Hi, all here,
I am having a question about plug-in algorithms in SQL Server 2005. Since we are able to implement our own algorithms in SQL Server 2005 analysis services architecture, so my question is: what benefits can to a great extent be achieved? Like say, we are going to implement a plug-in algorithm, so what considerations should be concerned?
Thanks a lot in advance for any guidance and help.
Hi, all here,
I am having a more considertaion about Data Mining plug-in algorithms. When we say we are going to embed a uesr plug-in algorithm, so what is the context for that ? I mean in which case then we thing we need to embed a user plug-in algortihm? I know when we say we are going to embed a user costomermized plug-in algorithm, it means we want something more costomized. But what kind of customized features are generally concerned? Is it independant for different market sectors?
I dont think we can just try to embed a plug-in algorithm then compete it with avaialble algorithms to see which one is with better prediction accuracy?
Would please someone here give me some guidances about that?
Hi,all here,
Could please anyone here help me for this problem?
My problem is: I have registered my plug-in algortihm with SQL Server 2005 analysis services, and I can see my plug-in algortihm added to the analysis service configuration file (msmdsrv.ini). But why I can not see my algorithm appearing in the list of algorithms when I tested it? Really need help for that.
Thanks a lot for any guidance and help.
With best regards,
Yours sincerely,
Hi,
actually i want to implement a c# component that can help third party data mining algorithm
and i want managed plug-in algorithm (without wrapper),.
is it possible to write whole application in c#
as Analysis servisce is in c++ , can we implement it in c#
thanks in advance

Hi, all experts here,
Thank you for your kind attention.
Could please any of you give me some advices for if there are tutorials and demos avaiable which cover all the SQL Server 2005 data mining built-in algorithms?
That will be great to hear from any of you shortly. Thanks a lot in advance.
With best regards,
Yours sincerely,
managed plug-in framework that's available for download here: http://www.microsoft.com/downloads/details.aspx?familyid=DF0BA5AA-B4BD-4705-AA0A-B477BA72A9CB&displaylang=en#DMAPI.
This package includes the source code for a sample plug-in algorithm written in C#.
in this source code all .cs files are modified for clustering algorithm
if my plugin algorithm is of association or classification type then what modifications are requried in source code???
Hi, all,
Thanks for your kind attention.
Just wonder is there any good idea for us to select attributes for training models? Both for non-supervised algorithms like Association Rules and Clustering etc. and supervised algorithms like decision tree etc.
It will be much interesting to hear from you for any best practices and popular methods of dealing with this issue.
I am looking forward to hearing from you and thanks for your advices.
With best regards,
Yours sincerely,
Can anybody answer this question ?

I just want to know what are the data algorithms available for sql server 2005 and can i use data mining as a web service
Hi,
i'm making my master thesis about a new plug-in algorithm, with the LVQ Algorithm.
I make the tutorial with the pair_wise_linear_regression algorithm and i have some doubts. i was searching for the code of the algorithm in the files of the tutorial and i didn't saw it. I have my new algorithm programmed in C++ ready to attach him, but i don't know where to put him, in which file i have to put him to start to define the COM interfaces? And in which file is the code of the pair_wise_linear_regression algorithm in the SRC paste of the tutorial?
Thanks
I have installed the plug-in on two different virtual machines. On one, everything works fine, but on the other, the plug-in does not seem to load when Excel starts. I can see the plug-in the "Inactive Application Add-ins" section of the Excel Option Add-Ins panel, but when I check the two Add-in options in the "Manage Add-ins" dialog, they do not move up to the "Active" section. Stopping/starting Excel does not resolve the issue.
Any ideas on how to get Excel to make the plug-ins active?
Thanks ... bill burrows
I'm in trouble with my Plug-in Algorithm while filling out my model rowsets.
How to return ATTRIBUTE_NAME through GetNodeProperty if does not exist an ID to do it? Also it appears that no call is made for retrieve such node property.

