AN INTEGRATED GUI-BUSINESS COMPONENT MODELING METHOD FOR THE MDD- AND MVC-BASED HIERARCHICAL DESIGNS

Due to complex applications, such as the reactive system, the importance of graphic user interface (GUI) component modeling has increased. The existing GUI modeling methods, however, do not focus on hierarchical GUI and business component modeling based on the MDD and MVC patterns. Furthermore, there is a lack of systematic component-mapping mechanisms integrating GUI and business/DB component modeling, which consequently makes it difficult to establish a GUI component modeling process integrated with business tasks and ultimately deteriorates the reusability of GUI-business application models. This paper proposes a layered metamodel and an integrated modeling process that can hierarchically build a GUI-business component model based on MDD and MVC. Towards this end, the GUI metamodel and the component metamodel hierarchically established based on the PIM/PSM (MDD) and MVC styles are first defined. Then a GUI-business component modeling process is constructed based on these metamodels, in three modeling phases. Finally, the result of a case study in which the proposed method is applied to an ISMS system is discussed. With the use of the modeling elements and modeling process of the well-defined metamodels based on MDD and MVC, it is hoped that it can be shown that a systematic and layered GUI-business component model can be established, and that the reusability of the constructed GUI-business model can be maximized.

An Integrated Design Method for SOA-Based Business Modeling and Software Modeling

Service-oriented architecture (SOA)-based system development requires a systematic integration technique for software modeling and business modeling methods that approach the implementation component from the perspective of a business service. We proposes the integrated design method (architecture, metamodel, framework, process) for the integration of component software modeling in business process modeling notation (BPMN) business modeling to service-oriented modeling based on model-driven architecture (MDA) and model view controller (MVC) patterns according to SOA. The integrated architecture is composed of a metamodel and a process framework. The integrated metamodel is mapped to the core modeling elements of the SOA-based extended layered (XL)-BPMN/business process execution language (BPEL)/web service description language (WSDL)/component models, and the conversion profile is defined. For the establishment of the integrated process between business and software modeling, the framework is first defined; using this framework, we apply MDA (CIM: Conceptual Independent Modeling, PIM: Platform Independent Modeling, PSM: Platform Specific Modeling) and MVC patterns to define the integrated modeling process for the three development phases. The proposed modeling process was applied to the design of an online shopping mall system (OSMS). The design models were described on the basis of MDA/MVC according to the layered modeling elements defined in the individual/integrated metamodel and the three modeling phases of the integrated modeling process. The case study demonstrated that the conversion modeling task maintains the consistency and practicality between the SOA-based business and software modeling. The use of this method will make the consistent conversion modeling work between businesses and software convenient with a service orientation, will make it easy to change a business process, and will maximize the number of established reuse models.

An Service oriented XL-BPMN Metamodel and Business Modeling Process

The business based existing BPMN model is a lack of service oriented modeling techniques. Therefore, it requires a layered technique of service oriented business modeling so that can meet the design for a complex application system, developing a system based on SOA. In order to enhance reusability and modularity of BPMN business model, this paper proposes a metamodel and business modeling process based on this metamodel that can hierarchically build a BPMN model. Towards this end, the XL-BPMN metamodel hierarchically established based on MDA and MVS styles are first defined. Then a BPMN service modeling process is constructed based on modeling elements of this metamodel according to the modeling phases. Finally, the result of a case study in which the proposed method is applied to an online shopping mall system is discussed. With the use of well-defined metamodel and modeling process, it is hoped that it can be shown that a service dominated and layered BPMN business model can be established, and that the modularity and reusability of the constructed BPMN business model can be maximized.

A Formal Specification of Reusable Framework of Embedded System

Because embedded system is combined system of hardware and software, we should design by considering elements such as real-time, reactive, small size, low weight, safe, reliable, harsh environment, low cost, and so on. However, those are poorly reflected on current embedded system development. Especially, there is few existed framework-based embedded system development. As a result, there are many internal codes which is not related with system operation in currently developed embedded system, and reusability or variability is not considered into embedded system development. Therefore we propose a formal specification technique using Z language to guarantee completeness or consistency of design of reusability framework proposed for improving reusability of embedded system. Also we assure correctness of framework design by checking Z model through Z-Eves Tool.

A MetaModel for Dynamic Mobile Web Service

Frequent change of mobile applications has become a burden to management of mobile services. Therefore, the development of mobile Web services, which the central management is easy, has increased. Tools which developers, as well as general users can easily develop, have been developed for mobile Web services. However, researches of standardized metamodel for implementing mobile Web service dynamically by general users is the inadequate situation. In this paper, we propose a dynamic metamodel for developing mobile Web services. The dynamic metamodel consists of a mobile Web pages, mobile Web page instance and dynamic connection using XDPL structure. we study a connection metamodel for condition connection, split connection and join connection, and combile entire metamodel, finally. Also, we carry out a case study in order to verify the suitability of metamodel by based on XPDL.

Development of Metrics to Measure Reusability of Mobile App.

Abstract As the number of smart phone users is increasing exponentially, the scale of the future mobile market is expected to be very large. Many mobile applications are developing according to this growth trend. On the other hand,there has been little verification of the quality, such as the reusability or extensibility of the developed mobile applications. In particular, many users have expressed their dissatisfaction in the case of pay mobile applications. Therefore, developed to measure the quality of mobile applications in developing mobile applications. Overall, thedegree of user satisfaction can be improved by realizing the quality verification of mobile applications by applying the proposed metrics.

A Framework for Optimizing System Requirements

A well organized system requirements provide a solid basis of achiving a successful project and are effective methods of communication among stakeholders. We illustrate and propose a `System Requirement Development Framework` to develop correct requirements as a methodical approach. We first organize a `Requirement Development Process` and then establish a `Non-Functional Requirements Principle`. On these basis, we next propose a `Requirement Development Guideline` from a perspective of `Functional Requirement`, `Non-Functional Requirement` and `Triage` in advanced stages. We also verify and evaluate the suitability of our proposed `System Requirement Development Framework` by applying it to several projects.
