【摘要】 Web Services技术作为新一代分布式计算技术,能够为异构数据资源的集成提供强有力的支持。由于科技资源数据库学科特点及资源单位的自治性,资源描述格式不统一、信息交换和共享不畅。针对该现状,提出基于Web Services的异构数据资源透明访问方案,给出系统体系框架及实现中的关键技术。通过Web Services注册机制将各数据资源单位提供的数据和建设方法进行注册,为用户提供一个统一透明的访问接口。更多还原

【Abstract】 Web Services is a new distributed computing technology,which can provide strong support to the integration of heterogeneous data resource.Because of the discipline characteristics and the resources organization autonomy in the scientific resource database,resources description form is not unified,and the exchange and sharing of information is impeded.In view of the current situation,this paper brings forward a program for heterogeneous data resource transparent access based on Web Services.It provides heterogeneous data resource transparent access framework and the important technologies of the realizing process.The data resource organizations can register their data and constructive methods through Web Services registration mechanism,and provide a unified transparent access connection for the user.更多还原
