I've generated some mining models against an OLAP data source (dimension). However, when I go to generate a lift chart, it seems that the only data source that can be used for input is the data source view (the relational database). Is that right? Or is there something I'm missing here.
I was figuring I'd use one slice to train the model, then another slice to test the accuracy of the results. But right now it's looking like I can't do that.
I am starting using OLAP service. The first problem the first day I use it.
I setup a system DSN for OLAP under ODBC source. I use SQL driver to create a data source to a SQL server. I am using SQL SA login account. Then I go into OLAP manager create database. Then in the library I set up a data source using the DSN I created before.In the General Tab I use OLE DB for ODBC provider. After this I try to create a new cube using the wizard. I got error the message that the SQL login is invalid. I double check it is right login account. I failed several times. Then I tried directly create data source under library and not using the DSN I created before. The first time it failed again has the same message. Then the second time when I create data source I use NT authentication instead SQL login. Now everything went fine. I was able to create a cube. But I still wondering what is preventing using SQL login account when creating data source.
Thanks for the help
I prepared an OLAP cube for the report data source in the SSAS 2005. The OLAP cube consists of more than 20 dimensions and several measure groups. I then created the subset/view of the OLAP cube using the "Prepective" function and limit to not more than 7 dimensions on each of the subset. How do I reference the OLAP cube subset as the data source when developing the report in the report designer. Furthermore what is the advantage of creating multiple smaller OLAP cubes with less dimensions comparing to one big OLAP cube with several subset/view attached to it. Thanks.

I tried to create a lift chart with my custom plugin-algorithmn. The chart seems to be correct, but before it is drawn, an error occours:
Function ... Row 1 ... Column 43 ... cannot be used in this context.
(I've translated the key facts of this error message from german)
What did I do wrong?

Hi,
I am having trouble really understanding what makes a model accurate and effective at predicting some attribute. I can't seem to find any clear documentation about the mining legend of the lift chart on the Mining Accuracy Chart tab when working with the Data Mining Structure designer in VS 2005. Specifically, I would like to know more about what numbers in the Score, Population Correct and Predict Probability columns mean, and why they change when you move the vertical gray bar on the Lift Chart. Also, what is generally a good score to be aiming for, provided that it is highly difficult to get 100% accuracy with the kind of data that I am using.
Any more information on this subject is much appreciated. Thank you for your time,
Chris Burns
Hello Readers,
I would like to use an OLAP Connection Manager in a script task.
I have found this link: http://msdn2.microsoft.com/en-us/library/ms136060.aspx, where a SQLConnection is used:
Dim connMgr As IDTSConnectionManager90
Dim sqlConn As SqlConnection
Dim sqlReader As SqlDataReader
Public Overrides Sub AcquireConnections(ByVal Transaction As Object)
connMgr = Me.Connections.MyADONETConnection
sqlConn = CType(connMgr.AcquireConnection(Nothing), SqlConnection)
End Sub
Does anyone know, which coding has to be used to be able to use AcquireConnection for an OLAP Connection manager?
Thanks in advice!
Cheers,

Hello . Because of my graduation project , I interested in data mining application , Adventureworks DW on MS VS 2005 . I opened File->Open->project/solution ->Enterprise -> AdventureworksDW .then I successfully deployed the algorithms decision tree and Clustering . Then I opened tab Mining Accuracy Chart then selected input table "testing" , which I had created before , from vTargetMail . After that , mining structure table and target mail table has automaticaly linked each other .Next , I selected predictive input as 1 , of the predictable row "BikeBuyer" . But , when I clicked "Lift Chart ", I only got a 45 degree line , everytime .. How can I fix it ?

