    • The present invention provides a flexible, dynamic database partition method and system. The method includes the steps of acquiring a data partition rule, where the data partition rule is used to identify a first relationship between a data partition condition and a database partition; establishing a second relationship between the data partition condition and a data partition key based on the data partition rule and a third relationship between the database partition and the data partition key; adding the data partition key to a data item where the data item is stored in the database based on the second relationship between the data partition condition and the data partition key; and storing the data item in the database partition based on the data partition key of the data item.
    • 本发明提供了一种灵活的动态数据库分区方法和系统。 该方法包括以下步骤:获取数据分区规则,其中使用数据分区规则来识别数据分区条件和数据库分区之间的第一关系; 根据数据分区规则和数据库分区与数据分区密钥之间的第三关系建立数据分区条件与数据分区密钥之间的第二关系; 基于数据分区条件和数据分区密钥之间的第二关系将数据分区密钥添加到数据项存储在数据库中的数据项; 并且基于数据项的数据分区密钥将数据项存储在数据库分区中。

    • 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.
    • 一种用于在多租户应用系统中处理物化表的方法,系统和计算机程序,其中在所述多租户应用系统中,多个租户共享一个或多个基本表。 根据多个租户的数据访问历史信息,更新模式分析器分析多个租户对一个或多个基本表的更新模式的相似性。 此外,根据由更新模式分析器分析的相似度,租户分组装置将多个租户分组成多个租户组。 另外,根据由租户分组装置分组的租户组,物化表构造器从一个或多个基本表构建租户组物化表。
