    • A method of data loading for large information warehouses includes performing checkpointing concurrently with data loading into an information warehouse, the checkpointing ensuring consistency among multiple tables; and recovering from a failure in the data loading using the checkpointing. A method is also disclosed for performing versioning concurrently with data loading into an information warehouse. The versioning method enables processing undo and redo operations of the data loading between a later version and a previous version. Data load failure recovery is performed without starting a data load from the beginning but rather from a latest checkpoint for data loading at an information warehouse level using a checkpoint process characterized by a state transition diagram having a multiplicity of states; and tracking state transitions among the states using a system state table.
    • 大型信息仓库的数据加载方法包括:将数据加载到信息仓库中同时进行检查点检查,确保多个表格之间的一致性; 并使用检查点从数据加载失败中恢复。 还公开了一种与数据加载到信息仓库中同时进行版本控制的方法。 版本控制方法可以处理在更高版本和先前版本之间的数据加载的撤消和重做操作。 执行数据加载失败恢复,而不从一开始就开始数据加载,而是从最新检查点开始,使用特征在于具有多个状态的状态转换图的检查点进程在信息仓库级别进行数据加载。 并使用系统状态表来跟踪状态之间的状态转换。

    • A method for use with an information (or data) warehouse comprises managing the information warehouse with instructions in a declarative language. The instructions specify information warehouse-level tasks to be done without specifying certain details of how the tasks are to be implemented, for example, using databases and text indexers. The details are hidden from the user and include, for example, in an information warehouse having a FACT table that joins two or more dimension tables, details of database level operations when structured data are being handled, including database command line utilities, database drivers, and structured query language (SQL) statements; and details of text-indexing engines when unstructured data are being handled. The information warehouse is managed in a dynamic way in which different tasks—such as data loading tasks and information warehouse construction tasks—may be interleaved (i.e., there is no particular order in which the different tasks must be completed).
    • 一种与信息(或数据)仓库一起使用的方法包括以声明性语言的指令管理信息仓库。 该指令指定要完成的信息仓库级任务,而不指定如何实现任务的某些细节,例如使用数据库和文本索引器。 详细信息是从用户隐藏的,并且包括例如在具有连接两个或多个维度表的FACT表的信息仓库中,当处理结构化数据时的数据库级别操作的细节,包括数据库命令行实用程序,数据库驱动程序, 和结构化查询语言(SQL)语句; 以及正在处理非结构化数据时文本索引引擎的细节。 信息仓库以动态的方式进行管理,其中不同的任务(例如数据加载任务和信息仓库构建任务)可以被交错(即,不存在必须完成不同任务的特定顺序)。

    • Techniques for reducing a number of computations in a data storage process are provided. One or more computational elements are identified in the data storage process. An ordered structure of one or more nodes is generated using the one or more computational elements. Each of the one or more nodes represents one or more computational elements. Further, a weight is assigned to each of the one or more nodes. An ordered structure of one or more reusable nodes is generated by deleting one or more nodes in accordance with the assigned weights. The ordered structure of one or more reusable nodes is utilized to reduce the number of computations in the data storage process. The data storage process converts data from a first format into a second format, and stores the data in the second format on a computer readable medium for data analysis purposes.
    • 提供了用于减少数据存储过程中的多个计算的技术。 在数据存储过程中识别一个或多个计算元件。 使用一个或多个计算元件生成一个或多个节点的有序结构。 一个或多个节点中的每一个表示一个或多个计算元件。 此外,对一个或多个节点中的每一个分配权重。 通过根据分配的权重删除一个或多个节点来生成一个或多个可重用节点的有序结构。 利用一个或多个可重用节点的有序结构来减少数据存储过程中的计算次数。 数据存储过程将数据从第一格式转换成第二格式,并将数据以第二格式存储在计算机可读介质上用于数据分析目的。
