Modeling Data Integration with Updateable Object Views

Recently, a range of applications of views increases. Views are not anymore tightly related to classical databases – there are proposals to use them as means of data transformation and integration in distributed environment. Despite many aspects of view applications, there is still lack of suitable graphical notation that would help designers by providing clear notions from the very early stage of system development. Therefore, our objective is to propose a suitable extension of UML supporting the design process. We focus on modeling object-oriented updateable views in the context of data integration. We believe it is one of the most prominent appliances of views. The paper describes assumed general features of updateable object views and fits them into an object-oriented metamodel. Based on this, we suggest the necessary view-specific notation elements, and present some examples of view modeling.
