Abstract

The invention discloses a data model creation method and device. The method comprises the following steps of: respectively obtaining each piece of data item information in each preset field; respectively establishing a mapping relationship between each data item in each preset field and entity classes in a preset standard model, and creating a data sub-model in each preset field according to the mapping relationship in each preset field and each piece of data item information; and respectively determining whether each data item in each preset field is a cross-field data item or not, and integrating the data sub-model in each preset field according to the cross-field data items so as to obtain a target data model. According to the method and device, the fragment problem of existing data models is solved, and the phenomenon of Information Island in informational construction process is avoided.

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...
