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
Thank you very much for your help.
The errors that I can see in the code that you gave in your answer are the following and they are more or less the same as I had previously
I tried the code but initially I have encounter the following problems.
1. In any line that have the declaration As Server, As Database like in
Public Function CreateDatabase(ByVal srv As Server, ByVal databaseName As String) As Database gives me the problem that type Database is not declared the same type Server is not declared and it does not give me any option.
2. In addition to that for As DataSource, As RelationalDataSource, As RelationalDataSourceView, As ScalarMiningStructureColumn, As DataSourceViewBinding, gives me the problem that type is not declared.
3. Finally in mc = New MiningModelColumn("Yearly income", Utils.GetSyntacticallyValidID("Yearly income", Type.GetType(MiningModelColumn))) is not accesible in this context because it is 'Private'.
I have some more problems but I thing that by solving the above that I referred I will solve the rest.
Thank you any way.

Hi,
I've tried those two operations in the Management Studio.
Though we can create a mining structure and mining model in Management Studion,
but we cannot process the analysis-service database.
(1) I create only a mining structure through CREATE MINING STRUCTURE.
No error reported. But if I process the analysis-service database in Management Studio I always get error
'Error : The '<mining_structure__name>' structure does not contain bindings to data
(or contain bindings that are not valid) and cannot be processed.
I then tried to create it by creating and running an XMLA script. It was successful.
However, it's much harder to learn XMLA.
If any of you created an analysis-service database in Mgt Studio, and create a mining
structure in the same place using DMX script, can you process the database?
(2) Is there any use of CREATE MINING STRUCTURE operation without binding
to any table? Examples I saw so far did not show relating it to do. In my experience
processing the analysis-service database with that mining structure is doomed to fail.
(3) Is there any way we can create mining structure through CREATE MINING
STRUCTURE operation in Management Studio and use RELATED TO clause
to bind it to any Relationship to an attribute column (mandatory only if it applies), indicated by
the RELATED TO clause
(4) If this is the fact, is there any use of CREATE MINING STRUCTURE operation?
If we use BI Dev Studio, it's much easier to use the wizard.
(5) I found I cannot create a mining model inside a mining structure through operation
CREATE MINING MODEL. If you call that operation, you end up having a mining
model and a mining structure with the same name. I found that in order to create a
mining model inside a mining structure you have to call operation ALTER MINING
STRUCTURE ADD MINING MODEL. Is it true this is the only way?
Thank you,

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.
Joe.
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 get the following error when I try to load the mining model in the mining model viewer
Query (1, 6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[NeuralNet].[GetAttributeValues]' function does not exist.
I get a similar error when I try to load the Load Mining Accuracy Chart
Failed to execute the query due to the following error:
Query (1, 6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[AllOther].[GenerateLiftTableUsingDatasource]' function does not exist.
I have OWC 11 installed. What am I missing here?
Thanks
Hi ,all here,
Thank you very much for your kind attention.
I just found that I am not able to view the accuracy chart for my mining model. The error message is: no mining models are selected for comparision. Which is quite strange.
Any guidance? thank you very much.
With best regards,
Yours sincerely,
i have a problem, because i have 3 tables.
One name "CallPair" contain: id- identity number, from - phone number, to - phone number.
Second name "Talk" contain: id - identity number, callPairId - id from "CallPair" table, date
Third name "Transaction" contain: id - identity number is a number of transaction, idTalk - id from Talk table, callNr - number of talk in transaction
I want mining model to sequence clustering, but i don't know how build case and nested table
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.
0 0
"
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?
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 am not getting Mining Accuracy Chart and Min ing Model Prediction
Plz tel me how to do.And how to use the filter input data used to generate the lift chart and
select predictable mining model columns to show in the lift chart
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.
How to create a stored procedure to query the data mining model?
Where can I find some sample code?
Thanks.
Joe.
I am attempting to create the "Classification - Children at Home" Data Mining Model as described in Larson's book.
Each time that I create it.. ONLY the ALL LEVEL is shown and it is impossible to expand the model to look at the Decision Tree, Neural Network, or the Clustering model etc. Drill down is enabled (tried it with and without enabling the drill down).
The Children at Home field has been populated with values from 0 - 4.
Any ideas would be greatly appreciated.
regards Steve

Hi,
I am working with several tables, but for now I just mention 4 : one is fact table (named Usage), and 3 dimensional tables Periods, Products, and Regions. The fact table contains references to the dimensional tables. Table Periods contain two other columns month and year.
I created a cube containing columns from those 4 tables. Deployment was successful. Trouble comes when I want to create a mining structure using Time Series containing these columns :
- Period
- Amount (of money)
- Product name
- Region name
When I choose to use cube (instead of table) as source for mining structure, I'm forced to choose only one dimension (among the Periods, Products, and Regions). Whatever dimension I choose I end up being unable to use the column period as the Time-Key column. Effectively I cannot use Time Series method since I cannot use the column period.
(1) Why is this so [why Visual Studio forced us to use only one dimension from the cube] ?
(2) Why Visual Studio eliminates the column period, column that has relationship with the
time dimension?
(3) What is the use of Cube anyway to the mining? Is there still any use for it?
(4) What is the solution to that kind of problem I face?
Thank you,

