How to calculate the likely size of an OLAP cube

由 冷暖自知 提交于 2019-12-10 17:09:26
问题 Does anyone know a method to use to get a rough size of an OLAP cube based on a star schema data warehouse. Something based on the number of dimensions, the number of records in the dimension tables and the number of fact records and finally the number of aggregations or distinct records etc.. The database I am looking at has a fact table of over 20 billion rows and a few dimension tables of 20 million, 70 million and 1.3 billion rows. Thanks Nicholas 回答1: I can see some roadblocks to

Hadoop connectivity with SAS

由 烂漫一生 提交于 2019-12-08 01:20:31
问题 I want to use SAS/ACESS 9.3M2 Interface for connecting sas with my Hive. My question is, whether sas imports hive cubes into sas environment and queries there? or, It again hits hive for the purpose of reporting so that it runs MR which degrades my reporting performance to more than 2-4 secs. If it imports hive tables to its environment what would be its performance when compared to normal sql cubes? I am totally new to sas i want my reports generated with in 2-4 secs where my aggregated data

SSAS cube with multiple DB

由 让人想犯罪 __ 提交于 2019-12-07 00:37:41
问题 I have 3 databases with the same structure, but different data, since they are from different clients. Now, I have an existing SSAS project. Its Data Source Views, Cubes and Dimensions can only use or access one DB. What I want is to be able to use multiple databases with the same structure, and create a cube using them. Each client must also be able to use the cube, but they can only see their own data. Are these possible? Can you please provide insights and some useful references? 回答1: Easy

Calculated measure/dimension

由 你。 提交于 2019-12-06 12:02:40
I'm relatively new to MDX and am trying to accomplish what I think should be an easy thing, but I haven't found any solution. I have a sales cube and one of the measure is profit which can be negative or positive. I want to get one measure which is effectively the sum of positive profit, i.e. only include in the new measure those profit numbers that have a positive profit. The trick here is this is on the row detail level and something like WITH MEMBER Measures.PositivePNL as IIF (Measures.PNL > 0, Measures.PNL,0) doesn't work as that only works with the aggregate number I should have

I would like to just build the cube and query it without having to make use of the Oracle Analytic Workspace Manager. I would appreciate if somone could let me know if I
