Recent technology advances in information technology and other engineering fields provide new opportunities for research and practices in precision agriculture. Using these technologies, field operators can collect voluminous data from a heterogeneous network of devices that provides real-time and multiple-factor measurement of field conditions with much finer granularity. A major challenge in precision...
Geographic information is inherent to many application domains in various disciplines and constitutes an integral part of Earth sciences, including geology, geophysics, meteorology, hydrology, oceanography, and soil science. Communication of sophisticated geographical data requires the use of complex technologies that enable interoperable geospatial information exchange channels. The primary authorities...
ASIP is very suitable for the processing core of embedded systems, and the software technology of MDA, UML/XML provides security for its tools, the coupling between them will be the next technology feature. Moreover the design schema for ASIP MDA based UML/XML has been put forwarding in the paper.
Entity Data Model (EDM) is a new conceptual model developed by Microsoft; it is a Platform-Independent and executable conceptual model. At present, EDM is mainly used for information integration, so Microsoft has developed the tools for transforming Platform Specific Models, such as Relational Data Model (RDM), to EDM. On other hand, EDM as a conceptual model can also be used for designing database,...
The Service Data Object (SDO) is one of the most promising data integration frameworks of the enterprise application area. SDO provides us with a unified and mature programming framework for SOA based development to handle heterogeneous data sources. Separation of data accessing from the SDO API is more flexible while makes the characteristics of performance less noticed. Therefore we here study the...
Considering the current situation of the data on oil and gas resources in China, which is relatively multi-sourced, heterogeneous and decentralized, as well as the actual demand of OLAP, MVC model is employed as the system constructing model. Besides, ODBC and XML technology are combined to achieve dynamic mapping on database connection. Thus the National Petroleum Resource Database ETL System which...
The scientific computing manages massive amounts of very large data sets. The development of description of the format, structure and semantic content of data is essential for the automatic manipulation of data. The aim of this paper is to define an XML-based language for describing the structure, semantic and annotation of scientific data. The XML Schema and the Document Type Definitions (DTDs) that...
The technological impact of the Internet gave birth to telemedicine that provides both the digitalization of patient's medical records, and the coordination between different healthcare actors. Work in this domain has shown that the standard XML is one of solid supports for the specification of the structure and of the semantic of clinical information, especially XML also ensures publishing medical...
One of the main open issues in the development of applications for sensor network management is the definition of interoperability mechanisms among the several monitoring systems and heterogeneous data. Interesting researches related to integration techniques have taken place, they are primary based on the adoption of sharing data-mechanisms; furthermore in the last years, the Service-Oriented Architecture...
In this paper, we propose the Service Data Link model (SDL), a service relationship modeling schema, to describe service data correlations, which are data mappings among the input and output attributes of services. SDL recognizes the close correspondence between service data correlations and webpage hyperlinks, and defines service data correlations with explicit declarations, making it more expressive...
This paper discusses the data integration solution for the civil aviation information system which is based on SOA and deals with many kinds of data from various machines and places. Therefore the need of heterogeneous data integration becomes a pretty important concern of the overall design of the system. SDO provides us with a unified and mature programming framework for SOA based development. So...
LDAP is quite popular in the storage of some certain kinds of data, And SDO is about how to integrate data in SOA environment and becomes more and more popular. Accessing to LDAP Using SDO will be quite useful. This paper discusses how to convert the schema from LDAP to SDO, and how to implement the functional model of LDAP using SDO and some other techniques.
Interoperable DEVS modeling and simulation is desirable to enhance model composability and reusability with DEVS models and non-DEVS models in different languages and platforms. The barrier to such interoperability is that DEVS simulators implement the DEVS modeling formalism in diverse programming environments. Although the DEVS formalism specifies the same abstract simulator algorithm, different...
The establishment of IT-supported processes within organizations requires the integration of existing distributed legacy applications. Therefore, Web services can be generated as wrappers to flexibly integrate existing distributed legacy applications using a standardized interface. Existing approaches mostly focus on the technical issues of the integration using Web services and do not support the...

The most important aspect of service oriented architecture is that it uses XML to express processes, rules and conversions. The traditional way of relational modelling of data requires the transforming data into XML when integrating service types accessing to data layer. The basic way to solve the problem of data conversion is to keep the data in its source as XML. This will both reduce conversion...
The Web was an information resource with dynamic state, at the same time, As the spatial data complexity and its multifamily of application field, to get implicit and useful knowledge of space, it is necessary to study the integration issues of the spatial data and choose a suitable technology for data processing and analysis. In the paper, the features of spatial datum were analyzed, they were seriate...
Due to the dynamic nature, such as runtime composition and evaluation, it is critical for an SOA system to integrate its data, which concerns security, reliability, and integrity of data as it is routed in the system. To solve the data integration problem in current business systems, a dynamic data integration model based on SOA is proposed. This model which is dynamic and application oriented extends...
In this paper, we present a formal description of Web services container architecture based on Z notation. This description major focuses on internal behavior of a Web services container on processing a Web services request. First, we present a formal model of tailored XML which provides a unified data structure for executing Web services specifications and data transformation. Then, we present a...
In this paper, the definition of digital distribution networks embodies the spirits and final goals of digital distribution networks. Therefore, the designing of support platform satisfying the definition of digital distribution networks is an important subject in the process of developing digital distribution networks, and the definition's contents are analyzed to achieve the function requirements...