Hi,
I'm working on a project to create a mining model.I have one "flattened" table with a productID (key) and related attributes. Example columns are weight, color, price, units sold last year, product category, product rating (top seller, etc) and similar columns, about 40 in total. There are about 15,000 products and same number of rows in the table.
The objective is to pass a ProductID (that also exists in the table) and get back the top N products that most resemble the source product based on all the attributes.
Any advice on which models I should test and how to set up the models would be much appreciated. Also if there is a similar example/sample out there, please let me know. I downloaded the MovieClick sample, but that doesn't work in my case as I only have the equivalent of the Customers table.
Thanks in Advance.
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 know, this is a common OLAP Error, but In fact I'm having trouble with this while trying to process a DM Mining Structure.
I'm currently working on a website that gets data from its users and analyzes it using SSAS. The thing is each time we add a new "analysis criterium" (sorry I'm trying to translate our french BI language in English...), we have to build a new mining structure, which needs data about users who have actually answered the question associated with this criterium. Some times, there are thousands, and some other only dozens, which is the case for the structure I'm having trouble with.
I got only 2 hundred tuples in the learning set. So lots of the common criteria weren't filled: I removed them using a stored procedure before feeding the structure, so that I got no column with only "null" values.
Of course, I know that 200 learning cases is really not enough to build an accurate model, but the purpose was just a proof of concept for machine driven Mining Structure building, and that was supposed to work even with so few cases.
When I process the MS, it fires: (Sorry it's in french, translation follows)
Erreurs dans le moteur de stockage OLAP : La clĂ© d'attribut est introuvable : Table : _x0032_0_EtudeIphone_Apprentissage, Colonne : EtudeIphone, Valeur : le nouvel iPhone (tĂ©lĂ©phone tactile et musical d€™Apple). Erreurs dans le moteur de stockage OLAP : La clĂ© d'attribut a Ă©tĂ© convertie en un membre inconnu parce que cette dernière est introuvable. Attribut Id de la dimension : 20_EtudeIPhone ~MC-Id de la base de donnĂ©es : ClassificationVDCE, Enregistrement : 2.
Badly translated it says "Errors in OLAP Storage Engine: Attribute Key not found Table:<StrangeTable> Column <MyPredictableColumn> Value <OneOfTheInterestingValues>
Errors in OLAP Storage Engine: Attribute key not found: converted to an unknown member. Attribute Id from dimension..."
Why? Too few cases? I have structures based on the same template but associated with other criteria and they work perfectly.
I'm ready to answer any question, and give any detail.
Thanks in advance.

Hi, all,
Just found that we are not able to define multiple key columns for a mining structure in SQL Server 2005 Data Mining engine, just wondering is there other way to define multiple key columns for a mining structure there? As in many cases, the table we are mining are with composite key consisting of different foriengn keys, e.g. A fact table are with transaction information and other foreign keys. If I am not able to define these composite key here for this fact table, I will have to have a named calculation in data source view to have a key column which is based on these original composite keys? Is this a better way to solve this problem or there is any other alternatives to figure it out?
Hope my question is clear for your help and I am looking forward to heaing from you shortly for your kind advices and help and thanks a lot in advance.
With best regards,
Yours sincerely,
Hello,
Can anyone spot what i am missing here ? The problem is that i am getting a null object for e.TextData in the t_OnEvent(object sender, TraceEventArgs e) function below. I am trying to get event- notifications while processing the data mining structure.
thanks

Mining Model Prediction... what for?
Which Data Mining algorithm use Mining Model Prediction?
Every algorithm has to use Mining Model Prediction for a final goal of a Data Mining Project?
hi,
I newly Installed my SQL 2005.When I try to train my Model its giving me "Key not valid for use in specified state." Can anyone help me how to figure it out?

i want create a model to predict what product i should Ads for customer at time.
example: in summer, i should show the , drinks (coca, pepsi) , ice food, bikini, sandals, glasses. in winter, i should show shoes, coats, hot food....
i have some table:
order(orderid, time,cusid...)
product(productid,..)
orderdetails(orderid, productid..)
customers(cuisid,....)
I have one main mining structure and several mining models that are using the MS Decision Trees algorithm. I have a Reporting Services report that displays the model using a table. I want to set it up so that in the DMX query, I can use a parameter to specify which model to use. That way I just have one report that can reference multiple models. For example I would like to do something like this:
SELECT FLATTENED * FROM [@model].CONTENT
This doesn't work because I get the error message:
Preparation of DMX query failed. Error (Data mining): Either the user, user, does not have permission to access the referenced mining model, @model, or the object does not exist. (Microsoft SQL Server 2005 Analysis Services)
We are running SSAS 2005 SP2. Is there a way to accomplish this?
Hi all,
I have MS Time Seeries model using a database of over a thousand products each of which has hundreds of cases. It amazingly takes only a few minutes to finish processing the model, but when I click Mining Model Viewer to view the models, it takes many hours to show up. Once the window is open, I can choose model for different products almost instantly. Is this normal?
Hi, all here,
Thank you very much for your kind attention.
I got a quite a strange problem with Mining structure for OLAP data source though. The problem is: I am not able to edit the mining structure in the mining structure editor. The whole data source view within the mining structure editor is greyed. Could please anyone here give me any advices for that?
Thank you very much in advance for any help for that.
With best regards,
Yours sincerely,
Hi,
I've tried to use the export command to export a mining model from management studio, but it returns that
export statement is not supported for OLAP mining structures, Ive checked the EXPORT(DMX) reference I can't see any note that it is not applicable on OLAP structures.
Can anyone confirm this?