I think I found a bug or something, I have created a package like this
For Loop Container
OLE DB source, Sql Variable the query is an openquery with an MDX query
Script Component (just ToString("+00,-00") transformations)
OLE DB destination
End loop
the MDX query is changed within the variable which is evaluated as expression.
when I run that package the process msmdsrv.exe starts consuming more and more memory.
I don't know if it's the analysis services cache that gets bigger or something else. but if it is, how do I clear it in SSIS?
just in case, the mdx query goes like this:
select {[Datos Resumen Mensual]}
on columns,
[Cuenta].[Cuenta].&[variable1]:[Cuenta].[Cuenta].&[variable2] on rows
from [Bd Rtd]
WHERE ([Tiempo].[Mes].&[2007-09-01T00:00:00],[Unidad Negocio].[Unidad Negocio].&[1])

Hi,
I have just run a simple data set through a model to predict a simple true or false value (i.e. binary output)
The Lift Chart/Mining Legend in Analysis Services shows three results €“ Score, Population Correct (%), and Predict Probability (%)
Population Correct I beleive is the percentage of predictions it got right out of the total number of predictions it tried to make. Is this correct?
However, I can€™t work out how the other two are derived in particular the 'SCORE'. To give a live example the scores were as follows:
Model Score Pop Correct Pred Probability
Decision Trees 0.83 76.59% 54.28%
Neural Network 0.75 67.63% 50.05%
Ideal Model 100.00%
Can anyone help with this and give a detailed explanation?
Many thanks,

Thanks a lot for your answer
Please don€™t move this question because I don€™t know where I should write this.
I have set up a new connection as a connection from data source, but I cannot see how to use this connection to create my Data Flow Source. I have tried using an OLE DB connection, but this is painfully slow! The process of loading 10,000 rows takes 14 - 15 minutes. The same process in Access using SQL on a linked table via DSN takes 45 seconds.
Have I missed something in my set up of the OLE DB source / connection? Will a DSN source be faster?
Thanks in advance

On the subject of Data Warehouses, Data Cubes & OLAP….I would like to speak frankly about Data Warehouses, Data Cubes andOLAP (on-line analytical processing). Has it dawned on anyone elsethat these buzz words were created by some geek who decided to take astab at marketing? Knowing that to the backwoods manager who knowslittle of technology that new innovative names for old concepts wouldhelp to sale their products.I mean seriously, what is the story here? In a nut shell, and pleasestop me if you disagree, but isn’t a data warehouse simply adatabase? Can’t you do everything on a conventional databaselike SQL Server, Oracle or DB2 that you can do on these newproprietary Data Warehouse constructs? I mean who are they trying tofool?Take a look, for instance, at Data Cubes. Who hasn’t noticedthe striking similarity between data cubes and views used in all themore robust databases? Also, what about OLAP? OLAP is nothing morethan a report generator. There’s nothing you can do with thesemillion dollar price tagged Data Warehouse total solution packagesthat I can’t do with SQL Server, Oracle or DB2…for thatmatter Microsoft Access.As an example some sales people for Metadata Corporation has the VicePresident of I.T. in Nashville, for Healthspring, sold on their totalsolution data respository which is such a scam. All they had to dowas throw a couple of buzzwords at him and they have him hypnotized.Personally, I feel that these kinds of marketing practices undermineour industry. It helps to unravel what little standards orconsistency we have. What do you guys think?Stuart

Today I was making a few reports.
When I tested the reports in Visual Studio, they worked great: I got the expected result.
But when I deployed the reports to our reportserver the problem started.
When I click on the directory in which my reports are deployed, I got my 4 reports.
Till now everything worked correct.
But when I click on a report to view the results it went wrong.
I got an error:
"Cannot create a connection to data source 'Live'"
(Live is the name of our data source).
We are using the Windows Logons and I am sure that I have all the rights on the server, I gave myself 'sysadmin' rights, so it should work.
I also have tried it with all the roles assigned on my account, but then it still won't work.
When I modify the data source, and set it to another server en database it works.
The datasource 'Live' exists on a x64 MsSQL server, en the other datasource is on a x86 MsSQL server.
Maybe that is the problem?
Can someone tell me what is wrong?

