Question Regarding Scenario On DataMining
Jan 22, 2007
Hi to all
I want to know how achieve the following scenario, I will highly encourage if anyone knows the solution please mention it through steps. The scenario is I have a table named €śCreditCardTable €? with following schema , the table is pretty much what one expect from a simple credit card application that will present form to user who fills the application of credit card and data going to be filled into the table. Later an analyst will review the data and will be accepting or rejecting the Credit Card along with some other fields as seen in the schema.
-----Schema --------
CustomerName Bigint
Age int
DOB DateTime
LimitAssigned Bigint
Analystname varchar
Salary varchar
Gender bit
Qualification varchar
Country varchar
JobTitle varchar
MartialStatus varchar
IsApproved bit
IsDeclined bit
Now what I want is that by using Microsoft Detaining Features after giving it the data t should purpose analyst the solution i-e (reject / approve ) the credit card application . Now I gather than there are many algorithms in SQL Server 2005 Analysis Services that can be used (Decision Trees , Association Rules ) , I research on the two I just mentioned and want to use Decision Tree for this purpose , but there is a bottleneck that is mentioned in a book named €śDetaining with SQL Server 2005 by Wiely€?. It says that the rules that the Decision Tree will build and use are not available to end user in contrast to Association Rule algorithm which provide the rules. I essentially need the rules by which the decision has been made. Please I really need help on these issue to summarize I need the following
1) With the table €śCreditCardTable€? I need to perform Decision Trees and Association Rules Algorithm on it , please provide me steps to do so , moreover please also mention how to specify Query (DMX I think) to get the final result i-e approve or reject based on the data .
2) The rules on basis of which the Algorithm makes it decision, please provide insights on how to achieve this by both Decision Trees and Association Rules Algorithm.
I really need an urgent reply on this , you can also email me at razi_rais@yahoo.com , thanks for your feedback.

i create a model mining to know percent of product, which is like more by customer is have percent biger than other products that is don't like by customer.
i use DTS to get result to sql server.
select flattened
predict([modelName].[tablePredict],Include_statistic)
from
[modelName]
prediction join
.....
i have result with a table A in sql server:
productid $support ... $adjustedprobability
1 0.0 ...
1 0.0 ...
1 63.3 .....
how can i write in Dts so that table A not have record with value $support=0.0
- second: percent people like that product is knowned by $adjustedprobability or $support and value small or big

Hello Experts,
I€™ve got a logical problem. I€™m just a newbie in this theme.
I build a cube with Analysis Services. It works and I can brows the cube.
For Example this could be a possible result:
Color
Red Blue Black Yellow
Auto brand
Opel 1 2
VW 2 1 4
Mercedes 1 1 2 2
The count shows us how much cars were stolen.
Now I try to build a Data Mining structure that shows me the behavior between the auto brand and the color. (To build the report I used Excel 2007 and the Data Mining AddIn)
After build the Mining Structure the Colum name are 1, 2 or 4 (just the counts).
To search for a better solution I tried to build the report manual. (Now it looked like that)
Auto Brand Collor stolen
Opel Red no
Opel Blue yes
Opel Black yes
Opel Yellow no
VW Red yes
VW Blue yes
VW Black no
VW Yellow yes
Mercedes Red yes
Mercedes Blue yes
Mercedes Black yes
Mercedes Yellow yes
Now the Column names are correct and the Data Mining structure is more understandable.
But the second report you can€™t build with a cube, because the Measures were just numeric.
My Questions:
- Where is my error?
- How do you build a Data Mining?
- Is there somewhere a tutorial could help me (I just founded tutorials that explains the different works of the different Data Mining Models)
- How would you build this problem in a Mining Structure?
Hope I don€™t forget some information and hear you soon
Yours sincerely,
Alex

Hi.
I am trying to predict the churn of a client for a cell phone company.
The thing is that the louse of many clients for the company incurred in hi level o churn and this is a problem; we don€™t want that to happened. So it would be helpful if I could determinate pre behavior of a client that is going to left the service.
So I put under analysis the next€™s values: (month of traffic,Minutes, Discount $us, antiqued of the client , time of payment, Month of Subscribe, flag (leave, stay))
Month that the client used the service.
So Minutes is the time that the client uses the service by mouth.
Discount, is the mouth of money that€™s been discounted to the client for any reason.
Antique, is the time in months that the client has the service.
Time of payment, is the time in months that the client pay ones has the bill.
Month of subscribe, means the date that the client subscribe the service.
Flag. The flag means if the client with this values stay whit the service or leave the service in a specific period of the year lest say June.
So all looks good, but this is the problem, just like I€™m trying to predict if the client stays or leaves, the size of the clients that leave the service is so small compared with the clients that stays (5 - 95) that the decision tree return only one node and says Stay 95% lease 5%, just like none of the values analyzed would make a difference. Thas why, I can€™t predict the louse of clients all do I have the all information about the clients that left the service.
Any idea, what I€™m doing wrong, or may be I need other information o less information.
Or maybe I should make my analysis in a different way.

