A data modeling and processing method

Abstract

The invention discloses a material data modeling processing method. The method includes: designating meta-material types of material and specifying inherent metadata items of the material; specifying extended metadata items of the material, and defining features of the extended metadata items; defining material type contents, and building a material type model according to the meta-material types, the extended metadata items of the material, spatial features of the material and business rules of the material type; generating a data type model according to structure features of a solid file of the material; correlating the material type model to the data type model by matching names of data types and material names of the material types, building an initial material data model, and storing the model in a database. The inherent metadata items and the extended metadata items are used as field sources for material type modeling. According to the method, the material types and the corresponding data types are classified and modeled by modeling, and data processing is more reasonable, more direct, faster and clearer.

Description

technical field [0001] The invention relates to the field of information processing, in particular to a method for modeling and processing data-type data. Background technique [0002] At present, surveying and mapping data management departments need to manage and maintain a variety of surveying and mapping data, such as documents, disks, CDs and other media data or digitized electronic data. These data cover different sources, different types, and different time and space. Information is complex in terms of data classification, physical form, storage status, and data format, and the data volume is large. From the point of view of surveying and mapping data management methods, most surveying and mapping data management departments are still in the traditional manual bookkeeping or electronic file bookkeeping, and only a few departments have begun to use database storage and management, but for massive and complex data For database storage, it is difficult to quickly and co...

[0002] At present, surveying and mapping data management departments need to manage and maintain a variety of surveying and mapping data, such as documents, disks, CDs and other media data or digitized electronic data. These data cover different sources, different types, and different time and space. Information is complex in terms of data classification, physical form, storage status, and data format, and the data volume is large

From the point of view of surveying and mapping data management methods, most surveying and mapping data management departments are still in the traditional manual bookkeeping or electronic file bookkeeping, and only a few departments have begun to use database storage and management, but for massive and complex data In terms of database storage, it is difficult to quickly and completely build a library body with a single data structure

[0003] At present, the common data management software still builds databases for surveying and mapping data according to the data content itself, lacking model support, and the development workload is heavy, and the attributes and spatial information of surveying and mapping data are stored separately, which is not good in application display effect. very good
