Hi All ,
I have some query about the dimension options in Kylin.
We have three options.
Normal , Derived and Hierarchial.
The Kylin GUI says that " A derived dimensions will be auto generated for
lookup tables" what is meaning of this ?
About hierarchial dimension suppose I have a dimension table as;
Areaid , areaname , province , city
So in fact table I can just store the area id as foreign key and make the
hiererchy dimension area with areaname->province->city and I can drilldown
the data from area to province and city ?
Is it possible for some one to explain these with a simple example , I
have tried to read couple of presentations of kylin but things are not very
clear to me.
Regards,
