This study aims to show why we have to introduce SOA paradigm in the Cadastral Information System for coping with domestic and foreign IT environments flexibly and strengthening inner capability. We search the trend of up-to-date IT paradigm such as Enterprise GIS, SOA and etc. from this, we worked out the concept of Cadastral Information System. we also could see the introduction case of the domestic and foreign next generation Cadastral Information System, there is implications for us. also, we analysis the general condition about information system which KCSC(Korea Cadastral Survey Corporation) own in a general way and estimate the SOA level degree for each information system. and on that base, we set up SOA loadmap for implementation the next generation of Cadastral Information Service. This is an important step for building ideal future information systems which KCSC hope to be. For realizing this, we focus our inner capability on integration without duplicate and re-using the inner information infra.

Recently, a combination of Business Process Management (BPM) and Service Oriented Architecture (SOA) is being recommended as the best approach for automating large business systems. And the need to create meaningful information from daily operational data is increased today. In this paper, we propose a methodology for automating business processes based on the BPM-SOA convergence trend and verify the methodology by implementing the project management business process. BPM-SOA convergence provides higher extensibility and productivity due to the loosely coupled system construction and maintenance. The system has good properties for frequent process changes and reuse of duplicate processes. We then analyze extensibility of the system as new business processes are added to the existing system. We finally analyze the data generated by BPM by using SAP business intelligence to support management's decision making and strategy. Business intelligence provides not only useful data for business decisions but also chance to optimize the business processes.

Service-Oriented Architecture (SOA) is a development paradigm for reusing services as an independent reuse unit. A service delivers a cohesive functionality through its external interface. Since services have unique characteristics which are not typically presented in conventional development approaches, there is a demand for effective approaches to developing services. Most of the current SOA methodologies presenta process where services are designed and developed from the requirements rather than reusing existing assets, which demands high cost and effort. Hence, a desirable approach is to be able to develop services by migrating from their existing legacy systems such as object-oriented system. A difficulty in this migration is that objects in object-oriented systems reveal characteristics which differ considerably from those of services. That is, objects are designed without considering commonalities among several consumers. In this paper, we first define mapping relationships between key artifacts in object-oriented system and those in SOA services. By these relationships and considering commonalities among several applications in a domain, we propose three systematic methods to migrate from object-oriented system to SOA services. Each method consists of a list of input and output artifacts and detailed guidelines which are performed in order. Through these methods, service developers can easily develop services with less effort.

To survive in rapidly changing business environment, the enterprises of all over the world are trying to integrate their IT infra structure and are trying to automate their business process. Service Oriented Architecture (SOA) is being accepted as an IT standard to support efficient system integration and flexible business process automation between enterprises or departments. The material control system is required this software architecture between manufacturing company and materials supply vendors. This paper introduces concept of SOA, relevant technology about SOA such as Web Services and Business Process Execution Language (BPEL) and Enterprise Service Bus (ESB) and describes how to automate materials control process by designing the material control system based on SOA. The analysis of requirements is proceeded by Unified Modeling Language (UML) and SOA delivery strategy is selected the top-down strategy. And this paper describes how to derive services and operations and how to arrange services in three service layers and how to design business process.

In this paper, SOA Current and Temperature Driver which consisted of LabVIEW programming part capable of current and temperature transient response pattern design, DAQ module for analog voltage in&out, and voltage to current converting chips has realized. The output current(possible to 3A) from the Driver to SOA was clearly constant without ripple and also showed no variance until 1mA unit for a long time operation. The temperature of TEC took several seconds to reach a set temperature, and were maintained stably within ${\pm}^0.1{\circ}C$ for several hours. The proposed Driver can replace the previous high cost SOA Drivers for wavelength swept lasers fully and provides the convenience of transient response design capability for current and temperature.

SOA는 특정 기술이나 플랫폼에 종속되지 않고 느슨한 결합(Loosely Coupled)을 가지고 상호 연동할 수 있는 서비스들의 조합으로 어플리케이션 개발을 가능하게 하는 정보시스템 아키텍처이다. 즉, 한덩어리의 방대한 코드로 이루어진 어플리케이션들을 각각 개발하는 대신 각각의 비즈니스 기능을 수행하는 서비스를 구성하고, 이 서비스를 조합하거나 분리함으로써 비즈니스 프로세스들을 구현할 수 있게 하는 정보시스템 구축을 목표로 한다. 본 연구에서는 SOA기반 소프트웨어의 분야의 기반 기술을 조사하고 SOA기반 소프트웨어 시장과 표준화 동향을 조사하며 SOA기반 소프트웨어 기능성의 품질평가 메트릭을 개발하였다.

기업의 비즈니스 시스템은 수시로 변화하는 고객의 요구사항과 새로운 기반기술의 출현 등에 따라 끊임없이 변화하고 있다. 따라서 기업은 비즈니스 환경변화에 유연하고 신속하게 대응할 수 있는 환경을 필요로 하고 있다. SOA는 이러한 요구에 적합하도록 설계된 아키텍처이다. SOA(Service Oriented Architecture)는 비즈니스를 세분화하여 반복 가능하고 가치를 지닌 단위 서비스들로 나누어 조립과 통합을 통해 새로운 가치를 만들어 낼 수 있도록 지원한다. 하지만 비즈니스 시스템의 많은 부분을 차지하던 Legacy 시스템에 이러한 아키텍처를 적용하기에는 많은 어려움을 가지고 있다. 본 논문에서는 Legacy 시스템으로부터 SOA의 서비스를 추출하는 방법을 제안한다. 서비스를 추출하는 과정은 3가지 단계를 거친다. 첫 번째 단계는 COBOL로 제작된 Legacy 시스템의 프로그램에서 DATA DIVISION으로부터 변수를 분류 및 그룹화하고 PROCEDURE DIVISION의 루틴간의 연관관계를 파악하여 객체화시킨다. 두 번째 단계에서는 첫 번째 단계에서 얻어진 변수들 중 핵심 변수를 식별하여 객체화를 통해 식별된 로직에서 서비스가 될수 있는 로직을 식별한다. 마지막으로 세 번째 과정은 식별된 서비스와 데이터를 사용하여 SOA 서비스를 구축한다.

To survive in rapidly changing business environment, the enterprise should adapt its business process to the changing environment. The system integration is an important issue to tackle this challenge. It is unavoidable direction that SOA (Service Oriented Architecture) is accepted as an upcoming IT standard to support flexible business processes and integration. In this paper, SOA is introduced, and the Web services and ESB (Enterprise Service Bus) ate also introduced as a foundation technology to implement SOA-enabled solutions. The pilot project, which is introduced in this paper, will be a good reference for future SOA implementation.

Web Services 기술의 발전과 더불어 Service-Oriented Architecture(SOA)에 기반을 둔 많은 프로젝트들이 발생하고 있다. 그러나 실질적으로는 SOA에 대한 개념의 부족으로 인하여 효율적인 프로젝트 관리가 이루어지고 있지 못하고 있다. 특히 SOA 개념을 EAI 프로젝트에 적용하는 경우에는 많은 연관된 작업들이 있음에도 불구하고 체계적인 프로젝트 절차가 마련되어 있지 못한 실정이다. 이에 본 논문에서는 산업계 전반에 많이 소개되고 있는 Project Management Institute에서 제안한 PMI 모델을 기반으로 SOA 프로젝트 착수 및 계획 단계의 특징 및 차이점을 살펴보고, 국내 현실에 맞는 착수 및 계획 단계의 산출물을 정의하고 이를 기반으로 착수 및 계획 단계의 관리 모형을 제시하고자 한다.
