Currently, many companies are trying to be more competitive by implementing the most appropriate software package, called ERP (Enterprise Resource Planning). ERP can support the company's business process. A repository, which can story and retrieve enterprise-wide information, is a key component of such software package. This paper implements an enterprise repository for the ERP. A wellknown repository standard, IRDS (Information Resource Dictionary System), is employed for the repository architecture. A meta schema that can help develop database, business applications, models, and workflow is proposed. To illustrate the practical usefulness, a real-life ERP prototype is built within the framework of the proposed repository.

In traditional approach, enterprise-wide consistent security policy enforcement for applications is very difficult task. Therefore, industry is now moving towards new unified enterprise application security concept that consist of centralized authentication and authorization mechanism. The eXtensible Access Control Markup Language (XACML); an XML-based standard defined by OASIS, is most suitable choice which can support centralized, role based, context aware access control mechanism. It is designed to provide universal standard for writing authorization policies and access control request/response language for managing access to the resources. This paper includes a brief overview on XACML and discusses its benefits, limitations and a data flow process. We propose a new generic access control architecture that supports enterprise wide centralized application level access control mechanism using XACML. The other benefits which can be achieved through this architecture are, reduce adnministration cost and complexity, support of heterogeneous computing platforms, centralized monitoring system, automatic fail over, scalability and availability, open standard based solution and secure communication.

RFID 기술로 대변되는 표준화된 EPC와 EPCglobal 네트워크를 통한 관련 정보의 흐름은 물류 공급망에서 소비자 요구를 충족시키기 위해 정보를 공유하고 협력하는 방식에 새로운 변화를 일으키고 있다. 효율적인 RFID 기술의 채택을 위해서는 EPCglobal 표준 기반의 통신 및 보안 기술, 그리고 비즈니스 처리를 위한 공통적인 기능이 마련되어야 하고, RFID 환경에 유연하게 대처할 수 있는 표준 아키텍처가 요구된다. 본 논문에서는 효율적이고 안전한 RFID 애플리케이션 개발을 위한 엔터프라이즈 애플리케이션 프레임워크(Enterprise Application Framework : EAF)를 제안한다. EAF는 RFID 엔터프라이즈 시스템을 개발하는데 필수적으로 요구되는 다양한 표준 통신 프로토콜을 이용한 통신 환경, PKI 기반의 보안 기능, 그리고 유연한 RFID 비즈니스 도입을 위한 추상 비즈니스 서비스를 제공한다. EAF를 통해 RFID 비즈니스 통합을 단순화하고, 개발 복잡성이 감소되어 RFID 애플리케이션 개발을 위한 비용 절감의 효과를 가져 올 것이다. 또한 PKI 기반의 보안 기능을 제공함으로서 안전한 RFID 애플리케이션을 개발할 수 있다.

M2M (Machine-to-Machine) Technology makes it possible to network all kinds of terminal devices and their corresponding enterprise applications. Therefore, several M2M platforms were developed in China in order to collect information from terminal devices dispersed all over the local places through 3G wireless network. However, when enterprise applications try to integrate with M2M platforms, they should be maintained and refactored to adapt the heterogeneous features and properties of M2M platforms. Moreover, syntactical and semantic unification for information sharing among applications and devices are still unsolved because of raw data transmission and the usage of distinguished business vocabularies. In this paper, we propose and develop an M2M Middleware to support agile application integration with M2M platform. This middleware imports the event engine and XML-based syntax to handle the syntactical unification, makes use of Ontology-based semantic mapping to solve the semantic unification and adopts WebService and ETL techniques to sustain multi-pattern interactive approach, in order to agilely make applications integrated with the M2M platform. Now, the M2M Middleware has been applied in the China Telecom M2M platform. The operation results show that applications will cost less time and workload when being integrated with M2M platform.

The utilization of the Mobile Government system is having more than a few challenges including complexity of different mobile technologies, determining interoperability among existing systems and infrastructures, and establishing services with secured networks. To get over those challenges, integrated standard, innovative and comprehensive system architecture is required by the M-Government. Hence this study proposed reference EA framework for M-Government system in order to avoid unnecessary duplication of infrastructure deployment and integrate services among different government instructions. The study based on literature review, and current infrastructure and mobile network situation for delivering Government services of Mongolia. The study recommends innovative m-Government system framework used EA, and scope covered mobile service delivery area centered on G4C and C2G perspectives. The Federal Enterprise Architecture Framework has used in this research, and the proposed system service architecture defines the interoperable standards, infrastructure components, applications, and technologies for government institutions in Mongolia to aid interactions necessity among them to provide m-Service.

This paper addresses the issue of workflow on Grid and P2P, and proposes a layered workflow architecture and its related workflow models that are used for not only distributing workflows' information onto Grid or P2P resources but also scheduling the enactment of workflows. Especially, the most critical rationale of this paper is on the fact that the nature of Grid computing environment is fitted very well into building a platform for the maximally parallel and very large scale workflows that are frequently found in very large scale enterprises. The layered architecture proposed in this paper, which we call Enterprise Workflow Grid Architecture, is targeting on maximizing the usability of computing facilities in the enterprise as well as the scalability of its underlined workflow management system in coping with massively parallel and very large scale workflow applications.

To build a successful information system, design and development should be carried out from the enterprise perspective. A complicated business is represented in various ways as technology advances, and many development methodologies have been studied from the viewpoint of technology and development. Each domain is independently designed and developed from the enterprise perspective, but there would be inclusive parts due to the integrated process wherein the definition, design, and development of business are carried out, and the design is done based on the designer's experience. This study would like to address the technique of designing screens based on the business process of the applications derived from the business. It designs the screens that appear when actual applications are completed, including how the data transfer process in the derived business process is represented and operated on the relevant screens. It designs the screen which is displayed when the actual application is completed and how the data transfer process in the derived business process is represented and operated on the relevant screen. In addition, it designs the DFD representing the overall flow of data for each business to represent the movement procedure between screens in general. Through the design method proposed in this study, the client's requirement could be confirmed to reduce the cost for redevelopment, the problem of communication between designers and developers with various experiences could be reduced, and an efficient design procedure could be provided to persons who lack design experience.
