Data Analytics And Visualization - Heat Maps
Feb 25, 2008Hey gang,
Do any of you know if it is possible to do a heat map chart with reporting services or with the new dundas capability coming in SQL Server 2008?
Thanks in advance.

Hello,
I'm working on a distributed application which requires data from a central database to be shown to various users. In particular users should be able to open "views" on the database, specifying the data they are interested in, and being shown the result.
This can be easily accomplished modeling the view specifications as SQL select queries, sending those queries to the server, and visualizing the result. This approach is very flexible, supported, fast and definitely the way we would like to implement it.
The problem is that we have an additional requirement.
In general the data the users might be interested in is not static, and when that data changes, those changes should be propagated to the client views.
There are lots of solutions and technologies aimed to solve very similar problems, but no one seems to support this scenario well.
1. You can re-run the queries every x time (polling)... but this is hardly an option when you have hundreds of client-views that require data to be updated in real-time (so "x time" should be, say, 1 second).
2. You can use query notification... but the documentation explicitily says it doesn't scale well and shouldn't be used with a large number of clients (which is exactly what is needed in this case).
3. You can use replication services... but this technology doesn't really seem to be created to support this scenario.
4. You can use notification services... but even this technology seems to be focused on different scenarios. I haven't looked at it extensively anyway.
5. You can use DML triggers to track data changes... but you still don't have the publish-subscribe mechanism to register client views and the mechanism to know which client views are affected by the changes.
6. You can implement a business logic tier that relates modification requests to client views... and basically do everything from scratch without using existing services.
What are your opinions?
Thank you,

Hi
How can I visualize Microsoft Time Series prediction chart for web users? (for Internet Explorer browser)
Is there a way to do it using Reporting Services or special web controls?
I hoped Data Mining Web Controls helped me but they didn't support Microsoft Time Series.
-------------------------
Supported Algorithms
At this time, Data Mining Web Controls include the following:
- DMClusterViewer €“ For the Microsoft_Clustering algorithm.
- DMDecisionTreeViewer €“ For the Microsoft_Decision_Trees algorithm.
- DMNaiveBayesViewer €“ For the Microsoft_Naive_Bayes algorithm.
Models using other algorithms cannot be displayed with the Web controls.

Is there a way to visualize Microsoft Time Series in browser ?
When will there be such facility?

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,
Yours sincerely,
After testing out the application i write on the local pc. I deploy it to the webserver to test it out. I get this error.
System.Data.SqlClient.SqlException: The conversion of a char data type to a
datetime data type resulted in an out-of-range datetime value.
Notes: all pages that have this error either has a repeater or datagrid which load data when page loading.
At first I thought the problem is with the date, but then I can see
that some other pages that has datagrid ( that has a date field) work
just fine.
anyone having this problem before?? hopefully you guys can help.
Thanks,
I have used both data readers and data adapters(with datasets) in the projects that I have worked on. I am trying to get some clarification on when I should be using which one. I think I am doing this correctly but I want to be sure I am developing good habits.
As the name might suggest, it seems like a datareader is for only reading data. I have read that the data adapter and dataset are for a disconnected architecture. Or, that they can be used for this type of set up. I have been using the data adapter and datasets when writing to a database and the datareader when reading from a database.
Is this how these should be used? Is the data reader the best choice for reading data? Am I doing this the optimal way from a performance stand point?

View 7 Replies View RelatedI 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?

I setup this package to import data from a Sharepoint list to a SQL Server data table. The primary key of my SQL table is mapped to the Title column of my Sharepoint list. There is a possibility that duplicate values will be entered in the Title field of the Sharepoint list. So when importing data into my table via SSIS, my package always error-out when there it comes across duplicate values. how you others have managed data integrity when importing from a Sharepoint list with the Title column being mapped to the primary key of a table.
View 4 Replies View RelatedHello,
I am wondering what conversion rules apply, when a string, which contains a number, is saved to a SQL Server 2005 into a column of type decimal.
This is the code I€™m using (C++):
CString cValue = "0.75"
_variant_t vtFieldValue;
vtFieldValue = _variant_t(cValue)
pRecordSet->Fields->Item["MyColumn"]->Value = vtFieldValue;
"pRecordSet" is an ADO recordset. The database column "MyColumn" is of type "decimal(19,10)".
The most important question for me is, if the regional settings of the database server or the regional settings of the client PC are considered during the conversion from the string to the decimal value. For example in standard French regional settings the "." would not be recognized as decimal separator.
I am also wondering if the language of the database instance, in which this data is saved, is considered during this conversion or any other settings of this database instance.
So my general question is: Does anybody know exactly what rules apply during the above mentioned conversion?
Thank you for your help.

