问题 In the past I used to build WebAnalytics using OLAP cubes running on MySQL. Now an OLAP cube the way I used it is simply a large table (ok, it was stored a bit smarter than that) where each row is basically a measurement or and aggregated set of measurements. Each measurement has a bunch of dimensions (i.e. which pagename, useragent, ip, etc.) and a bunch of values (i.e. how many pageviews, how many visitors, etc.). The queries that you run on a table like this are usually of the form (meta

问题 I recently ran into a problem in our SQL Server 2008 Analysis Services Cube. Imagine you have a simple sales data warehouse with orders and products. Each order can be associated with several products, and each product can be contained in several orders. So the data warehouse consists out of at least 3 tables: One for the Products, one for the Orders and one for the reference table, modelling the n:n relationship between both. The question I want our cube to answer is: How many orders are

问题 I'm new to the MDX/OLAP and I'm wondering if there is any ORM similar like Django ORM for Python that would support OLAP. I'm a Python/Django developer and if there would be something that would have some level of integration with Django I would be much interested in learning more about it. 回答1: Django has some OLAP features that are nearing release.

问题 I searched the Internet and StackOverflow and was not able to find an answer to this issue. I created an OLAP cube via SSAS with a date dimension. One of the attributes of the dimension is Activity Calendar Month . The NameColumn value is formatted like "January 2015", "February 2015", etc. The KeyColumns is set as a DATE value type for the first of the month, for each month. Example, NameColumn value "January 2015" = KeyColumns value "1/1/2015", "February 2015" = "2/1/2015", etc. The

问题 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

问题 I need to create a Calculation in the SQL Server Data Tools. Imagine that in my OLAP structure I have a City and a Seller Dimensions, and a fact. And in the City Dimension I have a city, a state, and a Population, and this is a Measure in a Dimension. I need to sum the Population in the cities which have sales. But I can't sum only the cities with sales, I can only show the state's total population. One seller can sell in many cities. Example: I'll filter by seller John and the query returns

问题 I am working with a SSAS 2008 R2 cube and interrogating the data through Excel 2010. In the cube I have a calculation to conditionally format the data. The logic is if a measure contains a specific value for the fact being viewed, then the fact should be colored red, as follows: CALCULATE; SCOPE ( [Measures].[Data value] ); If([Fact Base].[Confidentiality Status].[Confidential]) Then Fore_Color(This) = 255 End If; END SCOPE; When I have a [Data value] of 0 (zero) the fore_color doesn't render
