i begin for Data mining ( analysis manager - sql server 2000)
i create some mining model with Microsoft_decision_ trees or Clustering. it's oK
but now i want to create a model to know "If customer 1 has product A in their basket, what products should I recommend ".
i read and see that "Microsoft analysis manager sp1" have support association rules.
i install pack 4. but i don't see anything else . how i create a model with association rules.
Hello everybody,
I am interested in mining association rules field
I have found some posted statements but I didn't undertand them. I need your help badly.
Just tell from where should I start?
Thanks alot
Hello Everyone. I am a newbie to data mining. I hope that you can help.
I have run the same data mining query against the Decision Tree, Logistical Regession, Neural Network and Assocation Rules mining models. I created seperate tables to contain the results of each of these models. All of the tables have the same structure. The structure is a col#1 with a bigint datatype and col#2 with a numeric(5,5) datatype. All of the models have been successful with outputing the data to their respective tables except the Association Rules model. I am receiving the following error: " Failed to execute data mining query due to the following error: The given value of type SqlDecimal from the data source cannot be converted to type decimal of the specified target column." Is there something special that I need to do with my dmx statement to get the sqldecimal data to insert into the numeric column? What is different about the Association Rules model? I rechecked my dmx statement and it is the same for other models.
Let me know if you need more information.
Thanks
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.
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.
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?
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.
I'm currently running SQL Server 2005, and have been exploring the feasibility of grouping users to use a default file group and data file. This would be to group a set of users to have their new tables reside in a specific data file. I only see mechanisms for moving an already existing objects into a file group or to set the entire databases default file group--not a user level association or dynamic assignment of the default for that user, script, etc.
It's not looking good.
I'm looking for confimration that it's not possible or leads on doing so.
Thanx in advance
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.
Any tip will be greatly appreciated.
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?
With SASS Database i have created Data mining Structure Using Time series algorithm, while processing the SSAS db, Data mining  taking long time to process, so how we can  reduce processing time ???
View 2 Replies View RelatedHi,
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.
Joe.
Hi
I got a question about the data preparation of market basket analysis.
There are always some transactions with only one single SKU product. It seems that these kind of transactions have nothing to do with association. Shall I just exclude them or what?
Thanks in advance.
Hi, all here,
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.
Thank you very much in advance for any help.
With best regards,
Yours sincerely,
I have the most recent version of the MDS Excel plug in installed in Excel 2013, and am running SQL Server 2012 Enterprise. Â The Apply Rules button does not perform validation as it should. If I "Publish" data that does not conform to the business rules I have set up, it does return the proper errors indicating what rules have been violated; just using the "Apply Rules" button does not. I have twice gotten it to work momentarily by turning Show Status on and off several times in succession, but I have not been able to identify any consistent sequence that caused it.
View 7 Replies View RelatedHi. We're trying to setup a new case management system and I'm having a problem trying to store some of the information. I think I know how to go about it; however, I'm not sure if it's right.
We have two tables: Cases and Clients. The cases table stores relevant case information like case number, case type, etc. The Clients table stores information like name, address, phone number, email, etc.
What is the best way to associate these two tables together? I'm assuming I need a third table. Right? Thanks!
Hi all.Running SQL2K SP4 on W2K3 Standard, SP4.I have just refreshed a database on one server with a backup fromanother. The database had existed previously on the target server, andI am just refreshing its contents. I used the following approach1) From the target server, create a SQL script with users and roles2) From the source server, back up the db3) Transfer the file4) Restore the db, checking the location of the data and log files toensure correctness5) Remove orphaned users6) Run in the users/roles script generated in step 17) Run in a canned script containing object-level grants.I've done this dozens of times in other databases, but something alittle unusual has occurred here:My dbo user is orphaned. Normally it's associated with the 'sa' login,but at this point there is no associated user.I can see why this has happened - on the source db, the dbo user hasbeen associated with a non-default login.And, many of the objects in the db are owned by dbo.The only viable option I see is to change the ownership of theseobjects, drop dbo, re-add it with the association to sa, and reassertthe object-level grants.But what I would prefer is some way to change the association of thedbo user, to associate it with 'sa' without the need to drop andrecreate.Can anyone suggest an alternative strategy to associate a login and auser after-the-fact?Thanks much for all input!BD

