Most enterprise information systems today are silo systems in that they are not properly aligned nor integrated with one another. Such silo systems result because enterprises lack an architectural perspective in the planning and development of the systems. This paper proposes an Enterprise Architecture Orientation Model as a framework for the analysis, planning and design of the architectural quality of enterprise information systems. The model decomposes enterprise architecture into two dimensions-alignment and integration, and specifies for each dimension the general development and evolution stages enterprises may traverse. The alignment dimension represents the vertical strategic alignment of the systems with the vision, mission, strategy and goals of the enterprise, and is analyzed in terms of the performance, capability, and strategy of the enterprise. The integration dimension, on the other hand, represents the horizontal and functional integration among the systems that span organizational functions and boundaries, and is analyzed in terms of such technological components as IT infrastructure, data, application, and business processes. The model combines the alignment and integration dimensions to form a two-dimensional conceptual space for mapping the architectural quality of the enterprise. It is proposed that an enterprise use the model to identify and understand its position now and in the future in the architectural quality of the enterprise information systems. It is also proposed that the model provides a tool for the planning and design of the transition from one stage to the next in the alignment and integration of the systems to reach an architectural maturity. At the end, the paper discusses how the model can be applied differently according to the strategic orientation of the enterprise. An example of the usage of the model is presented.

Nowadays most enterprise want to organize all Information Technology elements for their vision and mission accomplishments by integration view Enterprise architecture is used by the solution. But IT is so more complex that it can't cover application development. This research defines software architecture framework by enterprise view and designs enterprise architecture framework for embracing application development. Software architecture framework consists of meta architecture, conceptual architecture, logical architecture, physical architecture. For enterprise architecture framework including enterprise software architecture framework, this research analyzes its perspectives and Views. After all, This research able to apply to systematic application development based on enterprise architecture and completely IT elements organization by enterprise view.

This paper proposes an image prediction system architecture for deep running in enterprise environment. Easily transform into an artificial intelligence platform for an enterprise environment, and allow sufficient deep-running services to be developed and modified even in Java-centric architectures to improve the shortcomings of Java-centric enterprise development because artificial intelligence platforms are concentrated in the pipeline. In addition, based on the proposed environment, we propose a more accurate prediction system in the deep running architecture environment that has been previously learned through image forecasting experiments. Experiments show 95.23% accuracy in the image example provided for deep running to be performed, and the proposed model shows 96.54% accuracy compared to other similar models.

본 연구에서는 엔터프라이즈 아키텍처(Enterprise Architecture:EA)의 운영 및 성과에 영향을 미치는 요인으로 EA의 핵심성공요인과 EA 전담조직의 역할을 선정하였으며, 특히 EA 전담조직의 중요성을 증명하고자 한다. 구체적으로 EA 관리 및 운영단계에서의 핵심성공요인을 기반적, 문화적, 제도적의 세 요인으로 분류하였고, EA 전담조직의 역할은 계획관리, 체계관리, 인적자원관리, 정보관리, 위험관리의 다섯 가지 분류로 나누어 각각의 요인이 EA 성과에 어떠한 영향을 미치는지 알아보고자 한다.

Recently, as both business processes and IT systems become ever more complex. Especially, enterprise applications tend to become unmanageably complex and increasingly costly to maintain. Therefore complexity is the insidious enemy of software development. It is critical to have a methodology that recognizes and manages this enemy effectively. In this paper, we propose ISIS (Integrated System of Independent Subsystems) - the architectural style needed to develop the complex enterprise applications. The ISIS was developed to meet the challenge of reducing the complexity of a larger enterprise application today. It gives us architecture models for reducing development complexity and composite application. The enterprise application is partitioned into a collection of independent subsystems using ISIS decomposition schemes and equivalence relations. We use middleware named ISIS engine that provides a service for subsystems interoperability by enabling the integration of distributed, cross-platform subsystems. We have implemented an ITSM system that achieves our objectives, reducing development complexity, using the ISIS architecture. Finally, ISIS architecture provides greater flexibility and productivity when an organization needs either to change its business processes, or to update the underlying systems.

