Problems solved by technology

[0003] There are generally two common solutions: one is that each tenant copies a copy of the original data to the private space, and the data of each tenant is isolated from each other and does not affect each other. However, in the case of a large number of users, a large amount of database storage space is required, resulting in waste , and it is difficult to synchronize data between all tenants when the provider updates the data
The second solution is to use the application to isolate data between tenants, and to associate the updated data with the existing data through the application. On the one hand, the development and maintenance of this solution is very heavy and the scope of application Also affected, on the other hand, due to excessive data interaction between the database and the application affects the overall performance and concurrency

Abstract

The invention relates to data processing, and particularly discloses a method for managing database in a multi-tenant system. The method comprises the following steps of providing public data, wherein the public data is read-only for tenants; providing tenant data, wherein the tenant data is established based on the public data and is private for the tenants; providing a data structure for recording metadata information of the tenant data; responding to the operation of the tenants on the tenant data, recording the metadata information of the tenant data corresponding to the operation in the data structure, wherein the operation at least comprises one of update or delete. According to the method provided by the invention, on the premise that database performance and concurrency are not influenced, less data storage space is utilized for realizing support for multiple tenants.

Description

technical field [0001] The present invention relates to data processing, and more precisely, the present invention relates to a method and device for managing databases in a multi-tenant system. Background technique [0002] In a multi-tenant system, especially a multi-tenant-based software-as-a-service (SaaS) system, the multi-tenant provider will publish or periodically update some public information for all tenants to use. Tenants may modify or delete these data or add new data according to their own conditions to meet their own needs. How to efficiently save and display these data in the database system, and how to process these data is a key issue. [0003] There are generally two common solutions: one is that each tenant copies a copy of the original data to the private space, and the data of each tenant is isolated from each other and does not affect each other. However, in the case of a large number of users, a large amount of database storage space is required, res...
