A data service supporting variable input and output parameters
Zhang Fen · Computer Engineering and Science · 2013
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.
