Which SSAS Data Mining Task Should I Use?
Jan 24, 2008
Hello:
I would like to send data feeds to Sales Reps listing customers with their likelihood of purchasing a product from a certain Category. The data will basically contain Customer Name, Category, Likelihood Score (or Probability Score). When sorted in Descending order of Probabililty a Sales Rep can easily see the customers who are most likely to purchase at the top of the list and can call them.
I figured I would explore the use of SSAS data mining for this, and integrate it within an SSIS data flow (needed to send the data out to the sales reps).
I have not worked on Data Mining and so am clueless as to where to begin. I have been reading a book on it but most of the examples this far show me how the results can be viewed within AS, which is not what I am looking for.
Ideally I would like to run an algorithm against all our product categories for 2007 and store the results to a table. Then use that table as a lookup to get the probability score for specific categories that we are targeting in 2008.
I appreciate any advice for the experienced SSAS folks on this forum.

Hi all,
I am using SSAS 2005. The mining model works fine. But it crashes when I run the 'Mining Model Predictions' against large data sets.
I ran it against 5,000,000 records and it went fine.
But exactly same model failed for 5,100,000 records and beyound.
The message is 'Query Execution Failed' and then Visual Studio crashes.
Pl. let me know if anybody has the same experience or knows the solution.
Thanks,
Vikas

Hi, all here,
I am wondering where can I store my mining results in data mining engine? For example, I got mining results like accuracy chart, decision trees, and other formats of results based on different mining algorithms I used for my data mining, so where can I actually store the results for reporting service use later? Is it possible to do that in SQL Server 2005?
Thanks a lot for any help and guidance in advance.

Hi!
I have problem using Data mining query task: when I want to set connection to Analysis services DB I don't see connections created in connection manager (they are not listed in the dropdown). (I can click on "New" and create new one but I already have one created in connection manager.)
Also, I want to make connections created in the connection manager flexible, easy to change after transfering package(s) to another server. How to do that?
Thanks in advance!

Hi, I'm new to this forum, so please bare with me.
I've created a mining model, i've tweaked it etc and i'm now happy with the results its producing. I'm now looking to automate the processing and exporting of the results of the model i've done this simply by creating an SSIS package with two tasks, one task being to process the model the other task is a Data Mining Query task.
This package works fine in visual studio and when i deploy it to the server.
The problem i'm having is when i then try to execute the package from a job, after a bit of investigating i have tracked it down to the Encryption of "sensitive" properties. By default the encryption is based on UserKey which is why the package works for me when i execute it from VS or even the server, but when the job trys to execute the package running under the sql agent account it fails.
Looking at the security options i have for packages, i can either DontSaveSensitive, EncryptSensitiveWithUserKey or EncryptSensitiveWithPassword plus a few others.
DontSaveSenstive is clearly not an option as this just creates an unusable package.
EncrptSensitiveWithUserKey doesn't seem to be an option as the job runs under the SQL Agent account (also i'm thinking that the UserKey that the encryption is based on also incorporates other factors related to my profile that i can't impersonate? i might be wrong though)
EncryptSensitveWithPassword seems to be an option except that i can't get this to work either, there doesn't seem to be anyware in the job step to give it the password information.
Its frustrating me now because i've fallen at the very last hurdle, if anyone else has experienced this problem and knows how to resolve it that would great.
Thanks
Bob.

I followed the tutorial posted at [URL] ...
Everything was ok until the last step where I had to process the mining structure which resulted in a warning
"Informational (Data mining): Decision Trees found no splits for model, Tbl Decision Tree Example."
What does this error mean? How do I resolve it? Also, I only see the first level in the Mining Model Viewer, I don't see the levels 2 and 3.

Hi, all experts here,
I would like to know if there is any way to migrate third-party data mining packages with SQL Server 2005 data mining algorithms together then we can have a comparison among all of them to get the best results for training models.
I am looking forward to hearing from you.
Thanks a lot.
With best regards,
Yours sincerely,

Hoping someone will have a solution for this error
Errors in the metadata manager. The data type of the '~CaseDetail ~MG-Fact Voic~6' measure must be the same as its source data type. This is because the aggregate function is not set to count or distinct count.
Is the problem due to the data type of the column used in the mining structure is Long, and the underlying field in the cube has a type of BigInt,or am I barking up the wrong tree?

