Analysis And Optimization The The Frame Of The Calendar That Based On Qtopia

The Qtopia platform is made by Trolltech, which based on Qt. It can be customed environment, and it has GUI. The same case between Qtopia based on Linux and UIQ and Series 60 based on Symbian.Qtopia is low price,which is based Qt/Embedded. In conclusion, more and more companies use this platform to develop mobil phone software.Trolltech give all the source code of Qtopia, which can be customed by these companies. These companies can develop customed function base on the platform.In fact, developing mobil phone software is a difficult problem. It must redesign and rebuild the frame of Qtopia, including all the parts of Qtopia, therefore, analyse the frame of Qtopia is a very important job for researchers.Calendar is an inportant part of Qtopia,which can give a user a hint to do something.However, I can't find any public resource about Qtopia in our country, which keep it in the dark, not alone abroad .In a word, it is great useful to alanyse the frame of calendar.The contributions of this paper are as follows:(1) Introduces Qtopia and Calendar in detail;(2) Analyse the Qtopia communication mechanicsm;(3) Analyse the frame and database of calendar in detail, and gives the reason for its low speed and bad effiency,suggests using SQLite to replace XML ,in addition, introduce SQLite, which refers to the syntax,good and bad virtue,etc.(4)In the end of this paper,a feasible scheme and relevant algorithms is appeared for optimized calendar.
