J2EE(JavaTM 2 Platform, Enterprise Edition)의 클라이언트 애플리케이션, 웹 컴포넌트, Enterprise JavaBeans 컴포넌트와 같은 앤터프라이즈 애플리케이션은 개발된 후 컨테이너에 배치되어 실행된다. 이러한 앤터프라이즈 애플리케이션(enterprise application)은 다양한 EIS(Enterprise Information System)에 접근하여 관련된 기능과 데이터를 사용할 필요가 있다. J2EE 커넥터 아키텍처(Connector Architecture)는 J2EE 플랫폼을 다양한 EIS와 연결하기 위한 표준을 정의하는 API 이며, 각 EIS 벤더는 이러한 커넥터 아키텍처의 설계서를 따르는 EISF의 시스템 레벨 소프트웨어 드라이버인 표준 리소스 어댑터(Resource Adaptor)를 제공한다. 커넥터 아키텍처를 구현한 리소스 어댑터를 사용함으로써 특정 벤더의 J2EE 플랫폼에 종속되지 않도록 EIS를 통합할 수 있다. 본 논문에서는 이러한 J2EE 커넥터 아키텍처를 구현한 리소스 어댑터를 애플리케이션 서버를 배치하기 위하여 배치기가 수행해야 하는 배치 단계를 크게 네 단계로 구분하고, 배치구성 활동을 다섯 가지로 분류 및 정의한다,

The performance of Enterprise Architecture (EA) in the Korea's public IT domain produces mixed results and responses. On the one hand, EA earns positive remarks and enthusiasm as a central government-wide IT governance framework with its significant IT budget saving records. At the same time, however, the response to EA at the department and agency level is tainted with disappointment, fatigue, and reluctance. This essay suggests that this is perhaps caused by the sterile lackluster concept of EA Business Architecture employed in the current EA practice of the enterprise. The possibility for liberating and reviving the concept of EA Business Architecture is explored. Various conceptual axes and branches of EA Business Architecture are identified based upon extensive EA field experience and observations, and discussions are made on how the concept of EA Business Architecture can be expanded and amplified on those conceptual axes and branched. The resulting EA Business Architecture conceptualization is consolidated into an illustrative typology for EA Business Architecture. In the end the theoretical and practical implications of the research are discussed along with its contribution and limitation.

Enterprise Content Integration (ECI)is an IT strategy that improves enterprise' competitive advantages by integrating enterprise wide information and content into a unified view, which in turn supports efficient and effective decision making. Content Syndication Systems (CSS) is a solution that implements the ECI strategy. In semi-conductor industries, it is usual that enterprise content is scattered over tens of legacy systems. Therefore, engineers in semi-conductor companies spend a few hours to locate required engineering information on a daily basis as part of their jobs. In this paper, we develop an enterprise CSS system that integrates enterprise wide contents into a unified view that is suitable for semi-conductor industries. For this research, we first define enterprise CSS, then identify their systems requirements. Then we propose an architecture supporting the identified requirements, and present the implemented prototype. One of the most important requirements is the individualized subscription rule setting for engineering information. For this purpose, we developed methods to represent the information properties and subscription rules.

This paper aims to explain the reasons of manufacturing's reshoring (U-turn) and to suggest the supporting law and policy and the utilization of enterprise architecture (EA) in order to attract reshoring manufacturers into port logistics park. First, this paper found the reasons of reshoring reviewing the previous researches. The reasons are 1) advanced country's manufacturing competitiveness in total production cost compared to the emerging countries such as China, 2) the government policies enhancing the reshoring of their enterprise, and 3) the deterioration of management environment of foreign companies in the emerging countries. Second, this paper reviewed the supporting law and policy of korean government for reshoring manufacurers, and suggested the method to attract them into port logistics park. The current law to support the reshoring manufacturers does not have articles about moving into the port logistics park in order to help global trade from outsourcing countries. Finally, this paper provided the method of utilization of enterprise architecture to help reshoring decision making to get their benefit for the future and collaboration among related government departments with the ministry of maritime affairs and fisheries.

The investment on informatization has caused the increase in complexity of IT resources as well as inefficiency of Information system management and redundant investment. Thus, the idea of EA (Enterprise Architecture) was developed in order to manage the IT resources efficiently but the systematical guideline was insufficiently provided in data area.. Because of this, it is necessary to make full use of DRM (Data Reference Model) so we can enhance the sharing and reuse of data between several institutions in public sector by extracting and managing data behind processes. In this study, we recognize the necessity of improvement on data classification which is highly utilized and present the direction for the data classification rethesis.

This paper is concerned with the development of the requirements for railway safety support information systems. The five safety elements at the system level have been modeled based on the enterprise architecture approach. Specifically, the modeling has been carried out as follows. First, the requirements are derived according to EIA-632 process. Also, the possible scenarios on the accident-investigation-support are developed from the help of relevant personnel in the area. The developed scenarios are reflected in modeling the operational and system architectures of DoDAF approach using a CASE tool. From this architecture model, we can easily get the specifications required for the operations. These results can give the improved understanding of the railway safety system to the members of diverse teams and areas working for the system development.

Service Oriented Architecture(SOA) is a flexible structure which does not affect other services even when a specific service is changed. It provides the platform with neutral interfaces independent of any others, where services are loosely coupled in a standard way. While ESB (Enterprise Service Bus) is a key technology for service-oriented architecture, few research and development for ESB has been done. In this paper, we designed and implemented the key components of ESB such as mediation service, message oriented middleware service, operation service, monitoring service, application connection service, and database connection service. The performance evaluation was done by measuring the message processing time for the number of messages with various sizes.

In this paper, a method to generate the extended model automatically on the critical elements in enterprise system based real time distributed architecture as well as the platform specific model(PSM) for Microsoft(MS) .NET platform is proposed. The key ideas of this method are real time distributed architecture should performed with satisfying strict constraints on life cycle of object and response time such as synchronization, transaction and so on, and .NET platform is able to implement functionalities including before mentioned by only specifying Attribute Code and maximizing advantages of MDA. In order to realize the ideas, functionalities which should be considered enterprise system development are specified and these are to be defined in Meta Model and extended UML profile. In addition, after definition of UML profile for .NET specification, by developing and applying these into plug-in of open source MDA tool, and extended models are generated automatically through this tool. Accordingly, by using proposed specification technology, the profile and tools easily and quickly reusable extended model can be generated even though low level of detailed information for functionalities which is considered in .NET platform and real time distributed architecture. In addition, because proposed profile is MOF which is basis of standard extended and applied, UML and MDA tools which observed MOF is reusable.

This paper aims to design and realize movie reservation system based EJB 3.0 enterprise for standardization. Non EJB and the EJB architecture to resolve the problem with benefits to support the new architecture is a lightweight container architecture. This architecture, such as the EJB, but not heavy, to provide all of the architecture is possible. The lightweight container architecture is most often used in business EJB 3.0 is well-known architecture. Therefore, this research has the Non EJB and the EJB to solve the advantages and disadvantages developed to support the latest EJB 3.0 architecture based on the design and implementation of a movie reservation system.