Data is the kernel of IT. We can apply to other architectures are refer to technology and advanced method. Data architecture is our's native that must be implement ourself. It will suggest to the best method to implement for a sound information system that likes to framework of building because data is not sensitive field of evolution and change of technology. Well implemented data architecture can be effectively management and operation. Also this is easily to implement of enterprise architecture. This paper propose a model of implementation data architecture for enterprise architecture.

Spatial information is essential for administrative affairs. So many Administrative Information System(AIS)s and Geographic Information System(GIS)s have been implemented at local government to support administrative affairs. AIS deals with document based information, and is not designed to use map information. Also, various information is not matched, because address systems for AIS and coordinate system for GIS are different. Therefore, existing AIS and GIS are not suitable for linking administrative affairs and spatial information. This paper deals with the enterprise architecture for local government to support the linkage of administrative affairs and spatial information. Enterprise architecture in this paper is composed of business architecture, data architecture, application architecture, and technical architecture. Each architecture is designed up to planner's and owner's level. Detail structures of each architecture follow the practical guidance for applying e-government enterprise architecture in Korea. Business and data architecture are applied to transportation administrative affairs.

기업들은 정보기술 리스크(IT Risk)에 대하여 어떻게 대처하고 있을까? 금융기관이나 공공기관은 태생적으로 이미 위험관리를 적극적으로 수행하고 있다. 정보기술에 대한 위험관리도 지난 10년동안 전산망 마비, 해킹 사고, 디도스 공격, 고객정보 유출 등을 겪으면서 적극적으로 대응해 왔다. 특히 2011년 농협사태는 IT 성과보다는 IT 보안을 훨씬 중요하게 보는 계기가 되었다. IT 보안 인력과 예산이 대폭 강화되고 망분리 사업이 추진되는 것이 대표적인 사례이다. 하지만 그동안 IT 위험관리는 특정 기술에 대한 사전 대응 및 사후 대응 강화에 집중되었다. 현재 IT 위험관리는 단편적 관리에서 종합적 관리로 전환되고 있다. 최근에 많은 기업들이 전사 차원의 정보기술 리스크 거버넌스(IT Risk Governance) 체계를 구축하고 있거나 구축하는 계획을 갖고 있다. 하지만 아직도 IT보안은 전사적으로 통합되지 못하였으며, IT 위험관리 프로세스는 조직에 내재화 되지 못 하였고, IT 성과관리와 연계성은 고려하지 못하고 있다. 본 논문에서는 IT 관리와 기술을 효과적으로 연계하기 위하여, 그리고 IT 성과와 IT 위험을 균형되게 관리하기 위하여 엔터프라이즈아키텍처(EA: Enterprise Architecture) 활용을 제안하고자 한다.

지금까지 개발된 대다수의 정보시스템은 시스템 품질 요소인 상호운용성, 이식성, 확장성 및 재사용성 등이 극히 미흡하여 통합성이 부족할 뿐 아니라 과도한 유지보수비를 요구하고 있다. 더구나 이러한 시스템의 컴포넌트들은 엔터프라이즈 범위에서 개발되지 않아서 해당 시스템 외에서는 재사용을 할 수 없다. 정보기술아키텍처 및 엔터프라이즈아키텍처는 이러한 문제를 해결하기 위하여 출현하였다. 본 논문은 엔터프라이즈아키텍팅 개념을 기반으로 시스템 컴포넌트의 품질을 향상 할 수 있는 방법을 제시하는 것으로, 먼저 아키텍팅개념을 발전시킨 엔터프라이즈아키텍팅에 대하여 살펴보았다. 둘째, 시스템 컴포넌트의 품질 요소를 정의하기 위하여 시스템기반 상호 운용성, 이식성, 확장성, 및 TCO개념을 시스템 컴포넌트개념으로 재정의 하였으며, 셋째, 이를 기반으로 시스템 컴포넌트의 품질 요소인 재사용성을 정의하였고, 마지막으로, 엔터프라이즈아키텍팅에 의해 시스템 컴포넌트의 재사용성이 향상됨을 보여주었다.