View 1 Replies View RelatedHi there,
I'm wondering if there is a way to associate a job or task of some kind (i.e. SQL Agent job or SSIS package) with the generation of a report?
I have a need to provide an on-demand report that somehow initiates the updating of its data source prior to generation. In other words, I'd like the report to do *something* that can start an external process (external to the report) and wait for that process to complete before proceeding with the report generation.
As you can probably tell, updating the data source is expensive. It is normally scheduled along with a scheduled report, but I'd like the report to be runnable on demand when that is (rarely) the need, and I'd also like to guarantee the data source is updated when the scheduled report runs, which I can only do if I can somhow create a dependency between the updating process and the report generation.
Any ideas?
(The only way I can see to execute code synchronously from the report is to build a custom data processing extension/provider, which is fairly absurd.)
Thanks

Hello, im brand new to these forums, scrolled through a bit of the forum(mainly trying to figure out how to go about what im about to ask) and it seems like a good forum...anyways onto my question.
i am in need of ideas/know-how on how to structure a database like such:
its an online motorcycle accessories website, and this is the information i need to store in the db(basically these will be my tables in the db)
bike manufacturer
bike name
products
now my main question is how would i structure those tables so i can get this effect.
each product in the product table needs to have a bike associated to it, 99% of the time it will be more than one bike associated to it, so how would i go about doing that?
originally i had set it up with the bikes name being different columns in the products table with a bit type set to 1 if that product was available for that bike and 0 if it wasnt available. however as you are probably already thinking that isnt the best way to do that.
so what is the best way?
any info at all would be greatly appreciated.
thanks in advance
Currently a 2005 login has been granted sysadmin because I can not figure out how to grant the same login the SqlAgentUserRole. I thought I would use SSMS but there must be a trick. The role only exists in the msdb database, which the login has not been granted explicit access to. And the login does not appear in the list of Role Members or its sub windows. This should be real easy and intuitive . . .
Thanks!

I am trying to delete tables from data where the ModifiedDates older than 9 years in AdventureWorks2012 database . I get console notified that foreign keys are dropped but the delete statement is throwing errors. I am sure that somewhere the key constraints are not getting altered, but i'm not able to figure it out as i'm a relative beginner to T-SQL. The error and code:
The DELETE statement conflicted with the REFERENCE constraint "FK_SalesOrderHeaderSalesReason_SalesReason_SalesReasonID". The conflict
occurred in database "AdventureWorks2012", table "Sales.SalesOrderHeader

Hi, all experts here,
I am wondering is there any way to select only a portion of a data set to train the mining model? In this case, I mean we dont need to split the dataset in advance, what I want to do is being able to select any random portion of a selected dataset to train a mining model. Any advices?
I am looking forward to hearing from you and thanks a lot in advance for your advices and help.
With best regards,
Yours sincerely,
Hi all, I've had this issue in the past but dealt with it in a way that I don't think is correct:
Let's say I have a database on Server1. On Server1 I create a login and a user on the database. Now I have User1 with a login authorization on Server1 as well as a user within my database. If I detach that database now, and re-attach it on a different server, User1 exists. Of course, on the new Server2 User1 does not have authorization to login. I've deleted the existing user in the database and then re-created a login on the server, cascading through with the GUI setup to re-create the user within the database, too. Of course this gets ugly if the user has objects within the database. If I create a server login with the same name as the database user the login is not associated with the user too, correct?
I'd like to know the way that I can create a server authorization tied to the existing database user without dropping that database user, preferably within Enterprise Manager.
Thanks all,
MC
hi
I am new at MSSQL 2000 DBA thing. and trying to learn more about analysis service/data warehouse/data mining. so is any expert out there can Recommend some good books or web link article to read? Thanks
Could I ask how to spit the data into training and validation sets when doing data mining?
Thanks
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.