The mining model viewer which comes with DM-Add in's works fine with Excel and also in Windows applications with the following code.
MIningModelViewerControl viewer = null;
MiningModel model=null;
MiningService service=null;
conn.ConnectionString = ConnectionString;
conn.Open();
model = conn.MiningModels[modelName];
service=conn.MiningServices[model.Algorithm];
if (services.ViewerType == "Microsoft_Cluster_Viewer")
viewer = new ClusterViewer();
else if (services.ViewerType =="Microsoft_Tree_Viewer")
viewer = new TreeViewer();
else if (services.ViewerType == "Microsoft_TimeSeries_Viewer")
viewer = new TimeSeriesViewer();
viewer.connectionString=ConnectionString;
viewer.miningmodelname=modename;
viewer.Dock = DockStyle.Fill;
panel.controls.add(viewer);
viewer.LoadViewerData(null);
But i need that as a web contorl to integrate with our existing web application but the viewer control is not working.
So is there another web control for viewing data mining models.
Regards,

I'm new to datamining and have gather some knowledge by following the tutorial that comes with sql server 2005.
I have following created a association mining model and tested it by using various DMX queries. I works quite satisfactory.
But I would like to use this mining model on a cube. Ie a calculated measure that would show top 1 recommendation for my customer portfolio.
My knowlede reaches to the extent that you need to feed data by using the OpenQuery or OpenRowset queries.
I would like to "stick" my model to the cube on some way and the extract values in the same manner as filtering criterias in stead of manually generating DMX queries.
I have googled a bit and searched MSDN without luck. Maybe I'm looking at this all wrong.
Is this possible?

Hello!
I am running a SQL Server 2005. I created the mining models from the tutorials. I can connect with the DataminingViewerClient directly on the SQL Server(i.e. to localhost), but when i try to connect to the Server from my other computer it is not working i always get connection faild and i should check that the server is running. I can connect to the Server with other programms but the viewer is not working. Any ideas what that could be?

Hello :
I have tried to process a datamining structure in SQL Server 2005 (Developer
Edition) but I receive these messages from Sql Server :
"Errors in the high-level relational engine. A connection could not be
made to the data source with the DataSourceID of 'Dbjao', Name of
'Dbjao'."
"Errors in the OLAP storage engine: An error occurred while the
dimension, with the ID of 'MCredito ~MC-Id', Name of 'MCredito ~MC-Id'
was being processed."
"Errors in the OLAP storage engine: An error occurred while the 'Class'
attribute of the 'MCredito ~MC-Id'
dimension from the 'CreditoAleman' database was being processed."
I generate this model from a relational table and can explore this
table
and build and deploy the project
But I receive these error message when I try to process the mining
structure
Do you have any idea which is the problem ?

Hi--
I am a newbie to datamining, but have nearly a decade of solid database experience with the last 6 years in SQL Server 2000. We are moving our accounting system to SQL Server 2005 and I have been asked to explore the possibilities of mining an inventory table. I'd like to get some opinions prior to spending too much time potentially barking up the wrong tree!
We have an inventory table with approximately 10 million serialized records. Each row contains the serial number of the individual unit and its manufacturer/model designation. We have no control over the assigning of the serial numbers as they come from multiple manufacturers and some of the manufacturers correlate serial numbers to model and some don't.
My thought was to use a cluster model to try to predict the model of a new serial number as it is entered into the database. Is this thought feasibile? Is the mining model choice appropriate? If pointed in the right direction, I'm sure that I can run with this.
Thanks in advance-- Jim

Hi to all
I have a complex scenario , so first I want to ask out the feasibility of it . I think its better if I state the scenario and some one on this forum reply to it , I need to build an application (e.g credit card application , Loan Application etc ) that requires some approval from expert , what I firstly want is that I apply datamining on this data so that next time when I enter the data the result (approval or reject ) should be given by datamining tool , this I gather is poosible by using Analysis Services in SQL 2005 , but I also want the bases of that decision ( I mean the rules/some thing else that the Datamining created agaisnt the data entered ) , So can any one do any help on this , you can also reach me at razi_rais@yahoo.com . its preety much urgent so your prompt response is higly appreciated.
Thanks and Regards

