A Survey of Model Comparison Strategies and Techniques in Model Driven Engineering

Abstract

This Survey paper shows the recent state of model comparison as it’s applies to Model Driven engineering. In Model Driven Engineering to calculate the difference between the models is a very important and challenging task. There are number of tasks involved in Model differencing that firstly starts with identifying and matching the elements of the model. In this paper we discuss how model matching is accomplished, the strategies, techniques and the types of the model. In this paper we also discuss the future direction. We find out that many of the latest model comparison strategies are geared near enabling Meta model and similarity based matching. Therefore model versioning is the most dominant application of the model comparison. Recently to work on comparison for versioning has begun to deteriorate, giving way to different applications. Ultimately there is wide change among the tools in the measure of client exertion needed to perform model comparisons, as some require more push to encourage more sweeping statement and expressive force.