Hello,If I wrote the next ebay (yes I know, yawn-snore) and I had a databasewith 5 million auction items in it, what would be a really goodstrategy to get a search done very quickly? Would it involvesomething called OLAP and/or "data mining"? The only technology I amfamiliar with is simply SQL Server databases with stored procedures.I think I'd be guessing correctly and say that this technology simplywouldn't be fast enough *on it's own* to do super fast queries againstmassive amounts of data.Any insights would be of great interest. Thanks.-Frameworker.
View 5 Replies View RelatedI was trying to load data using SSIS, Data Flow Task, OLE DB Source, source was a view to a OLE DB Destination (SQL Server). This view returns 420,591 rows from Query Analyzer in 21 seconds. Row length is 925. When I try to executed the Data Flow Task from SSIS, I had to stop the process after 30 minutes, because only 2,000 rows had been retrieved. I modified the view to retun top 440, 000 and reran. This time all 420, 591 rows were retrieved and written in 22 seconds. Next, I tried to use a TOP 100 Percent. Again, only 2,000 rows were return after 30 minutes. TempDB is on a separate SAN Raid group with 200 gig free, Databases on a separate drive with 200 gig free. Server has 13 gig of memory and no other processes were executing.
The only way I could populate the table was by using an Execute SQL Task and hard code an Insert into table selecting data from the view (35 seconds) from SSIS.
Have anyone else experience this or a similar issue? Anyone have a solutionexplanation?
Is any way to export and import an olap cube whithout his data?

I have an OLAP server and would like to use my Chart FX software without having to purchase the OLAP extensions on the server due to budget restraints (ouch).
I've heard that it is possible (although limited) to attach toan OLAP cube using SQL select statements (not MDX).
Basically, I would like to pull the OLAP data in the relational sense.
Is this possible? If so, are any good articles on this subject?
I'm new to OLAP and would like to transition slowly.
Thanks in advance :)
Hi:
The drillthrough in my cube is working fine except for the cases where the dimension member is null. For example I have the dimension
PRODUCT (dim)
- PROD_TYPE_CD (name = PROD_TYPE_CD || '-' || PROD_TYPE_NM)
- PROD_CD
-PROD_NM
So for if the data is like the following where the PROD_TYPE_CD is null :
- (name = -FOOD)
- 123
- bread
The drillthough is not displaying any data no matter I select the PROD_TYPE_CD, PROD_CD or PROD_NM in the dimension drop down altough if query the DB directly I found data to display in the drillthrough
Any ideas why this is happening and how to solve it.
Thanks

After reading some threads on this forum about accessing OLAP data from SSIS via an OLE DB Source component (and trying it myself and getting that "pcrsstore.cpp line 325" error), I have worked around the problem by using a Script Task component.
This calls a .NET assembly I wrote that uses ADOMD.NET to get at the data using an MDX query, and then actually posts an event to a Notification Services instance via a stored proc.
Writing, deploying, and maintaining a .NET assembly is more than I wanted to do, but it was worth the effort since now I know a little about extending SSIS when I need to.
But what I really wanted to do was the following, all from within the core components of SSIS:
Import my OLTP data into my relational warehouse (already done using SSIS)
Process the cube (already done using SSIS)
Access the cube via MDX and post an event to Notification Services
It's this last step that needed some special work because of SSIS's apparent limitation accessing cube data (although posting the event to NS would be easy because SSIS can call a stored proc on the NS application database).
So I'm hoping that a future release or service pack of SSIS will give us some components to run MDX and get the OLAP data into the pipeline as if it were from any other source.
Thanks for reading, and if anyone has any suggestions on a better way to achieve what I need please let me know!

I am using data flow task.And data flow source uses ole db for olap 9.0 to connect my ssas. sql comment is my access mode. A mdx query extracts data. Data flow destination is sql server table. Error said Data Flow Task: OLE DB Source [579]: The output "OLE DB Source Output" (589) references an external data type that cannot be mapped to a Data Flow task data type. I guess it is a implicit data type convertion problem. But how to solve it???
I appreciate for all suggestion. Thanks.
I'm working with PivotTable on Excel 2000 which is connected to an OLAP server (from SQL Server 7 installation). The pivot is intended to analyze Sales during April 2001. Yesterday I found out that OLAP/Excel returned/displayed inconsistent data. The 'April Total' value is NOT equal to the 'Quarter 2 Total' (I already inspected the underlying database and sure that there is absolutely NO data for months after April 2001). The value for 'April Total' is the correct one. I'm not sure whether the problem resides on the OLAP Server or Excel (pivot) itself. For ones who like to help me I would be glad to supply you with the screenshots (just email me).
Please help.