I'm a beginner with SQL 2012 SSDT & SSMS. I get this error message when I try to deploy my project:Â
"Error 6
Error (Data mining): KEY SEQUENCE columns are not supported at the case level. The 'Customer Key' column of the 'TK448 Ch09 Cube Clustering' mining structure contains content that is not valid.

"
I am finding it hard to locate the content that is not valid. I've been trying to find a answer for this problem but can't seem to find anything. How can I locate the content that is not valid and change or delete it so that I can deploy this solution?

Having successfully created :
- a data mining structure with about 80 columns.
- a data mining model using Microsoft_Decision_Trees with 2 prediction columns.Â
I thought I would then explore the possibility of have more than 2 prediction columns, in this case 20.
I get an error message and I can't work out :
a) if this is because there's a limit to the maximum number of prediction columns and where that maximum is stated.
b) if something else has become corrupted
c) there's a know bug and if the error message is either meaningful or not.
Either way, I'm unable to complete the data mining wizardÂ
The error message is :Errors in the metadata manager. Either the mining structure with the ID of '[my model Structure]' does not exist in the database with the ID of 'DMAddinsDB', or the user does not have permissions to access the object.

Hi all,
I am using Microsoft_Time_Series and have set HISTORIC_MODEL_GAP to various values (from 1 to 21). I always get this error:
Error (Data mining): The 'HISTORIC_MODEL_GAP' data mining parameter is not valid for the 'My Time Series' model.
In Algorithm Parameters window, this parameters is not there by default, so I have to add it.

Implementing data mining Add-in in an academic setting? We need to handle over 150 new students a semester and have their connection to Analysis Services survive for their four years at the college. We are introducing data mining to every freshman business student as a unit within their Intro to Excel class (close to a month of work to give them a sense of what is possible). Other courses later in their curriculum will expand on that introduction.Â
Once implemented, we would have as many as 900 connections to manage (four years from now). It is possible that multiple sections will be running at the same time, so 40 students may be accessing the data mining tools concurrently. Â
Is there a way to "bulk establish" the access credentials and establish those databases?

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,

Hi,
I am trying to model data in analysis services with the Advance Create Mining Model function in the excel addin. I am having trouble creating an association model that works like the Associate button above the Advanced button.
The format of my data is like this
OrderID Product
100 Bike
100 Helmet
100 Shoes
200 Helmet
200 basketball
200 Bat
300 Shoes
300 Socks
The associate button works perfectly since it asks me which column is the transaction id (orderid) and which column I am trying to predict (product). The advanced create mining model asks me to determine what the columns are...
OrderID=key Product=Input+Predict?
When I run the advance create mining model associate, I get a browser that gives me no rules and the support for only one item itemset (each product but no combination of products).
Does anyone know what I have to do to get it to work like the associate button?

I perform data mining on all products and a specific product category.
Do I need to create 2 data source views, one for all products and the other one for the specific product category?
Afterward, I run the Data Mining Wizard 2 times to create 2 mining structures.
I also need to add the same mining model (e.g. Bayes, Cluster) to each of these mining structures.
Is there any simple way to do it?
Thanks.