Hi
We are using SQL Server 2005 Standard Edition. I have SSIS package which uses 'Data Mining Query Task'. I am using this task to run the predictions using the mining model I have deployed. When I run this SSIS package from IDE , everything is fine. But I deployed this SSIS to msdb, and when I right click on the package and run it from MSDB I get error message saying ,
'Cannot run this task in this edition of Integration Services. It requires higher level edition'.
Altimately we want to execute this SSIS from an API which is written in C#. Can you please suggest any workaround for doing so?
Thanks,

Hi,
I downloaeded "Microsoft SQL Server 2005 Datamining Viewer Controls" feature pack, and tried to run the dataminingviewerclient.exe.
When i view my local time series data mining model, It works well for single series model, but when i load a Microsoft time series model containing multiple data series, an unhandled exception occurs.
I post the error message below:

Dear All,
I have a database table which has all the inputs, key and the result. In visual studio, I created a decision tree model which has exactly the same fields as in the table. However the visual studio automatically add space preceding the capital letters. As the field name in the Datamining model and those in the database table are slightly different. I cannot use NATURAL prediction join. Is there anyway to told the visual studio not to add the spaces in the variable names?
Thanks and regards,

I have a company with 5 offices connected with a dedicated line (500+ employees).
They have five databases, one in each office.
Now they want a new application which will replace the old (VB6 on MySQL will now be VB.NET 2.0 with MS SQL Server 2005).
The want all the data availiable in all the offices. We will still have 5 databases in 5 offices, but all with the same data.
Sometimes the dedicated line is lost.
Now I have a few questions:
Will the database be still running while a line is down?
Will the database be still running if replication is of type Merge (instead of continuesly).
Is it good practice to use unique identifiers versus Numeric keys?
Is it good practice when the application uses the "master" database to save global things like "Suppliers" and the local database to add and change Orders?
Do you have some recommended reads?
Thx for your time!

For High Protection mode (2servers, no witness, FULL safety), in the event of a catastrophic failure of the principal, can a remote (but well connected) mirror be forced to assume the principal role? The MS manual "Database Mirroring in SQL Server 2005" on p2 says the failover type for HP mode is manual only (as opposed to forced). Elsewhere it seems to seems suggest otherwise but there is no clear and unambiguous discussion describing the exact procedure.
Can anyone clarify this matter? Thanks,

I currently have a workflow "like" application which uses msmq to pass messages to each step transactionally. I'd like to take advantage to something like SSB to make the app scale. Here's how it works today:
Start Workflow WebService puts message on queue.
Windows Service has threaded listeners on each queue for the workflow.
The listeners do a transactional Receive off the queue. By doing this is in a transaction, we can enforce that only one listener will pick up and process the message. Once they have a message they call a .Net Assembly to perform some work. Once the work is performed succesfully, the listeners put the work context on the next queue using the same transaction as the receive and commit the transaction effectively removing the message from the receive queue permanently. If a fatal error occured during processing, the work context is moved to an error queue transactionaly. If the process blew up due to other reasons, the transaction is rolled back and the message reappears on the original queue so that another instance of the service can pick it up. Currently all this is running on one instance of the Windows service and cannot span more than one host machine since MSMQ did not support transactional reads off public queues without using DTC.
I saw the external activator sample and it looks great but I have a few questions. First, I'd have to modify it to call assemblies instead of external processes. No biggie there. One other requirement that one and only one receiver should process the message and that when the next message is sent to the next queue, it's done within the same transaction as the receive. I hope that this can be done without any deadlocks. I also saw mentioned somewhere that this messaging could advantage of the local SQLExpress instances so that even if the main SQL Server instance is down, the messages can go out. Last requirement is that our message is a blob (serialized .Net object) so how do we define that kind of message?
Thanks

Table1: WriterID, WriterName, WriterSurname
Table2: BookID, WriterID, BookName, Category
Table3: CategoryID, CategoryName
There will be one form. Which way i should use to enter data from one form to multiple tables with same WriterID.
1.) Should i use SqlCommand class and a Stored Procedure?
( Like that: http://www.aspnet101.com/aspnet101/tutorials.aspx?id=13 )
2.) Is there another way without a stored procedure? I can't imagine how to insert same form to multiple tables. In real scenario there are lots of table and all contains a column that holds same value such as WriterID.