I am in the stage of design for an application that uses SQL server 2005. We intended to encrypt some sensitve data using the encryption features in SQL server 2005. we will use symmetric key encryption. The question here is which symmetric encryption algorithm has the best performance? how much does the key size affect the perfromance? the data to be encrypted will be some lines of text equal to a word document.
any ideas?
Hi All,
We're currently preparing for a project for a bank client of ours where we would be using SQL Server 2008's data mining capabilities.
In the context of the out-of-the-box algorithms of SQL08 does the algorithms Logistics, Clustering and Logistic Regression includes Dynamic Logistics, Dynamic Clustering and Dynamic Logistic Regression?

Hi !!
I read that it is possible to create a custom algorithm and use it as a plug in to sql server 2005. What programming language are available for this purpose ? C++ only ? Can I use .net ?
Thank you!
Hello,
for an internship i am writing a data mining plug-in algorithm in SSAS in C#. My algorithm is a subgroup discovery algorithm and for determining the quality of the the discoverd rules/ patterns, i need to know what the support is of the rules.
The rules are of the form (a = x AND b < y THEN c = z). I managed to obtain some statistics by calling MarginalStatistics.getCasesCount(..,..). But I would like more functionality.
For example the data mining structure:
id | column1 | column2 | column3 | column4
1 1 1 1.0 1
2 1 2 2.3 1
3 1 2 1.1 2
I want to evaluate the rule (column1 = 1 AND column2 = 2 THEN column3 > 0). The result should be 2. Now is my question, how do i get the support of my rule in my in C# written algorithm?
Thanks in advance,

Hello,
I need to develop a Probit Regression Plug-In Algorithm.
Does anyone know if the plug-in framework will reasonably handle a Probit Regression?
Is anyone aware of any code or materials, specific to a Probit Regression Plug-in, that would help me to do this?
I am also interested in applying the dprobit methodology found in Stata for infinitesimal changes in independent variables.
Has anyone been successful using Stata to implement an SSAS plug-in algorithm?
thank you,

Hi,
In SQL Express SP2, when I select Tools > Options, there is a place where I am supposed to be able to specify the source control plug-in. I have SourceSafe 2005 installed on this machine, so I see these choices in the drop-down:
None
Microsoft Visual SourceSafe
Microsoft Visual SourceSafe (Internet)
The problem is that whenever I select one of the SourceSafe options, it goes back to "None".
I'm not even sure how the source control intergration works, but I figured I have to select the plug-in before doing anything else.
How can I select the SourceSafe plug-in under SQL Express SP2?
Thanks,
Mark
Hello Everyone,
I am reading DataMining Tutorial and right now I am at the Mining Algorithms section. I cannot understand any of the algorithms. For example take the following text... what a bunch of mouthful bla bla bla it is ....
"The Microsoft Decision Trees algorithm supports both classification and regression and it works well for predictive modeling. Using the algorithm, you can predict both discrete and continuous attributes.
In building a model, the algorithm examines how each input attribute in the dataset affects the result of the predicted attribute, and then it uses the input attributes with the strongest relationship to create a series of splits, called nodes. As new nodes are added to the model, a tree structure begins to form. The top node of the tree describes the breakdown of the predicted attribute over the overall population. Each additional node is created based on the distribution of states of the predicted attribute as compared to the input attributes. If an input attribute is seen to cause the predicted attribute to favor one state over another, a new node is added to the model. The model continues to grow until none of the remaining attributes create a split that provides an improved prediction over the existing node. The model seeks to find a combination of attributes and their states that creates a disproportionate distribution of states in the predicted attribute, therefore allowing you to predict the outcome of the predicted attribute"
In the above text what is meant by discrete and continious attributes? what is regression? what is predicted attributes? what are input attributes? what is distribution of states?
Is there a source which explains these algorighms in a easier way ....
hi,
Is it possible to use two algorithms together?I need to write prediction Query so that its should both models having clustereing algorithm and timeseries algorithm.
for example
I am having student information.I ve to predict performance of students for certain period.The students should be classified by their types like rich kids,poorkids..like that.I need to predict the performance of the rich kids??
can anyone help?
Hi,
In the info for SQL Compact Edition 3.5 it states that one of the features is:
Support for newer and more secure encryption algorithms.
I can't seem to find details of exactly what these new, more secure algorithms are. It appears 3.1 used 128-bit RSA. Is this the same in 3.5, or has this changed?
Thanks
I was just wondering on what algorithms was used in the different feature buttons in the Excel Add-In? For example, forecast, what algorithm was used in order for it to create the forcasting?

