Supporting Rapid Application Development on Symbian Platform

Programming for the Symbian OS assumes that developers invest particular and uncomman work, therefore the development lifecycle is rather longer and the costs usually higher than these of common C++ software development. Dealing with user interface, database or communication, programming is not so straightforwoed as excepted. However an appropriate developer tool can be more efficient and solve the designing and programming difficulties. In this paper we will introduce a rapid application development tool set on the Symbian OS. We model the user interface and the statechart of the mobile applications with anovel tool (Visual Modeling and Transformation System). After this design phase source code can be generated. We describe a class library that helps the programmers or code generators to produce Symbian source code that is easy to read and maintain.
