This research introduces the architecture of managing products based software. There are many of the architectures for managing products using software instead of manpower. In case of MVC and existing architectures, The architectures transfer redundant data so the architectures cause a problem that unnecessary data moved. This research presents VMDC(View, Model, Dispatcher, Controller) architecture to solve the problem. Dispatcher of VMDC grasps necessary data and reconstructs objects to efficient transferring data. This research shows usecase that designed VMDC(View, Model, Dispatcher, Controller) and demonstrate efficiency of VMDC(View, Model, Dispatcher, Controller) together. after demonstration this research present with next research.

Layered Architecture is a kind of nodule decomposition techniques, which decomposes a program by generality This paper proposes a ]aver based method for recovering layered architecture from object-oriented program and checking conformance against architectural document. To specify the rules for layered style in object-oriented program, we define a partially ordered set on modules by module use relationship and module layer relationship by module override relationship. The meaning of module layer relationship is explained with an example from design patterns. Steps to recover layered architecture from program are described and a metamodel for the recovery is proposed. Architecture recovery is performed on source codes from open-source software project, and the implication of parts that do not conform to its architectural document is discussed. As a result of checking, it is pointed out that, although the parts are considered allowable exceptions of layered architecture, their modifications should be controlled carefully.

최근 서비스 지향 아키텍처를 적용한 많은 시스템들이 개발되어 왔고 그에 따라 서비스 지향 아키텍처에 대한 관심도 증가하고 있다. 하지만 여태껏 연구되어왔던 주제들은 전체 아키텍처의 효율적인 구성 및 개발 프로세스 구축에 초점을 맞춘 반면, 데이터 프레임워크를 보다 효율적으로 비즈니스 프레임워크와 분리하는 데 초점을 맞춘 연구는 부족하다. 이에 우리는 실 서비스되고 있는 대용량 서버 관리 서비스를 서비스 지향 아키텍처로 전환하고 그 중 데이터 프레임워크를 보다 추상화시키고 비즈니스 프레임워크와 느슨한 결합을 이룰 수 있도록 하는 연구를 진행하였다. 본 논문에서 제안하는 데이터 프레임워크는 실시간 데이터 전송에 유리한 트리 구조의 데이터를 사용자가 정의한 규칙을 기반으로 비즈니스 프레임워크의 다양한 비즈니스 로직에서 효율적으로 활용할 수 있는 다양한 형태의 데이터로 바꿀 수 있는 계층을 제공한다. 또한 이러한 계층에 대해 실 서비스에서 활용할 수 있는 정의된 제약조건 하에서 실험을 진행하였고 그 결과 만족스러운 성능을 보이는 것으로 나타났다.

Most of electronic medical record systems which have been built in Korean hospitals are based on source oriented medical record approach. These systems hardly satisfy diverse objectives owing to the innate imperfections in system architecture and development methodology. Thus, the hybrid of source oriented and problem oriented approach is highly desirable. The purpose of this study is to present an architecture and methodology required to construct hybrid electronic medical record system and to develop a prototype based on them. Analyzing the clinical processes and data requirements of problem oriented medical record approach we developed a software process model as weel as an architecture model which consists of legacy system, clinical data repository, problem list database, prospective plan database, user interface, and synchronization procedures.

To develop multi-tier model or distributed architecture based distributed application needs to consider various aspects such as division of role between web-designer and software developer, defining entity and its usage, database connection and transaction processing etc. This paper presents DONSL(Data Server of Non SQL-Query) architecture that provides solution to above aspects through web-tier object modeling. This is the architecture that guarantees the transaction processing and performance between web-tier and DBMS through simplified usage of query logic property. This new conceptual framework also solves enterprise site implementation problems simplifying tier, and removing DAO(Data Access Object) and entity.

According to change of software development technique as design pattern, component based development etc.., web server development part is applied activity to fit in various user requirement. Especially, EJB as sewer side component model much researches and introduce by easy and various development support. Also, component composing techniques is receiving many interests by easy and efficient application way that architecture based C2 style architecture with message handling. But, in case of EJB component that can not cail thread, C2 framework modification is unavoidable for component composition by C2 style architeccture. For this, we propose techniques to use Adapter pattern to be one of structure pattern among pattern. That is, did so that component composition by C2 style architecture may can consist changing to be able to call thread function in EJB by Adapter pattern.

As the important of software quality has being emphasized, the studies on software architecture also have being performed actively. On the other hand, due to the diversification of Smartphone platforms, the effort was increased to develop the application for supporting those multiple platforms. However several solutions are suggested to reduce the effort, and a representative solution is FireMonkey framework. In this paper, we represent the FireMonkey framework using ACME which is a language to describe software architecture. Such representation can provide the guideline to develop the application for the multiple platforms. Also it supports the information of that which perspectives are critical to develop such applications.

Modeling and Simulation techniques are useful to construct executable battlefields and forces on computers, and have been utilized to analyze effectiveness of weapon systems in the computerized war environment. However, most weapon simulations so far have exhibited low reusability and extensibility, since they have been developed for specific simulation objectives with different structures and simulation engines. In this paper, we identify requirements for defense modeling and simulation activities and propose a simulation engine to support the identified requirements. We define the software architecture of the proposed engine, in a way to efficiently provide usability, component-based reusability, interoperability, and reuse-based development.

The purpose of this study is to develop an efficient BIM-based FM(Facility Management) system architecture to integrate the heterogeneous solution data related to FM. The heterogeneous solution data can be an FM system, asset management system, or facility sensor database systems, as well as files created by a modeler. In this study, we define the consideration for the external heterogeneous data integration related to BIM-based FM and propose the methodology. To implement it, trends in related studies were reviewed and general use cases of BIM-based FM were derived to develop the architecture for the integration between BIM and the heterogeneous solution data. The component architecture was designed to implement the use cases, and the schema was developed for the prototype by using the proposed architecture.

디지털 경제로의 전환에 따른 디지털 부하의 출현과 고품질, 고신뢰도의 전력요구, 거대장치산업과 분산형 네트워크의 조화, 수요자의 역할 변화 등 전력산업의 패러다임이 변화되고 있다. 이러한 전력산업의 변화는 최종소비자의 디지털 부하에 기인하여, 기존의 단순 검침기능으로만 활용되던 전력량계가 소비자 서비스를 위한 게이트웨이로 변모되며, 소비자내 전력기기와 상호 연동되고, 분산된 신재생에너지와 연계된 배전망 및 자가 치유형 전력망으로의 변화를 가져올 것이다. 그러나 현재의 전력시스템은 과거 100여 년간 산업사회를 지향한 하부구조를 지니고 있어 디지털 사회의 요구에 부웅하기 위해서는 새로운 전력시스템이 요구되고 있다. 이를 위해 최신의 정보기술을 적용한 개방형 통합 전력시스템 구축에 대한 연구가 진행중이다. 본 논문은 개방형 통합 전력시스템의 기반이 되는 아키텍처 개발에 대한 연구동향과 아키텍처 개발 방법 및 네트워크 요구조건에 대하여 소개한다.
