hi, i am bit new in the field of data warehousing and data mining but catching up fast. I am in the last year of BS(Computer Science) and intend to do a project on a Business Intelligence but i was wondering can i get a sample dummy data for my work is that any way possible??
View 1 RepliesHello
I'm looking for sample database for data mining in SQL Server 2005. In my project I need to use all algorithms provided by SQL Server 2005. I know that we have "SQL Server 2005 Samples and Sample Databases" on microsoft.com site, but there are only AdventureWorks data sets. I need sth less popular, but similar.
I have found http://www.kdnuggets.com/datasets/index.html and others, but I don't see data sets good for multidimensional analysis.
The origin of data may be natural or artificial, it doesn't matter.
I don't have to generate my own data, because I had to discover new knowledge, that will be surprising to me.
Any help would be appreciated.
Thanks in advance.
(sorry for my English)
Hi, all here,
Thank you very much for your kind attention.
I dont think we should sample any nested tables for data mining model training? Since I think any nested tables are bound to the case table. Therefore whenever we sample the case table, the nested tables are like any other input attributes within the case table to be rectrieved as inputs accordingly?
Thank you very much for any guidance to clear my confusion.
With best regards,
Yours sincerely,
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.
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, 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,

Hi
Books online mention the existence of sample code for several custom tasks, including the one mentioned in the title. But, when I try to find this code in the location mentioned it is nowhere to be found.
I have run a search on the rest of my drive and come up empty.
Can anyone tell me where to find this?
Thanks

Here’s a more in depth breakdown of my problem:
We have 4 regions, currently we only have 3 servers in the field, and therefore only 3 regional id’s are being used to store the actual data of the pbx. The central server (RegionalID = 0) is holding the data for itself and the 4th region until the new server is deployed.
It now has to be deployed and therefore the data migration for this region has to take place.
I am trying to extract all the data for this 4th region (RegionalID= 1) from the central server database from all the relevant tables.
When doing this I will firstly, have to check that the CallerID is valid, if it is, send that entry along with the result set, if it is not valid, Check that the dongle area code is valid, if dongle area is valid select with the result set, and if it is not valid, then check that RegionalDialup = ‘0800003554’ which is the dialup number for this 4th region (RegionalID = 1).
I have a table named lnkPBXUser which contains the following:
if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[lnkPBXUser]') and OBJECTPROPERTY(id, N'IsUserTable') = 1)
drop table [dbo].[lnkPBXUser]
GO
DDL:
CREATE TABLE [dbo].[lnkPBXUser] (
[RegionalID] [int] NOT NULL ,
[pbxID] [decimal](18, 0) NOT NULL ,
[userID] [decimal](18, 0) NOT NULL
) ON [PRIMARY]
GO
Sample data:
INSERT INTO lnkPBXUser(RegionalID, pbxID, userID)
SELECT 0, 543, 2 UNION ALL
SELECT 0, 10961, 6 UNION ALL
SELECT 0, 1012, 17 UNION ALL
SELECT 0, 16499, 26 UNION ALL

Ok, I am dealing with the lnkPBXUser table at the moment,
I need to be able to join lnkPBXUser and tblDialupLog, then compare tblDialupLog.CLI to tblCodes.SubsNDCD + tblCodes.LocCD (when these two columns are concatenated the result will only be a substring of tblDialupLog.CLI. (this is to make sure that the CLI exists in tblCodes.)
If it does exist, then it is part of the fourth region and should be returned in the result set.
If it does not exist, I then need to check that tblDongle.DongleAreaCode is a substring of tblDialupLog.DongleAccessNumber.
If it is a valid DongleAreaCode for that region, then it is part of the fourth region and should be returned in the result set.
If it does not exist, I then need to check that tblDialupLog.RegionalNumber = ‘080003554’.
So from the above tables an expected result would be:
RegionalID pbxID userID
0 1012 17
0 543 2
Please assist, it would be greatly appreciated.

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,
I'm working with the sample database called Adventure Works and I'm encountering data consistency issues :
If I sum the TotalDue for one particular territory, for one particular time window from the Sales. SalesOrderHeader table and if I try to compare the result to the LastYearSales and YTDSales from the Sales.SalesTerritory table, I don't get the same number, whatever I try. So did I miss something ?
How are the LastYearSales and YTDSales fields from Sales.SalesTerritory calculated ?
Thx,
Anissa
