Open Work of Two-Hemisphere Model Transformation Definition into UML Class Diagram in the Context of MDA

Abstract

Abstract. Model Driven Architecture (MDA) is based on models and distinguish between a system functionality specification and this specification realization on a given technological platform. MDA consists of four models: CIM (Computation Independent Model), PIM (Platform Independent Model), PSM (Platform Specific Model) and code model, all these are parts of the MDA transformation line: CIM->PIM->PSM->code. A PIM model has to be created using a language which is able to describe a system from various points of view, system behavior, system's business objects, system actors, system use cases and so on. Current paper discusses the application of two-hemisphere model for construction of UML class diagram as a part of PIM. Several solutions for determination of elements of class diagram from two-hemisphere model are currently researched and described in the paper. As well as application of the transformations by example of insurance problem domain are presented in the paper.

System Modeling in UML with Two-Hemisphere Model Driven Approach

“…Two-hemisphere approach is already successfully applied for encapsulation of attributes and methods into system classes [7], as well as the definition of relationships between classes is presented in [22]. The ideas presented in this paper are a step forward of the author's investigations in the application of two-hemisphere model for software system development in object-oriented manner and the generation of different elements of system model viewing the system from different aspect.…”

“…There is a set of nodes U= {A, B, C, D, E, F, G}, which is based on the same set of elements of concept model and represents objects, received from the set U', and set of arcs P= {P1, P2, P3, P4, P5}, which represent interactions between objects in a form of methods to perform during object interaction. During transition from G1 to G3 through intermediate model each process and each data flow is transferred into corresponding elements of UML communication diagram [7].…”

“…The investigation of 2HMD approach under the statements of MDA in [7] shows that approach could be applied for generation of several elements of class diagram, namely, to generate class names, attributes, methods and several kinds of class relationships. The analysis of two-hemisphere model proposed in [19] and the application of two-hemisphere model for knowledge architecture development in the task of study program development presented in [6] make us to think that notational conventions of UML communication diagram is more suitable for definitions of formal transformations of twohemisphere model into object interaction and then into class diagram, than the application of UML sequence diagram.…”

“…Hypothetically, the transformation from two-hemisphere model into model of object communication is possible [7]. However, this paper analyzes the possibility to generate all the necessary information for object interaction (especially time component of that) in terms of UML sequence diagram.…”

“…Section III shortly reminds an application of twohemisphere model for identification of object classes and dependency relations between them, which are published in [6] - [7].…”
