Data Extraction from UML models

Model is a conceptual representation of any system. Models provide a clear view of the system under development. Models acts as an intermediate representation between the specification and the final code. Unified Modelling Language (UML) is a language used to represent the models in Object Oriented Systems. This paper aims at extracting the data from UML models which forms the first step during generation of test cases from UML models. In order to process the models, firstly the data within needs to be extracted and represented using a data structure. The proposed approach provides a technique to extract the data from one of the UML models i.e. Activity Diagram so that the data can be used for further processing