Hi everybody,
For our customer we are trying to create dynamically local cube files. Because the requirements are complex and we need to generate a lot of cube files, we can't use the MDX script CREATE GLOBA CUBE to create the local cubes and we have to use SSIS to have it done automatically. These are the steps we are following:
1. In a SSIS package, through a Script task, we generate the ASSL script in order to create the database and we stores the script in a column of the XML datatype in SQL Server through a stored procedure "SSAS_TEST.InsertASSLScript". The following code is use in the script task:
Code Block
Imports System
Imports System.IO
Imports System.Data
Imports System.Math
Imports System.Xml
Imports System.Data.SqlClient
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.AnalysisServices
Class ScriptMain
'Create writers and set formating for xml
Dim myScripter As Scripter
'Represents a writer to write information to a string
Dim myStringWriter As New System.IO.StringWriter()
Dim myStringWriterTrans As New System.IO.StringWriter()
'Represents a writer that provides a fast, non-cached, forward-only way of generating streams or files containing XML data that conforms to the W3C Extensible Markup Language (XML) 1.0 and the Namespaces in XML recommendations.
Dim myXmlTextWriter As System.Xml.XmlTextWriter
Dim myXmlTextWriterTrans As System.Xml.XmlTextWriter
Dim myXmlWriterSettings As XmlWriterSettings
Sub New()
myScripter = New Scripter
myXmlTextWriter = New System.Xml.XmlTextWriter(myStringWriter)
myXmlTextWriterTrans = New System.Xml.XmlTextWriter(myStringWriterTrans)
myXmlWriterSettings = New XmlWriterSettings
myXmlWriterSettings.OmitXmlDeclaration = True
myXmlWriterSettings.ConformanceLevel = ConformanceLevel.Auto
myXmlTextWriter.Formatting = Formatting.Indented
myXmlTextWriter.Indentation = 2
End Sub
Public Sub Main()

Dim sDBServer As String = CStr(oDTSDBConnection.Properties("ServerName").GetValue(oDTSDBConnection))
Dim sDBDatabase As String = CStr(oDTSDBConnection.Properties("InitialCatalog").GetValue(oDTSDBConnection))
Dim oBuilder As New SqlConnectionStringBuilder()
oBuilder.DataSource = sDBServer
oBuilder.InitialCatalog = sDBDatabase
oBuilder.ConnectTimeout = 1000
oBuilder.IntegratedSecurity = True
oBuilder.ApplicationName = "InsertASSLScript"
Dim oDBConnection As New SqlConnection(oBuilder.ConnectionString.ToString)
' Create Sql Command
Dim cmd As New SqlCommand("SSAS_TEST.InsertASSLScript", oDBConnection)
cmd.CommandTimeout = 60

cmd.CommandType = CommandType.StoredProcedure
' Add parameters and their values

cmd.Parameters.Add(New SqlParameter("@CUBE_XMLA", SqlDbType.VarChar)).Value = sASSLString
cmd.Parameters.Add(New SqlParameter("@DATABASE_ID", SqlDbType.VarChar, 255)).Value = sASDBName
cmd.Parameters.Add(New SqlParameter("@CUBE_ID", SqlDbType.VarChar, 255)).Value = "ALL CUBES"

'myXMLReader.Close()
myXmlTextWriter.Close()
'oDBConnection.Close()
oASServer.Disconnect()
Dts.TaskResult = Dts.Results.Success
End Sub
End Class
2. We manipulate the ASSL-script in order to create the cube that we want to have as local cube
3. We extract the final ASSL-script from the database through an "Execute SQL Task" with a XML Result Set. The SQL use in the task is:
Code Block
SELECT cast(CUBE_XMLA as varchar(max))
FROM SSAS_TEST.CUBE_XMLA
WHERE (COUNTRY_CODE = '500')
I have also tried
Code Block
SELECT CUBE_XMLA
FROM SSAS_TEST.CUBE_XMLA
WHERE (COUNTRY_CODE = '500')
and
Code Block
SELECT CUBE_XMLA
FROM SSAS_TEST.CUBE_XMLA
WHERE (COUNTRY_CODE = '500')
FOR XML AUTO
I always get the same error:
"Execute SQL Task: Executing the query "SELECT cast(CUBE_XMLA as varchar(max))
FROM SSAS_TEST.CUBE_XMLA
WHERE (COUNTRY_CODE = '500') " failed with the following error: "/ROOT/*[local-name()="Batch" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="Create" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="ObjectDefinition" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="Database" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="Cubes" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="Cube" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="MeasureGroups" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="MeasureGroup" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]/*[local-name()="Source" and namespace-uri()="http://schemas.microsoft.com/analysisservices/2003/engine"][1]

