    • An information processor may include a command receiving unit that receives an immediate processing command in which a deletion target to be deleted from the database is conditioned, and a registration processing unit that registers information defining the deletion target into a management data unit. In addition, the information processor may include a deletion processing unit that deletes the deletion target from a database, and deregisters the deleted deletion target from the management data unit. The information processor can also include a data manipulation command processing unit, which, in the case where a data manipulation command having a manipulation target that coincides with a table of the deletion target registered in the management data unit is received, processes the data manipulation command in a state where a condition to exclude the deletion target from the manipulation target is added to the data manipulation command.
    • 信息处理器可以包括命令接收单元,其接收其中要从数据库中删除的删除目标被调节的立即处理命令;以及注册处理单元,其将定义删除目标的信息登记到管理数据单元中。 此外,信息处理器可以包括删除处理单元,其从数据库中删除删除目标,并且从管理数据单元注销已删除的删除目标。 信息处理器还可以包括数据操作命令处理单元,在接收到具有与登记在管理数据单元中的删除目标的表一致的操作对象的数据操作命令的情况下,处理数据操作命令 在从操作对象排除删除对象的条件被附加到数据操作命令的状态下。

    • An apparatus is provided with base table storage sections that store base tables and delta tables for the base tables, a summary table storage section that stores a summary table for storing results of queries to a plurality of base tables and delta information about the summary table, delta data processing sections that insert delta data of the base tables into the delta tables, and a delta computation processing section that generates delta information about the summary table. The delta computation processing section is provided with a generation section that generates delta information about a specified base table on the basis of an update that has been performed for the base table, in a situation where a subsequent update of the specified base table is permitted; and a control section that performs control so that, when a different base table is specified, delta information is generated in a different transaction.
    • 提供了一种设备,用于存储用于基表的基表和增量表的基表存储部分,汇总表存储部分,其将用于存储查询结果的汇总表存储到多个基表和关于汇总表的增量信息, 增量数据处理部分,其将基本表的增量数据插入增量表;以及增量计算处理部分,其生成关于汇总表的增量信息。 增量计算处理部分具有生成部,其在允许指定的基表的后续更新的情况下,基于对基表进行的更新,生成关于指定的基表的增量信息; 以及控制部,其执行控制,使得当指定不同的基表时,在不同的事务中生成增量信息。
