A computer implemented method for locating isolation points in an application under multi-tenant environment includes scanning, using a computer device an application by using scanning rules, to obtain potential isolation points and relationships between the potential isolation points; specifying at least one isolation point among the potential isolation points; and screening an isolation point from the potential isolation points by using relationships between the specified at least one isolation point and the remaining potential isolation points.

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.

A method and apparatus for applying database partitioning in a multi-tenancy scenario is disclosed, the method includes providing, in each database table of a partitioned database system storing tenant data, a partition key field for storing a respective partition key for each tenant within a plurality of tenants. The respective partition key for each tenant is designated for each tenant according to a partition designated for the each respective tenant and the corresponding relationships between partitions and partition keys in the database partitioning mechanism of the partitioned database system. The respective partition key is used by the partitioned database system to perform database partitioning operations on the data of each respective tenant.

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.