Does anyone know how to handle this?
If we could use this XML variable, we will use another Script task to generate our Local Cube(s). The script task looks like this:
Code Block
Imports System
Imports System.Data
Imports System.Math
Imports Microsoft.SqlServer.Dts.Runtime
Imports Microsoft.AnalysisServices.AdomdClient
Imports System.Data.SqlClient
Imports System.Xml
Public Class ScriptMain

I just converted several SSIS packages from SQL Server 2008 to SQL Server 2012. The packages having issues are those that are SSAS process cube tasks.
When editing the tasks in SSDT for SQL 2008, there is "Change Settings" button/option. In SSDT 2012, there is no Change Settings option!
What happened to it? Even when creating new packages, this option is not available.

Thank you very much for your kind attention.
I am wondering if it is possible to use SSIS to sample data set to training set and test set directly to my data mining models without saving them somewhere as occupying too much space? Really need guidance for that.

Now I have a different constellation: Integration Services run on one server, in version 2014, the Analysis Services instance to process the cube database on runs on another server, version 2012.I tried several different combinations of SSIS version and Analysis Management Objects version, and got several errors while running the process package (e.g. object reference not set to an instance of an object, cannot find AnalyisServices.dll..)
Is this combination 2014/2012 possible at all?I assume the BIDS version has to be for SQL Server 2014, as I want to run SSIS packages on a 2014 server, is that correct? Does it matter at all, can I also deploy 2012 packages?Which version of Analysis Management Objects do I have to use? I assumed I have to use version 11.0 here, because I want to process a 2012 cube?If it is possible to use the "old" 11.0 version of AMO, do I have to do anything so that it can be found by the SSIS package running on the server (it was built on my local computer, there I have all SQL Server versions from 2005 to 2014 installed in parallel), or do I just have to copy it to the appropriate SQL Server folder?

I've got a report that is using a cube as a data source and I can't get the report to show all the data. Only data at the lowest level of the cube is displayed. The problem is that most of the data I'm concerned with is at higher levels. There's no problem with the MDX. I get the correct results when I run the query.
I'm using a table to show the results. I've also tried a matrix, but I get the same results. I'm using SSRS 2005 and SSAS 2000.
Anyone have experience with this? Am I missing something simple?

I'm stucked in a problem and I thought if you would be so kind as to helping me to resolve it.
I'm implementing a clustering algorithm plugin for text mining. I've already read the tutorials and sample codes provided by the MSDN Library.
Well... My problem is: I can't go through the data when the Predict method is called. I've read that this method implements the "core" of the custom algorithms. Here is a small snippet of my code for you to understand my doubt:
STDMETHODIMP ALGORITHM::Predict(/* [in] */ IDMContextServices* in_pContext,/* [in] */ DM_PREDICTION_FLAGS in_Flags,/* [in] */ IDMAttributeGroup* in_pPredAttGroup,/* [in] */ DM_CaseID in_CaseID, /* [in] */ ULONG in_ulCaseValues,/* [in] */ DM_ATTRIBUTE_VALUE* in_rgValues,/* [in] */ ULONG in_ulMaxPredictions,/* [in] */ ULONG in_ulMaxStates, /* [out] */ DM_ATTRIBUTE_STAT** io_prgPredictions,/* [out] */ ULONG* out_pulPredictions) {
for(UINT i=0;i<in_ulCaseValues;i++) {
DM_ATTRIBUTE_VALUE& dmattributevalue = in_rgValues;
ULONG iAttribute = dmattributevalue.Attribute;
if (iAttribute == DM_UNSPECIFIED)
continue;
double dblValue = ::DblContinuous(dmattributevalue.Value);
char buffer[129];
sprintf(buffer,"%f ",dblValue);
RENAN_Log::log(buffer);
}
return S_OK;
}
As you can see, I'm going through in_rgValues to get its values, but i'm only obtaining the first register of the table on the database. I need to roll over a kind of resultset so I could access all the registers I need. Is there any way to do so ?
I expected Predict() received a matrix containing all my data, but the only thing I noticed that could represent the data is that in_rgValues vector. So I can go through this vector, but it holds only the first register of the table in the database (that's what's being saved on my log). I need all of the registers in order to pre-process the data and implement my clustering algorithm.
Well... That's it... I would be very pleased if you could help me.