I've question about how to handle structural datamodel changes in a datasource of PowerPivot. Suppose I'm developing a starmodel in SQL Server and sometimes a datatype changes or a name of a field changes in a table. It seems to me that PowerPivot handle this not gracefully as Analysis MD does (mostly). I received an error because of a wrong fieldname or even no error when a dattype changes in PowerPivot. Is this common or do I something wrong here. Does this mean that every time the datamodel changes the PowerPivot should be recreated? Or am I missing the clue here?
View 6 Replies View RelatedHi everyone,
I have to extract, dayly a list of contacts on a exchange server in a table on our EDW on sql server 2005. Is it possible to get the information directly from a dataflow or i will have to developpe a script task ?
Need help desperatly !!!
I am getting ErrorCode 8 while loading the data from stage to model. I have checked my error view it states that "Member Code is Inactive".
Initially I have loaded same set of data in Model from MDS Stage table but then deleted with ImportType = 5 which removed all the data from the MDM model.
Now i want to load it back but its giving the Error Code 8 .. Before loading the same data i have changed the stage table Importtype to 2 and Importstatusid to 0.
Hello,
I have noticed that for one of my data-flows, the process is really long during the phase "the final commit data insertion has started".
To be accurate, the process is fast until it reaches this phase. It happens often when I load millions of lines.
The extraction is done from a database SQL Server 2005 to a database SQL Server 2005, on the same server (with the SQL Server native provider).
I used a SQL Server destination but I have tried with an OLE DB destination and it is the same situation.
Why the process could be so long during this phase?
There is a way to optimised my package to avoid that?
Any idea is welcome.
Thanks.

View 3 Replies View RelatedI think I am definitely thrashing and am not getting anywhere on something I think should be pretty simple to accomplish: I need to pull the total amounts for compartments with different products which are under the same manifest and the same document number conditionally based on if the document types are "Starting" or "Ending" but the values come from the "Adjust" records.
So here is the DDL, sample data, and the ideal return rows
CREATE TABLE #InvLogData
(
Id BIGINT, --is actually an identity column
Manifest_Id BIGINT,
Doc_Num BIGINT,
Doc_Type CHAR(1), -- S = Starting, E = Ending, A = Adjust
Compart_Id TINYINT,

I have tried a combination of the below statements but I keep coming back to not being able to actually grab the correct rows.
SELECT DISTINCT(column X)
FROM #InvLogData
GROUP BY X
HAVING COUNT(DISTINCT X) > 1
One further minor problem: I need to make this a set-based solution. This table grows by a couple hundred thousand rows a week, a co-worker suggested using a <shudder/> cursor to do the work but it would never be performant.
Was wondering if there was a best practice minimum permissions for creating a SQL login to use when setting up a new shared Data source for SSRS report manager?

Hello all. Before my arrival at my current employer, our consultantsphysically set up our MSSQL 7 server as follows:drive c: contains the mssql enginedrive d: contains the transaction logdrive e: contains the data filesNo filegroups were set up and the data files consist of only 1 largephysical file. Currently, our data file is >10GB. When I was trained onthe physical aspects of sqlserver, I was told to never create physical files[color=blue]> 2048MB each. If I did, I could expect inefficient physical storage of[/color]data and slower performance (due to the OS).Our server has 2 RAID-5 arrays. Drive c: and e: are located on the firstarray and drive d: on the second. We're running Windows 4.0 NT Server SP6with NTFS.Can someone comment on the use of 1 single large data file vs. more smallerdata files?
