Overview of Software Adaptation Techniques; Guide Adaptation Pattern

Computer systems in general, and applications particularly have evolved considerably from 1991 to 2017. Adapting these applications has become a major challenge that needs to be addressed. New approaches and platforms are emerging to facilitate their adaptation and improve their quality. Conventional approaches have limits to adapt easily, especially dynamically. Knowledge of the software adaptation has helped to address software's problems like the transition to the Year 2000. This transition to the year 2000, which has disrupted the computer world with its enormous budget, is an example of a large-scale adaptation project. The companies with knowledge of software adaptation skills have made an easy transition to the year 2000. Others have had to spend a lot of money, and one reason is the lack of knowledge of software adaptation techniques. This article is a survey and analysis study to identify a set of proven software technical adaptations to help companies address the challenges of adaptation. After a presentation of each technique and the evaluation criteria of these techniques, a result of the evaluation is described. Finally, a classification of techniques has been carried out according to technical and functional criteria. The guide pattern to solve problem of choice Software Adaptation Techniques is the main innovation of the article. The study of dynamic adaptation of application mobile in Cloud ubiquitous and android environment will be the future work to explore.
