基于要素类的多数据中心数据一体化存储模型研究 The Study on the Multiple Data Centers Data Integrated Storage Model Based on a Feature Class

本文根据多个一体化数据存储模型，结合多数据中心、分布式异构环境等实际需求，提出了基于要素类的多数据中心数据一体化存储模型，并以国家自然资源和地理信息基础信息库项目为基础，进行了建模。建模结果显示：该模型可以满足多数据中心、分布式异构环境下的海量多源数据一体化存储与管理。 According to the multiple integrated data storage model, this paper proposed the integration of a multiple data center data storage model based on a feature class, combined with the actual needs of multiple data centers and distributed heterogeneous environment. It also built the model based on the project of the National Natural Resources and Geospatial Basic Information Database. Modeling results showed that the model could meet the demands of integrated storage and management of massive multi-source data under the multiple data centers and distributed heterogeneous storage environments.
