【摘要】 传统Web服务提供一组包含固定输入、输出参数的操作,通常无法满足针对数据资源的内容提出的各种查询请求。提出一种支持可变输入、输出参数的数据服务,其操作可以满足基于数据内容的各种查询请求。首先,服务描述中添加数据内容的描述,指明服务能够提供哪些数据;然后,定义了一个支持可变输入、输出参数的操作,其输入是一个包含输入、输出参数及参数约束的查询请求,输出是查询请求中输出参数所对应的数据;最后,给出了关系型数据的服务化方法,并通过实验从功能角度验证了方法的有效性。更多还原

【Abstract】 Traditional Web services provide operations with fixed input and output parameters,thus they cannot meet various queries based on the content of data resources.A data service supporting variable input and output parameters is proposed,and various queries based on the content of the data can be met.Firstly,description of the contents of data supplied by the service is inserted into the service description,and data provided by the service can be determined by the description.Secondly,the operation supporting variable input and output parameters is defined.The input of this operation is a query containing input parameters,output parameters and constraints,and the output of this operation is the data corresponding to output parameters in the query.Finally,the method for servitization of relational data resources is given,and the effectiveness of the method is validated through experiments.更多还原