Hi, I want to know the a solution for my Synchronization Scenario
I have a several client databses which are SQL Server 2005 Express and i have a master database which is SQL Server 2000 containing all the individual Client databases. All the individual client databases are kept seperately at the master location. I need to Synchronization the client database with its copy at the master database (something like Merge replication). Both the Client Copy as well as Master Copy could be Publishers & Subscribers.
Now the problem is Because of security & firewall issues, only the Client should have the ability to schedule & initiate the synchronization process with the master copy. Unfortunately SQL Server 2005 Express has only subscriber agent and not a publisher agent.
Any help on how to achieve this would be appreciated . Thank You

Hello All ..
This is the scenario I'm having :
-- I'm a beginner so bear the way I'm putting it ... sorry !
* I have a database with tables
- company: CompanyID, CompanyName
- Person: PersonID, PersonName, CompanyID (fk)
- Supplier: SupplierID, SupplierCode, SupplierName, CompanyID (fk)
In the Stored Procedures associated (insertCompany, insertPerson, insertSupplier), I want to check the existance of SupplierID .. which should be the 'Output' ...
There could be different ways to do it like:
1) - In the supplier stored procedure I can read the ID (SELECT) and :
if it exists (I save the existing SupplierID - to 'return' it at the end).
if it doesn't (I insert the Company, the Person and save the new SupplierID - to 'return' it at the end)
------------------------------------
2) - Other way is by doing multiple stored procedures,
. one SP that checks,
. another SP that do inserts
. and a main SP that calls the check SP and gets the values and base the results according to conditions (if - else)
3) it could be done (maybe) using Functions in SQL SERVER...
There should be some reasons why I need to go for one of the methods or another method !
I want to know the best practice for this scenario in terms of performance and other issues - consider a similar big scenario ..... !!!
I'll appreciate your help ...
Thanks in Advance . ! .

How can I be able to use "NewReceivedTime" as a variable?
Since having to create a new column using CASE statement in SQL would mean that user will not be able to use this new column name and having to receive error such as "Invalid Column Name: NewReceivedTime "
(case
when <value>
else <value>
end) as NewReceivedTime
I'm asking this because, I would want to use "NewReceivedTime" I've created to equate to another Time Column like
NewReceivedTime = LogDateTime something like that.
Thanks.

What I'd like to do is use SQL Express as a back-end for an existing Access 2003 application. The application is currently a single-file Access solution. I'm just investigating options to separate the front-end from the back-end so that the users can access a single data store from multiple PCs. We're only talking about maybe 5 users total, and really no more than 2 accessing it simultaneously at any given time (although the same setup exists in several offices). Right now they are just opening the Access db from a fileshare. This has resulted in corruption on a few occasions, which is part of the reason for wanting to replace the current solution with something that will be a little more robust. I'm wondering if there is a way to deploy a SQL Express db on a fileshare so that it can be connected to by the Access front-end. While we can install things on their desktops, we can't install anything on the file server, we can just put files there. Is there any way that I could make that solution work, or should I just stick with separating the Access front-end and back-end?
Thanks,
Kris

Hi all,
I have a huge replication task I need to perform. The source table has over 250,000,000 records and everyday approximately 400,000 records are added to the system regularly.
Currently, I am running snapshot replication and it's taking 10 to 11 hours to complete (The internet connection between the production and the report server is slow). The reason I am using this method is because the source table does not have a timestamp column (so I can run an incremental replication) and I cannot modify that table because it belongs to a third party software. It does have a field which is linked to another table holding the timestamp.
Here is the source table and the other table's structure for reference:
DataLog
Name Datatype Size
DataLogStampID int 4
Value float 8
QuantityID smallint 2
DataLogStamp
ID (Which is foreign key to DataLogStampID field in the above table) int 4
SourceID smallint 2
TimestampSoruceLT datatime 8
What I would like to know is, what is the best practice to handle such replication with MSSQL Server 2000.
I am thinking of developing a procedure which follows the following step using a temp table:
This procedure will run (say) every night.
The temp table will contain a timestamp field.
For one time only, I will run a snapshot replication, so that I can have the existing data into the destination db.
I will record this timestamp into a repl_status table which holds the timestamp of the last replication.
The procedure will read the record from repl_status and select all records from the source table which were added since this date and put them into a new temp table (this table will have the same structure as the source and destination tables) and then a snapshot replication will "add" these new records only every night to the dest. table. By using this method, I will only transfer the records which have been added since the last replication (last night - less records).
Any comments would be greatly appreciated.
Thanks for your time in advance,
Sinan Topuz

Hi,
I am faced with a scenario where I have to predict the time period that will
required to solve a particular problem depending on various factors like
Problem Type, Severity Level, Resource Availability etc.
I would like to know which algorithm is best suited for the
above scenario and the reasons for the same.
