| 中文摘要 | Data service provides unified data model for cross-domain data integration, and generates data view through data services composition. A challenging problem is once a primitive data service is updated, how to propagate the update bottom-up to the top level via several intermediate composite data services, and to ensure the update efficiency of the data view. In this paper, the data operations and their properties are analyzed to facilitate transformation of composite data services, and generate some equivalent composite data services from a user defined composite data service. In addition, the time cost model for the incremental update of a composite data service is built. The model measures the time cost of updating a composite data service within a time unit in terms of the update frequency and data volume of the primitive data services. Based on the model, a data view update optimization algorithm is proposed to minimize the time cost. Experiments show that our approach can effectively improve the update efficiency of the data view. |
