This post from SqlBatman describes a situation similar to my current client and, in reality, indicative of many companies that rely on tons of reports which have been shifted to over-night processing because of their performance impact.

Using Entity Framework with an SSAS Cube

阅读更多关于 Using Entity Framework with an SSAS Cube

问题 Is it possible to use Entity Framework (any version, including, and preferably 4.0) to query an SSAS cube (preferably SSAS 2008)? 回答1: I would say no. There's a few questions on here looking for that, asking for the ORM equivalent for SSAS and such. LINQ to MDX would be lovely, but so far as is known it's just not on the cards. I've been looking and pondering for years for something simple in code to get data back to the middle tier, but I've never found it. Things like AdomdDataReader and

Media queries PX vs EM vs REM

阅读更多关于 Media queries PX vs EM vs REM

Can anyone explain why my media queries break when converting them FROM px TO ems In the body of my document, I have included the following rule font-size: 62.5%, Therefore I would assume that I could convert my media query to FROM 650px to 65em? Changing my media queries to ems breaks the layout As an alternative, can I convert the media query to REMS with a pixel fallback ?? that said, I have no idea how to do this @media screen and (min-width: 650px) { body { font-size: 62%; background-color: #364759; background-repeat: repeat-x; background: url("bg.gif"); } #wrapper, footer { width: 80%;

Logical order an MDX query is processed

阅读更多关于 Logical order an MDX query is processed

What is the order of evaluation of the clauses within an MDX script? WITH MEMBER measures.A AS ... MEMBER measures.B AS ... SET S1 AS ... SELECT { measures.A ,measures.B ,measures.x } ON COLUMNS {S1} HAVING <condition> on ROWS FROM [Cube] WHERE ({S2}) FROM WHERE WITH SELECT HAVING ? But maybe not that simple as a MEMBER and a SET are dealt with differently in terms of context - so if this order is correct how does context tie in? I would say: FROM (including potential subselects) WHERE SETs and MEMBER location in the WITH clause Build the list of tuples for all query axes (columns, rows, ...)

SQL Server 2012: Login failed for user 'NT Service\\MSSQLServerOLAPService'.; 28000

阅读更多关于 SQL Server 2012: Login failed for user 'NT Service\\MSSQLServerOLAPService'.; 28000

I am using Analysis services in Microsoft SQL Server 2012 on Windows 7. I tried to create Mining models and process it. I am getting the following error while processing it. OLE DB error: OLE DB or ODBC error: Login failed for user 'NT Service\MSSQLServerOLAPService'.; 28000. How to correct this and process the model successfully? I recently encountered a similar error. My error was fixed by creating a new login in ssms, with the name the error gave me. In your case it would be 'NT Service\MSSQLServerOLAPService' You then need to check 'db_datareader' and the 'db_datawriter' in that new login

Changing sql-server DB from tabular to multidimensional

阅读更多关于 Changing sql-server DB from tabular to multidimensional

问题 I have following problem: When I try to deploy my SSAS project (with cube, dimensions and all that jazz) to sql-server, it throws error saying that You cannot deploy the model because the DB deployment server is not running in multidimensional mode. I'm new to this, so it might be a dumb question, but how do I change database mode from tabular to multidimensional? 回答1: Tabular and Multi Dimensional are completely different thing. When you install SQL Server, you have to choose which one you

问题 I have the following Import-Module SqlServer $Analysis_Server = New-Object Microsoft.AnalysisServices.Server $Analysis_Server.connect("$server") $estimatedSize = $([math]::Round($($($Analysis_Server.Databases[$cube].EstimatedSize)/1024/1024),2)) this generates for me the size in MB I would like to enhance this to make it more user friendly readable especially for values that are in the double digit MB for example, sometimes i get values 50.9 MB which is good. but some other values are 37091

What is Multi Dimension OLAP CUBE and give example cube with more than 3 dimensions

阅读更多关于 What is Multi Dimension OLAP CUBE and give example cube with more than 3 dimensions

As I am new to SSAS, have been reading an article on Multi-Dimension OLAP Cube and struggling to understand Cube concepts, It has been said that Although the term "cube" suggests three dimensions, a cube can have up to 64 dimensions. Could you please explain how is this possible on cube (other than 3-Dim example x,y,z planes)? Please don't give only links to study but also expecting some explanation. Don't think of a cube as a three-dimensional structure (despite the name). A "dimension" in a data warehouse situation is simply a varying value that you can use to access data in your warehouse.
