摘要： The present invention relates to a multi-tenant technology. The disclosure provides a method for processing a file access request to a multi-tenant application by using a file proxy and a corresponding file proxy apparatus, the method comprising: intercepting a file access request; converting the file access request based on a predetermined file isolation model; and transmitting the converted file access request to an operating system. By using this invention, the necessity of modifying a source code of an application so as to enabling a single-tenant application to support an operation in the multi-tenant model may be reduced. The present invention further provides a multi-tenant file system adapted for a multi-tenant application. In cooperation with the multi-tenant system, the method and file proxy apparatus according to the present invention may provide transparent support to fulfill security isolation and access control of tenant files with different SLAs.
摘要翻译：本发明涉及多租户技术。本公开提供了一种通过使用文件代理和相应的文件代理装置来处理对多租户应用的文件访问请求的方法，所述方法包括：截取文件访问请求; 基于预定文件隔离模型转换文件访问请求; 以及将转换的文件访问请求发送到操作系统。通过使用本发明，可以减少修改应用程序的源代码以使得单租户应用能够支持多租户模型中的操作的必要性。本发明还提供一种适用于多租户应用的多租户文件系统。与多租户系统合作，根据本发明的方法和文件代理设备可以提供透明支持，以实现具有不同SLA的租户文件的安全隔离和访问控制。

摘要： A method, system and computer program for processing materialized tables in a multi-tenant application system, wherein in the multi-tenant application system, a plurality of tenants share one or more basic-tables. According to the data access history information of the plurality of tenants, an update pattern analyzer analyzes the similarity of the update patterns for one or more basic-tables by the plurality of tenants. Furthermore, according to the similarity analyzed by the update pattern analyzer, a tenant grouping means groups the plurality of tenants into a plurality of tenant groups. Additionally, according to the tenant groups grouped by the tenant grouping means, a materialized table constructor constructs the tenant group materialized tables from the one or more basic-tables.
