Modeling method for cross-domain information sharing exchange data model

Abstract

The invention discloses a modeling method for a cross-domain information sharing exchange data model. The method comprises the following steps: S1, modeling a sharing exchange data dictionary; S2, establishing an information exchange service model; S3, generating a shared exchange directory. The data description is unique to form standardized data dictionaries, the machine readability of the datain the exchange process is realized; the data management problem can be effectively solved; a computer can automatically draw a data association graph to realize unified modeling of shared and exchanged government affair data, a standard shared and exchanged data dictionary is formed, a shared and exchanged directory is optimized according to the dictionary, and the problems of inconsistent data description, single directory structure and the like in a current urban cross-domain data sharing and exchanging process are solved.

Description

technical field [0001] The invention relates to the field of data model modeling, in particular to a method for cross-domain information sharing and exchanging data model modeling. Background technique [0002] At present, all parts of our country are vigorously promoting the construction of new smart cities. The construction of smart cities requires extensive use of various heterogeneous data generated during the operation of cities such as e-government, transportation, public security, medical care, industry and commerce, and finance to improve urban comprehensiveness. The modernization level of governance enhances citizens' sense of security, gain and happiness. Information sharing and exchange is a key component to realize the convergence and integration of urban big data, and it is also an inevitable requirement to realize data circulation and maximize the value of data scale in the era of big data. In particular, the refinement of social division of labor has increase...
