问题描述
您好，
我想请求提取Oracle数据到SSAS表格的最佳实践，即：
I would like to ask for Best Practices on Views extracting Oracle Data to SSAS Tabular, namely:
1）如果我应该在视图上进行atttributes转换（并测试空值）。直到现在唯一的问题是一个属性有1,2，空值和日期，而SSAS没有"理解"他们是什么，我已经完成了演员文字。我还做了一些
NVL以避免空... ...
1) if i should do atttributes conversion on the view (and test for nulls). Till now the only problem was one attribute that had 1,2, nulls and dates, and SSAS didn't "understand" what they were, and i've done a cast to text. I have also done some NVL's to avoid null...
2）我正在研究法语系统，因此在属性上有很多重音和大名。出于这个原因，我不得不在数据工具中命名它们，因为我有问题需要处理（SSAS不接受超过30个字符，我认为，所有那些重音符号
都没有帮助.... ）。无论如何要在Oracle上执行此操作吗？
2) I'm working on a French System, so with lots of accents and big names on attributes. For that reason i had to name them inside Data Tools, because i was having problems to process (SSAS doesn't accept more than 30 characters, i think, and all those accents weren't helping either....). Is there anyway to do this on Oracle?
3）我有一个相对较小的窗口要处理，大约15米。如果我在数字1和2中实现我的要求，那么处理时间会增加多少？...
3) i have a relatively small window to process, about 15m. If i implement what i ask in numbers 1 and 2, will the process time increase to much?...
4）任何其他最佳实践在将Oracle数据处理为表格时如何提醒
4) Any other Best Practice how remind off, when processing Oracle data to tabular
谢谢
问候
Regards
推荐答案
我想你可以试着用view来创建表格模型，对于列使用友好名称（WK_NUM将显示为类似"周数"），并且只插入在Tabular中有用的列，这可能会提高模型的性能。您可以将

I think you could try to use view to create tabular model, use friendly name(WK_NUM would appear as something like "Week Number" ) for column and just insert column which is useful in Tabular, this might will improve performance for model. You could refer to Analysis Services Tabular Best Practices – Part 1(part 2 and part 3's link are in the same page) for details.
