When I process a cube in Visual Studio 2005 I get following message: Process succeeded. Trace information is still being transferred. If you do not want to wait for all of the information to arrive press Stop. and no trace info is displayed. Cube is processed OK by it is a little bit annoying. Any ideas? I access cubes via we...

I am about to migrate a bunch of seriously over-complex Reports (MS SQL report server over some horrible stored procedures) to something more BI based. I was wondering if anybody had any pointers, gotchas, or general advice on the best way to do this. Thanks. ...
Are there any excellent sources (book, podcast, tribal folklore, etc) fo rgetting a grasp on using OLAP for data analysis in SQL Server (or just in generic terms that can be applied to SQL Server)? ...
I have a multi dimensional OLAP cube with a number of dimensions. Some of these dimensions have hierarchies. The users would like to perform 'what-if' analysis on the measures in the cube by changing the hierarchies in the dimensions. For example, they want to know the impact on departmental resource budgets by moving employees between...
We have a client that has Oracle Standard, and a project that would be ten times easier addressed using OLAP. However, Oracle only supports OLAP in the Enterprise version. Migration to enterprise is not possible I'm thinking of doing some manual simulation of OLAP, creating relational tables to simulate the technology. Do you know of ...
Is there a simpler interface for end users to run "queries" on pre-existing SqlServer Analysis Service cubes? I'm looking for a way to deploy the cubes and allow the users to work with the data through a simpler interface than BIDS. Is this even possible? ...
I need a real DBA's opinion. Postgres 8.3 takes 200 ms to execute this query on my Macbook Pro while Java and Python perform the same calculation in under 20 ms (350,000 rows): SELECT count(id), avg(a), avg(b), avg(c), avg(d) FROM tuples; Is this normal behaviour when using a SQL database? The schema (the table holds responses to a s...
I have a pivot table on an olap cube. I can go into a page field and manually deselect multiple items. How can I do this in VBA based on a list of items I need excluded? (n.b. I do not have a corrresponding list of items I need included) I know how to exclude these items in other ways, by altering the underlying query for example. I spe...
I have an MDX query which lists a measure for all 'Week' and 'Day' levels in the OLAP database. For example SELECT { HIERARCHIZE( {[Business Time].[Week].members, [Business Time].[Date].members} ) } ON ROWS, { [Measures].[Quantity] } ON COLUMNS FROM [Sales] Where the measure is displayed for a Week though, instead of showi...
I am trying to build an OLAP datasource from a bunch of binary files, and our current model just isn't working. We are using SSAS as our analysis / reporting model for our results, but aren't able to get the performance we want out of SQL. Our main constraints are: The database is very large. We have huge dimension tables with mil...
When I'm in Windows, I use the excellent MicroOLAP Database Designer for PostgreSQL, but its not open source or multiplataform. Do you know or can recommend me an alternative to this software, that I can use in Linux? EDIT: Just to clarify, I don't want to use wine to emulate MicroOlap for PostgreSQL, it doesn't work too well, I would p...
What is a good free/open source alternative to WebFOCUS? Is there an ASP.NET way of getting info from an OLAP cube? Update: I chose Magnus Smith's answer as the correct one, but Alexmac's answer was also very good! ...
I'm building a data warehouse that includes delivery information for restaurants. The data is stored in SQL Server 2005 and is then put into a SQL Server Analysis Services 2005 cube. The Deliveries information consists of the following tables: FactDeliveres BranchKey DeliveryDateKey ProductKey InvoiceNumber (DD: degenerate dimension)...
Hi, I need to define a calculated member in MDX (this is SAS OLAP, but I'd appreciate answers from people who work with different OLAP implementations anyway). The new measure's value should be calculated from an existing measure by applying an additional filter condition. I suppose it will be clearer with an example: Existing measur...

Unfortunately, when I went to codeplex page I found that page supposed to deliver an ascmd doesn't work. Please help if you know any other page, where I can download ascmd or any other program execut...
I'm planning software that's an OLAP application at its heart (it helps analyse metering data) and is going to have some kind of star schema for its database, because the stored values will be looked at from different angles (time, source, type etc.) and the requests will be asking for aggregated data along these dimensions. The queries ...
Hello, I'm trying to see data in my OLAP cube by ascmd utility. As input I put a MDX query, but only what I have as output (in command line) is a XML file. I tried to use -Tf text and -Tf csv parameters, but they don't work in the way I think they should (I have a XML on output all the time). I want to have on my output something like...
