  2. In the process of building the multidimensional data model, we made some mends on the time dimension, adapted the time model based on competition, and this model provided enough information for the later analysis based on time. and contempary, this paper used a new schema called star cluster schema as the basic structure of the multidimensional data model. the cluster schema is the joint of star schema and snowflake schema, it inherits their merits, and mends their disadvantages

    在具體的建模過程中，對時間維作了一定的修正，提出了一種基於競爭機制的時間維模型，為基於時間的分析提供了更加充分的信息；同時本文也對常用的多維數據模型的結構作了改進，採用了一種稱作為星族模式的結構，這種結構結合了星型模式和雪片模式的優點，同時又對各自的缺點進行了修正，並在實際中得到了很好的應用。

    本文設計並實現了基於關系的三層olap工具，其中包括基於星型模式的多維建模，多維分析的實現以及多樣的數據發布。
  4. The multidimensional data model of the sample database is designed as star schema. the etl tool is implemented curtly and the tool is independence on structure in order to make the multidimensional query analysis be independent of data source, thereby, the expansibility of system is enhanced

    以星型模式設計了實例數據庫的多維數據模型，並簡單地實現了數據的提取與轉換工具，該工具獨立於查詢分析系統，使得查詢分析與數據來源無關，增強了系統的可擴展性。
  5. The cube model can be seen as an abstraction of a star - join or snowflake - join schema

    多維數據集模型可以看作星形聯結或雪花形聯結模式的抽象。
  6. Use of a star or snowflake schema to organize the data within the database

    使用星型架構或雪花架構來組織數據庫內的數據。
  7. Provides a conceptual overview of cubes in analysis services, and an example of a cube that uses a star schema

    提供對analysis services中多維數據集的概念性概述，並提供使用星型架構的多維數據集示例。
  8. For example, if you are loading data into a star schema, you can build a separate package to populate each dimension and the fact table

    例如，如果將數據加載到星型架構中，則可以生成一個單獨的包來填充每個維度和事實數據表。
  9. Many - to - many dimension relationships expand the dimensional model beyond the classic star schema, and support complex analytics even when dimensions are not directly related to a fact table. for more information, see

    多對多維度關系擴展了維度模型，使其超越了傳統的星型架構，並且即使在維度沒有直接與事實數據表相關時也可以支持復雜的分析。
  10. When you define a dimension based on a star schema, which is where all dimension attributes are derived from the same relational table, an attribute relationship is automatically defined between the key attribute and each non - key attribute of the dimension

    當您基於星型架構（在該架構中，所有維度屬性都派生自同一關系表）定義維度時，會在維度的鍵屬性與每個非鍵屬性之間自動定義屬性關系。
  11. The service consumer creates an inventory request document according to the star schema

    服務消費者根據star模式創建目錄請求文檔。
  12. The data mart. in the argumentation of this part, i introduce the star schema of financial theme land especially

    在這部分的論述中，我重點介紹了財務主題域的星型模型建立過程。
  13. For example, you might create five data flows, each copying data from a flat file into a different dimension table in a data warehouse star schema

    例如，可以創建五個數據流，每個數據流都將數據從平面文件復制到數據倉庫星形架構中的不同維度表中。
  14. For example, if a foreach loop container repeats a control flow that updates dimensions and fact tables in a star schema, you can configure a transaction to ensure that all fact tables are updated successfully, or none are updated

    例如，如果foreach循環容器重復了星形架構中的維度表和事實數據表的更新控制流，則可以配置事務以確保成功更新所有事實數據表，或者不更新任何事實數據表。
  15. At present, the data warehouse systems is more built on the relation database, so the star schema simulates the expression and memory of multidimensional data model by the relation model, for improving visit efficiency

    星型模型是數據倉庫的數據模型設計一個補充部分，目前數據倉庫系統多建在關系數據庫之上，所以星型模型是由關系模型模擬多維數據模型的表示和存儲，提高了數據倉庫訪問效率。
  16. When you define a db2 warehouse target table, you can specify whether the table is created by the db2 data warehouse center, and whether it is a part of an olap schema, which means it might eventually be used as a dimension or fact table in a multidimensional data model, such as a star model

    中可以看到的，在定義db2倉庫目標表時，可以指定是否由db2 data warehouse center創建該表，以及該表是否是olap模式中的一部分，這意味著它可能最終被用作多諸如星型模型之類的維數據模型中的一個維度或事實表。
  17. For the inquiring convenience, comprehensive service and the following data digging, all the tables of system are grouping, and re - edited into “ star schema ” or “ snowflake schema ”. hibernate is an object - relation mapping software which is more and more popular

    在本系統中為了方便查詢，給用戶提供更全面的服務以及下一步要開展數據挖掘等工作，將所有數據表分組，重新設計表結構實現了「雪花型」或「星型」多維數據模型。
  18. An example of a schema participating in a star join query could be a sales table, the fact table containing millions of rows, a product table, containing the description of several hundred products, and a store table containing several dozen store names
