Abstract

The invention provides a data modeling method and device, a storage medium and an electronic device, and the method comprises the steps of building a target data model in response to a building operation received at a modeling operation interface, the target data model having N attributes, and N being a natural number greater than 1; in response to a first selection operation on M attributes in the target data model, forming a target data table in the target database, the first selection operation being used for indicating that the target data table is generated according to the M data, the target data table comprises M fields, the M fields being in one-to-one correspondence with the M attributes, M being a natural number larger than or equal to 1, and M being smaller than or equal to N; and establishing an association relationship between the target data model and the target data table, the association relationship being used for indicating that the target data table is generated based on the target data model. According to the invention, the problem that the association relationship between the established data table and the data model cannot be determined in related technologiesis solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a data modeling method and device, a storage medium, and an electronic device. Background technique [0002] Data modeling refers to the abstract organization of all kinds of data in the real world, determining the scope of the database to be governed, the organizational form of the data, etc. until it is transformed into a real database. A data model for an information system, as a conceptual data model, is essentially a set of initial specification techniques for documenting data requirements. The data is first used to discuss the initial requirements suitable for the enterprise and then transformed into a logical data model which can be implemented in the conceptual model of the data structure in the database. The realization of a conceptual data model may require multiple logical data models. The final step in data modeling is to determine the logical data model into the ph...
