones regarding storage, memory and CPU.</p><p>The result of this task is a working system with a belonging database which has</p><p>stable mobile communication as foundation. Server and client is well structure so</p><p>the system easy can be extended with new different calls to the database.</p><p>In hence of confidentiality the real system is not presented in this report. Instead</p><p>we will describe fictitious scenario to exemplify the resolutions to the problems</p><p>that we have identified.</p>
