Embodiment Construction

[0057]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0058] see figure 1 , this embodiment discloses a method for creating a data model, which specifically includes the following steps:

[0059] S101: Acquiring the information of each data item in each preset field respectively;

[0060] Specifically, the preset domain is a business domain pre-divided according to data sources, such as personnel organization, finance, materials, projects, power grids, assets, and customers.

[0061] Specifically, the data item ...

Abstract

This application discloses a method and device for creating a data model, which obtains the information of each data item in each preset field respectively; establishes the mapping between each data item in each preset field and the entity class in the preset standard model relationship, creating a data sub-model for each preset domain according to the mapping relationship in each preset domain and the information of each data item; respectively determining whether each data item in each preset domain is a cross-domain data item, And according to the cross-domain data items, the data sub-models of each preset domain are integrated to obtain the target data model. Solve the fragmentation problem of the existing data model and avoid the "information island" phenomenon in the process of informatization construction.

Description

technical field [0001] The present invention relates to the technical field of data processing, and more specifically, to a method and device for creating a data model. Background technique [0002] In previous data warehouse BI projects, the methodology and concepts of the data model usually revolved around how to design and build the data warehouse, while the model design of the application system (OLTP system) lacked the guidance of the methodology. Self-designed and developed in different periods, lack of communication with each other, resulting in scattered and repeated data, inconsistent caliber and poor data compatibility. Since the data warehouse belongs to the downstream system in the overall information planning of the enterprise, it can only passively receive the data generated by various application systems. After the data is stored, it will bring great difficulties to data integration due to inconsistent caliber and poor compatibility. Enterprises are investing...
