Abstract

The invention provides a construction method and construction device for a data warehouse model. The method comprises the steps of constructing a business model by business modeling and conducting abstraction processing on the business model to generate a domain model; dividing the domain model into a plurality of topic models by using multiple topics; determining the mapping relationship betweenentities of each topic model according to the business logic; constructing the data warehouse model according to the mapping relationship between the entities of each topic model. The method divides the domain model into multiple topic models, which is beneficial for fully and effectively achieving data analysis and mining; the mapping relationship between the entities of each topic model is determined according to the business logic, the data warehouse model is constructed, and the stability and scalability of data are effectively improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for constructing a data warehouse model. Background technique [0002] With the development of e-commerce, the data in daily operations has shown explosive growth, and the data structure has also begun to diversify. The data contains more and more information, and more and more attention has been paid to digital operations. Data warehouses are used to sub-process data and play a huge role. [0003] The establishment of a data warehouse model is designed based on the business of the enterprise. The industry-standard data warehouse model has many levels, complex mapping relationships, and cumbersome model changes, which make the industry-standard data warehouse model unable to adapt to different businesses in various industries; due to the rapid development of e-commerce business, the existing data warehouse model cannot quickly Responding to rapid changes i...
