OLTP Vs OLAP (Data Warehouse) As A DataSource In Analysis Services 2005

Jul 3, 2007

Hello,Can I import an OLTP (Reltional DB) as a Data Source into SQL ServerAnalysis Services 2005 and then use the Cube Wizard and the new DataSource View feature to create the OLAP model ?Or do I have to first design an OLAP Data Warehouse with a Star Schemaand then import this DW as a Data Source into my Analysis ServicesProject.With SQL Server 2000 , OLAP would be the way to go..but with SQLServer 2005 , it seems as though the wizard and data source viewfeatures do half the work for you.I have an OLTP DB and am not sure which route I should take ! Anysuggestions / input would be much appreciated.Thanks in Advance...RegardsRusszee

Licensing Of Data Mining Tools With SQL 2005 Analysis Services

Oct 25, 2006

A rather dumb question but I've installed an evaluation copy of SQL 2005 on my machine and a colleague would like the Analysis Services Data Mining capability on his machine (without the eval SQL Server).

Is there a license associated with such an installation when we buy 2005 or does it fall under client components which can be installed on any number of users machines?

Data Mining - Scalar Mining Structure Column Data Type Error...

May 31, 2006

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?

Data Mining :: MS Excel Data Mining Add-ins / Maximum Number Of Predict Columns

Jun 4, 2015

Having successfully created :

- a data mining structure with about 80 columns.
- a data mining model using Microsoft_Decision_Trees with 2 prediction columns. 

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 wizard 

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.

Sampling Data Set Via Integration Services Data Flow For Data Mining Models Without Saving Training And Test Data Set?

Nov 24, 2006

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,

Data Mining :: Implementing Excel Data Mining In A Classroom Setting?

Jun 15, 2015

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. 

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.   

Is there a way to "bulk establish" the access credentials and establish those databases?

Where Can I Store The Mining Results From Mining Models In SQL Server 2005 Data Mining Engine?

Apr 26, 2006

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.

SQL Server Admin 2014 :: Change Data Capture(CDC) For Data Warehouse / Reporting?

Aug 12, 2015

I have a requirement to implement CDC for 50+ tables to implement incremental data changes warehouse/reporting rather than exporting the whole table data. The largest table is having more than half a billion records.

The warehouse use a daily copy of OLTP db (daily DB refresh). How can I accomplish this. Is there a downside in implementing CDC just for the sake of taking incremental changes on the tables?

Is there any performance impact if we enable CDC on OLTP db?

Can we make use of the CDC tables on the environment we do daily db refresh so that the queries don't hit OLTP database?

What is the best way to implement CDC to take incremental changes for reporting.

SQL 2012 :: Data Modeling Tool For A Data Warehouse?

Oct 19, 2015

I need a recommendation on a data modeling tool that can be used with a data warehouse. My warehouse is running SQL 2012.

Here is my challenge: Most of the tables in the warehouse do not have primary keys and none of the tables have foreign keys on them. However, there are indexes and unique keys/indexes on the tables. I am looking for a tool that I can create virtual relationships on how the data is related, so it is visually easier for the ETL developers to write the code.

I have looked at both ER/Studio 11 and ERwin 9.6. Neither of them do it exactly the way I want it too. However, ER/Studio is pretty close.

Recover Sql And Analysis Service Data From Disk Crash

Feb 13, 2006

Cristiano writes "hi everybody.
A customer of mine has had a disk "crash" few days ago.
I wrote for him a dwh application and
of course the backup was not working...


now some "hardware guys" said that it is possible to recover most of
the files.


what I need to restore would be:
1- the sql server db
2- the sql server dts and jobs
3- the analysis service cube and dimensions


to do so is it enough for me to have:
1- the .mdf and .ldf files
2- the master.mdl /.ldf file
3- the .odb file and .dim* and .role .map ... files


right?
is it enough to recover everything?
if it is so, what would be the right processes to recover everything? "

Data Warehouse And A Data Base? Difference?

Jun 19, 2007

I need someone to give me a small briefieng on how a enterprise data warehouse (EDW)differs from a regular database?
Currently we have an appplication that accesses a database with about 18 tables. We also have a Data Warehouse. For some reason I was thinking that it would be possibly to migrate thedatabase into the data warehouse. The reason is that in looking at the schematic design forthe data warehouse there are some data tables that could also be used by our application that uses the DB.
I guess I am confused because I am not sure if a data warehouse is used in the same wayas a database?

How Is The 'Score' Value Derived In The Lift Chart/Mining Legend For Data Mining Models?

Sep 26, 2006

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,
S Rajput

Excel 2007 Data Mining Add-in Advance Create Mining Model Question

Apr 11, 2007

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?

Can I Filter The Data On Mining Structure, Mining Model?

Jul 18, 2006

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.

Database For Data Warehouse

Dec 22, 2004

I am going to use Microsoft SQL Server to develop my data warehouse, but one thing makes me confused. Since Analysis Service can create a Star schema database, do I have to pre-set up a Star schema database for ETLed data? Basically, I am wondering what's the relationship between an ETLed database and the one created through the Analysis Services.

Can any one give me an explanation from the implementation perspective?

Many thanks!

Help With Restore Data Warehouse

Feb 27, 2008

Hi all,

I am trying to restore my data warehouse from a January 2008 backup under a new name to recover a table that I accidentally deleted. It is taking a long time for the restore to get done. Here is the command I am running as sa in QA

---

RESTORE DATABASE Warehouse_new FROM DISK = 'H:MSSQLDataMSSQLBACKUPDBBackupsWarehouseWa rehouse_db_200801050600.BAK'
WITH
MOVE 'Warehouse_Data' TO 'G:MSSQLDataMSSQLDataWarehouse_New_Data.MDF',
MOVE 'Warehouse_Log' TO 'H:MSSQLDataMSSQLLogsWarehouse_New_Log.ldf'

----

There Warehouse_New_Data.MDF is 375 GB and the log is 12 GB.


There is still 169 GB of free space on the drive I am restoring to after the presence of Warehouse_Data.MDF and Warehouse_New_Data.MDF (each 375 GB).

Its been 4.5 hrs and the restore is still running. Backups take about 3.5 hrs to complete. Can I do any checks on the restore to see what point it is at? I stopped the restore using EM earlier after it took 8 hours and still no progress.

Please advise.

Thanks.
