In this paper, we propose a social-based collaboration systems for business process management in the mobile cloud. This XMDR-DAI is to provide services for data sharing and exchange between local systems that operate independently in a cloud environment, take charge of a social-based collaborative business process management. Social-based collaborative business processes are handled in a collision among a structure such as unit conversion, meaning conflict, and the schema mapping data resulting from the inner query. The conflict was resolved by mapping process which takes in each XMDR-DAI.

Ubiquitous Sensor Network (USN) environments, sensors and sensor nodes, and coming from heterogeneous sensor networks consist of one another, the characteristics of each component are also very diverse. Thus the sensor and the sensor nodes to interoperability between metadata for a single definition, management is very important. For this, the standard language for modeling sensor SensorML (Sensor Model Language) has. In this paper, sensor devices, sensor nodes and sensor networks for information technology in the application stage XMDR-DAI -based metadata to define the USN. The proposed XMDR-DAI USN based store and retrieve metadata for a method for effectively agent technology. Metadata of the proposed sensor is based SensorML USN environment by maintaining interoperability 50-200 USN middleware or a metadata management system for managing metadata in applications can be utilized directly.

The large scale of data and operating systems in the trading environment in the cloud. However, technology is not an easy trading system of cloud-based data interoperability. Partially meets the data transfer rate and also the timeliness of the best trading system on the difficulties. Thus various techniques have been introduced for improving the throughput and low latency minimization problem. But the reality is, and the limits of speed improvements like Socket Direct Protocol, Offload Engine with TCP/IP is the hardware, the introduction effect is also low. In this paper, the proposed trading of the cloud XMDR-DAI based stock system. The proposed Safe Proper Time Method for optimal transmission speed and reliability.

Enterprises saved and controled data using individual and various database which were occurred on business. The saved data that were existed in the database were approached by business processing for specified achievement of service's aims and were occurred frequently data migration. This research propose the data migration method using XMDR-DAI(eXtended Meta-Data Registry-Data and Integration) that were occurred by approaching and integration in the process of business processing based on sql query.

In the enterprises the data integration based on service requires integrated data management as the change in the environment of enterprises accelerates. Cooperation among enterprises is accomplished through accessing distributed database using business process. As this approach is performed based on the global query, problems such as data heterogeneity, schema heterogeneity, and verification of validity have to be solved in advance for the interoperability among the heterogeneous system. Thus, cooperation requires dynamic and reliable construction. In this paper, we propose XMDR-DSM (eXtended MetaData Registry-Data Service Mediator) system for cooperation. XMDR-DSM, which is comprised of XMDR-DS, XMDR-DQP, and XMDR-DAI, supports the mapping between global schema and local schema and provides data access and integration service. Therefore, XMDR-DSM enables the mutual support of business operations among heterogeneous database. In addition, it can secure information as reusable asset and the standardization of interchange. Also it can manage unified information since it provides business process based on workflow; therefore, it will be able to increase the life span of information and reduce the cost.

기업이 관리하고 있는 중요한 정보자원들은 대부분이 여러 레거시 시스템에 분산 저장되어 있다. 그리고 저장되어 있는 정보 자원들 또한 서로 호환되지 않는 다양한 형태로 존재하고 있다. 이러한 문제를 해결하기 위해 분산된 데이터의 통합과 지식 공유를 위한 시스템이 필요하다. 데이터 통합의 목적은 기업의 조직과 주요 업무, 핵심 어플리케이션으로부터 발생하는 데이터 소스들의 표준 규칙과 메타 데이터를 이용하여 중복성을 제거하고, 오직 단일 데이터를 제공하는데 있다. 본 논문에서는 XMDR 기반의 OGSA-DAI를 이용하여 통합 검색 시스템을 설계 및 구현하였고, 분산되어 있는 레거시 시스템간의 데이터 통합검색이 가능한 시스템을 제안한다. 제안한 시스템은 분산된 레거시 데이터베이스간의 협업 환경 구성에 적합하며, 실시간 기업환경에서 빠른 정보 전달과 업무 지원 환경에 적절한 시스템이다.

최근 기업은 저장된 데이터를 비즈니스 인텔리전스 기반으로 통합하고 분석한다. 이를 위해서 기업들은 ETL(Extraction, Transformation, Loading) 기술을 이용하여 다양한 소스로부터 데이터를 추출하여 변환한 후 데이터웨어하우스에 저장한다. 그러나 데이터웨어하우스/데이터 마트 기반 비즈니스 인텔리전스 프로젝트들은 기존의 사용하던 툴이 기능상의 한계를 드러내면서 시스템 통합, 마이그레이션, 동기화 등의 어려움이 있다. 특히, 서로 다른 ETL 툴을 사용하는 경우 메타데이터의 통합, 데이터 실시간 동기화 기술, 데이터 표준화, 데이터 매칭 등이 어려워 부분적으로만 지원되고 있는 실정이다. 본 논문에서는 다양한 데이터 통합 및 추출, 변환하여 데이터웨어하우스에 저장할 수 있는 XMDR-DAI를 제안한다.

In cloud environment, business intelligence data warehouse is used for decision making and enterprise policy. But if new system is added in cloud environment, much cost and time is needed due to heterogenous characteristics in data integration. This paper suggests a data cleaning system for business intelligence in cloud environment. The proposed system minimizes the effect of local system when it integrates distributed system using XMDR-DAI. And this system provides standardized information to generate information of data warehouse in real time. Also the proposed system saves cost and time by integrating the data without a change of existed system. And it can improve quality of information by generating coherent information through data extraction and cleaning work in real time.
