This paper is to show the meaningfulness of applying Information Technology Architecture (ITA) to the modeling of a nation-wide e-Business architecture framework. After reviewing various architecture frameworks we suggested a unique architecture framework called VMT (Views, Models, and Time-frames). VMT represents five views of e-Business stakeholders; six models of data, function, network, agent, event, and rule; and three timeframes of short-term, mid-term, and long-term. VMT is an extension and unification of popular frameworks including Zachman's framework that has international recognition and use, C4ISR architecture framework of US DoD's, and Federal Enterprise Architecture Framework (FEAF) of the US Federal Government's.

오늘날 국내 금융시장은 정택 및 규제에 대한 변화와 구조조정 및 인수 합병을 통한 금융회사의 대형화와 금융상품간의 복합 및 연계된 종합금융서비스를 제공하는 등의 급격한 환경 변화를 겪고 있다. 이러한 환경변화 속에서 금융 시스템 운영의 주체가 되는 마스터 데이터가 각각의 시스템에 개별적으로 관리되고 있어 이로 인해 금융 데이터의 품질 관리에 어려움이 생기게 되고 데이터의 중복 및 일관성에 문제가 생기게 되었다. 본 논문에서는 자크만 프레임워크를 활용한 통합 마스터 데이터 관리시스템을 제안한다. 이러한 마스터 데이터 관리를 통해 데이터 중복 및 데이터 정합성 보장, 시스템 연계간의 유연성을 확보하는 기대 효과를 예상할 수 있다.

Until now there have been many kinds of enterprise architecture frameworks including the DoDAF in defense domain, the FEAF in administration domain, and the TEAF in finance domain. These EAFs define EA viewpoints for supporting each domain and propose perspectives and models for each viewpoint. These EAFs provide consistent models from different perspectives that interact with each other. However, they have too many perspectives so that their complexities are too high, or they do not define enough models for concrete architecture description. Especially, they neither consider business values, that mean the ultimate purpose of an organization nor execute processes for achieving the business values. This paper thus proposes the VBEAF, business value based enterprise architecture framework that considers and executes business values in organizational business processes.

Architecture framework (AF) is a guideline to define components needed to develop and operate enterprise architecture (EA), and to define relationships among the components. There are many architecture frameworks to operate EA of governments and businesses such as Zachman framework, DoDAF, TOGAF, FEAF, and TEAF. DoDAF is the most representative AF to support the development of the EA in the military domain. DoDAF is composed of eight viewpoints and 40 views that are affiliated with the viewpoints. To develop an AF for a specific goal, system architects decide a set of views. Furthermore, they determine data that are needed for a view modeling. However, views and data in DoDAF are structurally inter-related explicitly and/or implicitly. So, developing an AF for a specific goal is going to be a project to be carried out over a long haul. To reduce the burden of its development, in this paper, we develop ONT-SAF (Ontology for DoDAF) that can infer inter-relationships like referential and transitive relationships and the sequences among the views. Furthermore, to promote reusability and consistency of the views and the data within an AF, we adopt the view-data separation strategy. ONT-DAT contains classes like 'viewpoint', 'view', 'data', 'expression method', and 'reference model', and 11 properties including 'hasView.' To prove the effectiveness of ONT-SAF, we perform a case study.

Reference modeling for Collaborative Networked Organizations(CNOs) has just started, and Enterprise Architecture Modeling Languages(EAMLs) for CNOs are very few. Lack of reference models makes it difficult for people to communicate with each other and lack of EAMLs also makes it difficult to implement information systems for CNOs. We propose an EAML for CNO called CAML. It supports (1) multi-level modeling based on Model- Driven Architecture of OMG's for expressive power and efficiency of implementations, and (2) multi-focus modeling based on Zachman Framework for completeness of modeling The effectiveness of the CAML is investigated through modeling of a supply chain and execution of change impact analysis.
