PWA立方体步骤概述？ [英] Overview of PWA cube steps?

问题描述

我正在尝试测试我对PWA多维数据集步骤的理解。我现在的疏忽可能是非常错误的。如果这些都是在某处写的，或者如果有示例代码，请指出我并接受我的谢意。

向后工作：

在我看来，立方体处理步骤的主要输入（即完成CubeProcessed事件的步骤）是由前一步骤创建的空（未处理）SSAS数据库，即多维数据集建立步骤。多维数据集
处理步骤的主要输出是完全处理的SSAS数据库，其中包含来自报告数据库的数据。我是否正确？

在我看来，多维数据集构建步骤的主要输入（即事件前的事件是CubeBuilding，其后事件是CubeBuilt的步骤）是当最终用户"保存"时保持的立方体元数据集。 PWA中的多维数据集定义。这个
元数据可以通过CubeAdmin类的各种类（可能是数据集等）访问（OnCubeBuilding）吗？多维数据集构建步骤的主要输出是空（未处理）SSAS数据库。我是否正确？

同样，我并非声称我知道这些事情是正确的，但我要说明这些事情是为了让其他人纠正我不正确的理解。

解决方案

我确实找到了"BuildStage"。
枚举，这似乎映射到我推测的内容：

Init

PreBuildEvent

StructDetermine
BuildOlapCube

PostBuildEvent

ProcessOlapCube

PostProcessEvent

完成

PreBuildEvent =" CubeBuilding"

PostBuildEvent =" CubeBuilt"

PostProcessEvent =" CubeProcessed"

I am trying to test my understanding of the PWA cube steps. My undersanding right now may be quite faulty. If this is all written out somewhere or if there is sample code please point me there and accept my thanks.

Working backwards:

It seems to me that the major input to the cube processing step (i.e., the step whose completion results in the CubeProcessed event) is an empty (unprocessed) SSAS database created by the preceding step, the cube build step. The major output of the cube processing step is the fully processed SSAS database, populated from data from the reporting database. Am I correct?

And it seems to me that the major input to the cube build step (i.e., the step whose pre-event is CubeBuilding and whose post-event is CubeBuilt) is the set of cube metadata that is persisted when the end-user "saves" the cube definition in the PWA. This metadata would be accessible (OnCubeBuilding) via various classes, perhaps the datasets, etc., of the CubeAdmin class? The major output of the cube build step would be the empty (unprocessed) SSAS database. Am I correct?

Again, I am not claiming that I know that these things are true but am stating them in order that others may correct my incorrect understandings.

解决方案

I did find the "BuildStage" enumeration, which seems to map to what I speculated:

Init
PreBuildEvent
StructDetermine
BuildOlapCube
PostBuildEvent
ProcessOlapCube
PostProcessEvent
Done

PreBuildEvent = "CubeBuilding"

PostBuildEvent = "CubeBuilt"

PostProcessEvent = "CubeProcessed"
