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?
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.
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?
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.

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?
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:
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?
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.
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?
I need to create a query that will pull all of the records that are statused as 'OUT' from my RECORDS table and then get the last (chronologically) 'OUT' record from my IN/OUT table for each record it pulled from RECORDS.
I can get the records out of RECORDS without any problems but I don't know how to set up a query that will pull the last chronological 'OUT' record from my IN/OUT table. Is there a way to do this in SQL?
company is developing a database system containing information about cities, towns, and villages in the country. The number of cities, towns, and villages are in thousands and the database program should allow users to search a particular place by name. Users should also be able to search all places that match a particular value or range of values for attributes such as location or population size. This particular feature is known as a range query.
If the database is meant to support range queries that can return many cities that match the query specification, the entire operation may be allowed to take longer. To meet this requirement, it will be necessary to support operations that process range queries efficiently by processing all cities in the range as a batch, rather than as a series of operations on individual cities.Different indexing methods can be used to perform this operation. What will be your choice if:
a) database is created once and has no change over a period of time
b) database is created once and database is changed over a period of time
Good Day;I would appreciate assistance developing a query that I haven't beenable to develop without using a second table. I wish to count thenumber of records that are still open on the first of each month.Each record has an open date and a close date or the close date isnull i.e., the record is not yet closed. I've previously beaten thisby building a table, simply a list of the dates for the first of eachmonth for the next ten years or so, and then selecting values basedupon a date selected from that table. However I'd be happier if Icould do it without the second table. I'd be prepared to accept theMin(Date) for each month as being the first of the month.I've included some DDL statements to build and populate the table ifthat helps. Since the selection is rather small and all the opendates are very close together I think the result will be simply adecreasing count from the month the first record is opened till today.A pseudo code select statement might look likeSelect Min(DateOpened) As DateOfInterest, Count(*) as [Qty Still Open]FROM DetailTWhere DateReceived > DateOfInterest or DateReceived is Null andDateOpened < DateOfInterestGroup by Min(DateOpened)Order by Min(DateOpened)I hope I've explained it sufficiently well.CREATE TABLE [dbo].[DetailT] ([Autonum] [int] IDENTITY (1, 1) NOT NULL ,[QDNumber] [varchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ,[DateOpened] [smalldatetime] NOT NULL ,[DateReceived] [smalldatetime] NULL ,)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C15788', '06/04/2005 9:35', 07/04/2005)Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B16091', '06/04/2005 9:36', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('B15001', '06/04/2005 9:51', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('M18696', '06/04/2005 9:56', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('C14969', '06/04/2005 10:05', '10/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('O10091', '06/04/2005 10:08', '12/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('D01197', '06/04/2005 10:13')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('H15001', '06/04/2005 10:15', '08/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('J15090', '06/04/2005 10:24', '08/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('J01202', '06/04/2005 10:31')Insert into DetailT (QDNumber, DateOpened)VALUES('G01193', '06/04/2005 10:32')Insert into DetailT (QDNumber, DateOpened)VALUES('K01164', '06/04/2005 10:35')Insert into DetailT (QDNumber, DateOpened)VALUES('K01162', '06/04/2005 10:48')Insert into DetailT (QDNumber, DateOpened)VALUES('F01124', '06/04/2005 10:59')Insert into DetailT (QDNumber, DateOpened)VALUES('H01147', '06/04/2005 11:01')Insert into DetailT (QDNumber, DateOpened)VALUES('S15068', '06/04/2005 11:10')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('E12322', '06/04/2005 11:32', '07/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('A12205', '06/04/2005 11:37', '06/04/2005')Insert into DetailT (QDNumber, DateOpened, DateReceived)VALUES('D12259', '06/04/2005 11:40', '07/04/2005')Insert into DetailT (QDNumber, DateOpened)VALUES('C03394', '06/04/2005 11:51')If you made it this far thank you for your patience.

I am in the planning stages of a front-end to access sql server databases. The project involves analysis of stored data as well as storing results of the analysis. The classes for the analytical part is fairly complex so I would like to speed up the data manipulation part of the project. I am already familiar programming with ADO but I was hoping for a more complete solution. Is there a sdk or example code (third-party OK) that could facilitate this?
The client is not especially fond of .NET and would prefer to use VB6. However, with the right solution, C# or VB.NET would be acceptable languages.
I'm beginning development on a medium/ sized in-house web based system. Well moving from asp/mysql to asp.net/sql server. Re-doing DB design as well.My question is does it make sense for me to develop the SQL DB in Visual Studio 2005 pro, and then later move it to a real SQL server? Or basically what is the best and/or most practical way to do this development. Any other IDE's out there?Thanks
I am developing a Translator for a mobile phone and I am using MS SQL server 2005 for creating my database.. I am having a problem in creating a relationship between my tables.. I have the following tables: English(engcode,engword) - engcode is primary key Esperanto (espcode, espword) - espcode is promary key EngEsp (engcode,espcode)..
