specific example 1

[0070] Taking a distributed database for project management as an example, the business data is centered on the project data table, and each business data table has a direct or multi-table cascaded relationship with the project data table. The business data of the central database and the site database The table structure is the same, and the process of distributing all business data of a project from the central database to the site database is as follows: image 3 As shown, the specific steps are as follows.

[0071] 1) Obtain the basic structure information of the central database. The basic structure information of the database includes information such as database type, table structure, column information of the table, primary key and foreign key of the table.

[0072] 2) According to the basic structural information of the central database, the business data table association relationship is established. The most important content in the association relationship of dat...

Abstract

The invention provides a step-by-step database data distribution uploading and synchronizing method. A step-by-step database system consists of a center database and a plurality of station databases. The step-by-step database data synchronizing method comprises the following steps: data distribution processing and data uploading processing, wherein in the step of the data distribution processing, business data are exported from the center database and imported into the station databases; and in the step of the data uploading processing, the business data are exported from the station databases and imported into the center database.

Description

technical field [0001] The invention relates to a step-by-step database data distribution uploading synchronization method. Background technique [0002] With the increasing scale and regionalization of information systems, the role of data bridges played by distributed databases in information systems is becoming more and more important, and the design of distributed databases is widely used in systems. However, due to the system's own characteristics and different requirements for the system, there are still many problems to be studied and solved in the process of designing a distributed database system. One of the most important issues is how to ensure the data synchronization of the distributed database to ensure the consistency and security of the entire system data. [0003] In distributed database systems, data replication technology is widely used for data replication and transmission, so as to achieve the purpose of data synchronization. Almost all large-scale dat...
