Problems solved by technology

[0005] However, none of the visual data warehouse modeling platforms currently on the market can automatically realize such figure 1 The layout method for the star schema shown
In actual development, a fact table is often associated with many dimension tables, which makes the number of dimension tables often exceed 10; therefore, when the number of dimension tables is large, if the layout can only be adjusted manually If not, the efficiency is very low, which greatly affects the development progress and user experience

Abstract

The present invention relates to a method and device for generating a web front-end star model layout, and an electronic device. The specific method includes: sorting the dimension table, dividing the sorted dimension table into a left column and a right column; obtaining The height and width data of the dimension table determine the maximum width as the column width of the column, and determine the column height of the column according to the sum of the heights of each dimension table and the preset vertical interval data; according to the width and height data of the column , the preset vertical interval and horizontal interval data, as well as the width and height data of the fact table, determine the width data and height data of the display area; arrange the fact table in the center of the display area, and generate the dimension table and the left column according to the sorting Dimension table for the right column. The present invention can calculate the position of each table when arranged according to the star model according to the association relationship between the fact table and the dimension table and the fact table and the dimension table, automatically realize the layout of the star model, and improve the development efficiency.

Description

technical field [0001] The present invention relates to the technical field of data visualization, in particular to a method and device for generating a web front-end star model layout, and electronic equipment. Background technique [0002] The fact table is a table that records structured data that describes facts. It is used to record the full amount of information on the content of the analysis, including the specific elements of each event, as well as specific events, such as bank transaction information, order information, etc.; dimension table It is the code table referenced by the fact table, which is the description information of the elements of the event in the fact table, and represents the angle from which the user observes the transaction, such as bank account, order customer, etc. [0003] The star schema is the simplest and most commonly used data model. It consists of a fact table (FactTable) and a set of dimension tables (DimensionTable). The fact table is ...
