Identification of Design Patterns for Mobile Services with J2ME
InSITE 2008 • Volume 8 • 2008
The functional approach to software development has been used for years and new methodologies have evolved, including, object-oriented approach. Objects are sharing an important part in the software business. They have become the building blocks of many systems whether commercial applications, real-time applications or embedded systems applications. As objects represent an abstraction of the real world, systems modelled using objects can be easily read and interpreted. Design patterns have been used on desktop systems. Today, the trend is towards building applications on small hand-held devices like mobile phones, PDAs or pocket PCs. Due to the limitations of hand-held devices, applications should be optimised and design pattern is the right choice to cater for this need. In this paper, the design pattern chosen for mobile services using J2ME is the One-function structure design patterns. Although it resembles the behavioural design pattern, the One-function structure name has been given because the pattern is made up of other classes and objects and is performing a single task. The patterns have been used in two applications with basic management functions namely add, edit, erase and search and the result obtained proves their re-usability and reliability.
