Problems solved by technology

[0004] The second method is the slowly changing dimension, which adds an effective start time and end time to the data. When the data changes, a data zipper is added for storage. The data does not change, does not add or update the data, however, using SQL (Structured Query Language , Structured Query Language) to generate zipper development is more cumbersome

Embodiment Construction

[0054] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0055]It can be understood that the terms "first", "second" and the like used in this application may be used to describe various elements herein, but these elements are not limited by these terms. These terms are only used to distinguish one element from another element. For example, a first client could be termed a second client, and, similarly, a second client could be termed a first client, without departing from the scope of the present application. Both the first client and the second client are clients, but they are not the same client. The term "or / and" describes...

Abstract

The invention relates to a data storage method and device, computer equipment and a storage medium. The method comprises the steps of generating a date data item relationship list of each service identifier according to historical data, wherein the date data item relationship list records a corresponding relationship between data dates of data and data item identifiers; generating a data item content list of each service identifier according to the historical data, wherein the data item content list records a corresponding relationship between the data item identifier and the data content; andgenerating a data limit storage table, wherein the data limit storage table comprises each service identifier, and a date data item relationship list and a data item content list corresponding to each service identifier. The development difficulty can be reduced while storage resources are reduced.

Description

technical field [0001] The present application relates to the technical field of data warehouses, in particular to a data storage method, device, computer equipment and storage medium. Background technique [0002] A data warehouse is a subject-oriented, integrated, relatively stable data collection that reflects historical changes. In the data warehouse, there are some business data changes that account for a small proportion of the overall volume (such as members, organizations, employees, etc.), and each use in the data analysis process requires a full traversal of the current date or the full data status of the specified date. Usually, the data warehouse The methods used are periodic snapshot tables or slow-changing dimension solutions, but these two methods have the following disadvantages: [0003] The first method is a periodic snapshot table, which stores a copy of the current full amount of data every cycle; the implementation is simple, and the small amount of dat...