I recently started using SQL 2000 Analysis Manager. I wanted to try data mining but was unable to get the Mining Model Wizard to load available techniques.
When I select a cube and "New Mining Model" I get the following error:
"Unable to get list of data mining algorithms."

Please help.
Thank you very much,

I got an Assertion failed error while resizing a vector in a plug-in algorithm.
In order to isolate the problem I created a simple model class in Navigator.h file as shown below:
//========================= begin code =======================
class CStateStats
{
public:
DOUBLE m_dblSum;
DOUBLE m_dblSqrSum;
public:
CStateStats()
{
m_dblSum = 0.0;
m_dblSqrSum = 0.0;
}
};
class CAttStats : public DMHALLOC
{
public:
dmh_vector<CStateStats> vstatestats;
public:
CAttStats() : vstatestats (*this)
{
}
};
//========================= end code =======================
The access to DMHALLOC is provided in that class and in Navigator class as shown below:
//========================= begin code =======================
class ATL_NO_VTABLE NAVIGATOR :
public DMHALLOC,
public CComObjectRootEx<CComMultiThreadModel>,
public CComCoClass<NAVIGATOR, &CLSID_NAVIGATOR>,
public ISupportErrorInfo,
public IDMAlgorithmNavigation
{
public:
NAVIGATOR() : _viAttributeOutput(*this), _vCAttStats(*this)
//========================= end code =======================
I succeded making room for _vCAttStats vector, but when I tried providing room for the vectors of the vector I got an Assertion failed error (file dmhallocator.h Line:56 Expression assert(_dmhalloc._spidmmemoryallocator != NULL)). Please, see the code below, included in NAVIGATOR::GetNodeArrayProperty function:
//========================= begin code =======================
_vCAttStats.resize (2); // <<<<< succeeded here!
// make space for the states
_vCAttStats[0].vstatestats.resize(ulStates); // <<<<<<< assertion failed here!
//========================= end code =======================
I tried using a vector-of-vector approach and I also succeeded.
But I have to use that kind of structure: a vector of class with a vector inside.
I think I must provide a similar approach of vector-of-vector existing in DmhVector.h but I don't know how to do it.
I would apreciate any help.
When I installed VS 2005, it installed the default version of SQL Server 2005 Express that ships with Visual Studio 2005 installer media.
How can apply SQL Server 2005 Express SP1 to update this existing instance?
Currently, if I run this query:
SELECT @@version
I get the following:
Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86) Oct 14 2005 00:33:37 Copyright (c) 1988-2005 Microsoft Corporation Express Edition on Windows NT 5.1 (Build 2600: Service Pack 2)
After applying SP1, I should get 9.00.2047.00.
Should I just go to this link and download & install the SQL Server 2005 Express Edition SP1:
http://msdn.microsoft.com/vstudio/express/sql/download/

We have been using Sql Server 2005 Compact Edition 3.1 RDA synchronization method successfully on Sql Server 2000 database. Recently we moved the database to Sql Server 2005, sync doesn't work anymore, it just hangs on one table. On further investigation, we found out that it's the index on that table that causes this. We removed the index, it works fine. We are wondering the root cause, removing the index is not a solution for us. Any thoughts?. Thanks.

I have a SQL Server 2005 evaluation that has already been installed and setup on a server. I believe it originally had a 180 day eval. There have been numerous databases and users added as well as maintenance plan created...
The eval was put on the machine as an interim solution while waiting for paper work and order processiing things to happen. All the paperwork and ordering... have been completed and I now have the real SQL Server 2005 Standard Edition license key ....
I am very new to SQL Server and need to determine ...
1. Can I update the eval copy to become permanently licensed?
2. Would I want to upgrade the eval to permanent? Will I lose any capabilities by keeping the current eval setup?
If it is reasonable to keep the eval setup
3. How do I go about entering the license key to make it permanent?
If it is necessary to install the new Standard Edition...
4. How do I install it while maintaining the already defined databases, data, users, maintenance plan...
Thanks in advance for any and all help.