I have very little experience with programming and data mining, but I am working on a project where I need to take data from one spreadsheet and place it in another. Since it is hard to describe what I would like to do, I will provide an example:
SPREADSHEET 1
Column 1, Column 2
100, ?
101, ?
102, ?
103, ?
SPREADSHEET 2
Column 1, Column 2
102, 202
100, 200
103, 203
101, 201
In this example, the data in Column 1 is always tied to the data in Column 2 (i.e., 100 in Column 1 means 200 in Column 2, etc.) However, the data for Column 2 is only available in SPREADSHEET 2; moreover, the data is not in the same order in both spreadsheets.
My question is how can I create some sort of program where I can transfer the data from SPREADSHEET 2 into SPREADSHEET 1?

Hi my friends,
I do have a problem with results of clustering algorithm with my categorical data.
In reality I have a big table with one's and zero's and I try to cluster according to 60 attributes.
I tries to cluster to two categories many times but I get only one cluster. What do you suggest. Which values can I change to the algorithm? Is there anything particular for categorical data ?
Thank for your help in advance.

Thank you very much for your previous answers conserning clustering algorithm.
I change a bit my data and now I can get two and three clusters as I wish.
But now I have a different question. I wish to keep my Structure and Model for further trials with different algorithm values, like cardinality. I tried the following
I selected in excel Data Mining and then the option cluster button.
Then in the cluster wizard I chose analysis service data source and I reform the query as I need adding only at the end
where "STAFF_YES" = 1. Then I choose the needed columns and target value. Finally I select browse model, enable drill through only and I finish the wizard and get some results, rather good. But i need to try again with different parameters.
I tried Business intelligent Studio to check my Analysis service. The structure were here but when I changed any parameter and I tried to reprocess I got the following messages
Processing Mining Structure 'try Structure_1' completed successfully.

I have a cube that tracks sales by sales rep. In this cube, I have dimensions for SalesRep, Product, and Region hierarchies. I also have a Time dimension that provides Fiscal Year, Fiscal Quarter, Fiscal Month, and Calendar Date; the Time dimension also has an attribute showing the first day of the year for any given date (our fiscal year starts on a different date every year).
I have a report that passes StartDate and EndDate parameters back to the cube, and provides sales numbers by Rep, Product, and Region for that given date range. What I would also like is a field that provides YTD sales through the EndDate parameter.
This is a piece of cake for me to implement against the SQL tables, but I am pulling my hair out trying to determine the best way to implement with a cube. Does anyone have any suggestions?
TIA

I have a vision of a beautifully interlocked Business Intelligence system in which I load dimensional fact tables through SSIS, build aggregations in SSAS cubes, and quickly and easily generate SSRS reports using the cubes as data marts.
I am now a month into trying to implement this vision and Reality is stomping all over it. Primarily, I am running into issues with the "cube as a data mart" idea. Each cube is taking up an additional gig or two of space, report queries against them seem to take longer than a straight SQL query against my fact tables, and I am running into serious problems trying to pass time-related calculations such as Year-To-Date to my reports.
Has anyone else tried setting up a BI system that uses cubes as the primary drivers for their reports? Have you seen any benefits to doing it that way? Or should I generate most of my reports through the SQL tables?
I'm nearing the point-of-no-return in choosing my final methodology, and any feedback would be greatly appreciated.
Thanks!

Dear friends,
I encounter a serious problem.
I would like to develop an application that can create Data Mining structures and a mining model in SQL Server 2005 with VB.NET. I tried the code from book Data Mining with SQL server 2005 in chapter 14 but did not work. Any good idea?
Please help me.
Best regards,
Manolis