The problem is that the icon "relationship" is disable in sql 2005 and i am nt able 2 create the relationship..
I am trying to write a program that creates packages on the fly depending on the variables you pass. for eg. It should create connection managers on the fly specific to a certain file in the variable (eg. sample.csv). the package has a dataflow task and it has flat file source and oledb destination.The problem I am facing is the flat file source when assigned to a flat file connection manager(dynamically), it is not giving any source output columns. i.e, the value for DFSource.OutputCollection(0).OutputColumnCollection.Count is Zero. But when I use the same code and reverse the source and destination(oledb as source and flatfile as destination), it is working fine. I searched everywhere for resources on how to develop packages programmatically, but could not find any except one example on msdn. If anyone knows about this prob or any useful resources on this subject, it would be really helpful.
I have .NEt web application where i have to tranfer large number of records (50,000 to 1,00,000) from one DB to another DB.I want to use ssis pacakge to do this task , but my requirement is to build this ssis pacakge dynamically using .NET framework.
Is it possible to develop SSIS pacakge from scratch using .net programming? Suggest me any other alternative options if you have ?
I have the full version of SQL Server installed on my machine and am developing an app using BI DTS packages, VB.Net, SQL SPs, etc.. I will need to deploy this app w/SQL Server Express (SSE).
-Do I have to install SSE on my development machine for the purpose of creating the install package of my application? I am afraid that if I do install SSE on my machine, it may mess up my installation of the full version of SQL Server... will it?
-Can you point me to a link with information about how to do the development with the full version of SS, and create the installation package using the SSE?
I am new to SQL 2005 CE but fairly experienced with SQL 2000 and know my way around SQL 2005. I am creating a PDA app that must support the following scenario:
My company has a SQL 2000 server with a "computer assets" database. This asset database must be able to be transferred to an .sdf file (SQL 2005 mobile) on the PDA when the user docks their PDA to the desktop PC (not the same machine as the SQL 2000 server). This transfer can be via an option in the mobile app that is initiated by the user, or automatic.
The mobile application basically supports stock-taking of the assets, so users go out on site and record information about the assets. This information is stored in a separate .sdf database on the PDA.
When the user gets back to the office they dock with their desktop and then must transfer the data from the second .sdf database onto the SQL 200 server. Lets call this the "asset metadata".
thats basically it! but im having issues finding the right process to attack the data transfer tasks.
- Firstly, how do i populate the .sdf on the PDA for development purposes? Microsoft tutorials seem to be geared at SQL server 2005 management studio only. I only have SQL server 2005 Management Studio Express on my development machine as well as all the necessary SQL 2005 CE SDKs and VS2005. We do not use SQL Server 2005 at my organisation as yet and it will be some time before we migrate across. In effect im looking for something that behaves like a DTS package to transfer data across.
- How to populate the "asset database" .sdf file from the SQL 2000 server when the user has docked to their desktop PC? (This needs to be refreshed )
- How to transfer the "asset metadata" from the .sdf on the PDA to the SQL server?
ive looked at merge replication a little but am not sure whether this is what i need and again most online information seem to be tailored to SQL Server 2005.
Can anyone kindly point me in the right direction?
There seems to be a BUG in BIDS when developing SSIS packages using the Import/Export Data wizard.
If you use the wizard to import a large number of tables, and then select all the tables, and then choose to delete exisiting data in each table, the PrologueSQL file does NOT get built correctly. Instead of having a
TRUNCATE tablename Go
for each table, it just has a bunch of "Go"s with nothing between them. In the step immediately prior, where you confirm what the wizard will do, it tells you, after each table, that it will delete any existing data...but it doesn't do this.
If, during the wizard, I select each individual table one at a time and tell it to delete existing data, then it will get built correctly, but not if I select them all at once...YET, if I do select the whole block, choose delete existing data, and then select any single table, it shows that table as being set up to delete existing rows.
This is very frustrating when trying to import large numbers of tables.
I need to find all information about distributing SQL Server XE and applications using it . Is it legal ?? should it be used just for educational use?!!! could it be used to develop a commercial software !! what limitations are controlling this ??
We started to develop a datawarehouse solution for client back in December 2008 based on SQL 2008. We are convinced that we can use some of the new feature included in the new version which is the reason we we chossed to go down this path.
Due to the delay of the next version we have some question that I would like to hear you opinion on.
The estimatet "go live" date is during spring (march/april)
Is it wrong to contiue the development on the 2008 version?
We would need to run Release candidate at the customer site until the product is released. Is there any major changes coming up that are already known?
So far in the development we have had no big problems with releasecandidate.
