Using Cube Views As A Data Source To Build Mining Model
Nov 16, 2006
Hi all,
I am new to SQL Server 2005 Analysis Services and would like to use the OLAP Cubes as a datasource to build Mining Model . However i would like to use a particular view of the OLAP cube that i have generated to be used as the datasource for the mining model . I find that i am not able to save the Cube View while browsing the OLAP cube in Business Intelligence Studio. Is there a way i can acheive this requirement.
Any ideas regarding this will be really appreciated.
HI Thanks a lot for your answer I say my request but I don€™t know why anybody don€™t answer me I have a project about predicting a value about selling and buying of a good like t-shirts and I use data mining for my project ,so I should use time series algorithm ,that €˜s mean I have previous data about t-shirts for 11 months ago and now I should say for 12th month ,how many t-shirts are sale? My tables saved on the excel file and it is problem, because how should I use this table for building model? After building a model and structure and predicting the value of 12th month for this store in the mining model then I use this query in model in bi: €œSELECT PredictTimeSeries(amount) From [Forecasting]€? This query showed a column and prediction value. After all of that now I should show this value in the application so I use c# language for building it, so I use a form in c# then I add a button to form that with clicking on this button, I can connect to my structure and then show process of connecting in the panel, then with clicking on the other button I can use this query (€œSELECT PredictTimeSeries(amount) From [Forecasting]€? ) and after using I can see prediction value in the textbox, that€˜s mean the value of 12th month show on textbox. Form has two buttons: one button is for connecting to mining structure and other button is for sending PredictTimeSeries query to structure, one textbox, which is for showing the predicting value for 12th month for selling t-shirts, one panel for viewing the lift chart. Also you say You are building an application that programmatically creates mining structure and a model, and then you want to train the model and display some results. And I don€™t know how can I train my model, I should use a special code for it? If your answer is say, please explain that and then say that codes are for training. Please if you can send c# code for Sporadic of stage, please send that, I need to this code; my request is emergency for me. Thanks a lot i am very sad because any body don't answer me
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?
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?
I get the following error when I try to load the mining model in the mining model viewer
Query (1, 6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[NeuralNet].[GetAttributeValues]' function does not exist.
I get a similar error when I try to load the Load Mining Accuracy Chart
Failed to execute the query due to the following error:
Query (1, 6) The '[System].[Microsoft].[AnalysisServices].[System].[DataMining].[AllOther].[GenerateLiftTableUsingDatasource]' function does not exist.
This may be a noob question... but I am not able to create a data model and its frustrating me. :)
I made the Data Source... I made the Data Source View (just grabbed a table) and made the report model... but the model is empty >< When it autogenerated the model, it did yell at me about the table not having a primary key... do all the tables have to have primary keys???
I'm defining a mining structure against an OLAP dimension. The continuous value that I'm using both as input and for forecasting represents the time to complete a certain process.
There's something that strikes me as if it could be a problem, but I'm not sure. Our fact table has multiple columns (with multiple correponding measures in the cube). The "time-to-complete" measure is only populated on some of the fact rows - the rows that represent completion information. Other rows represent other information, and the "time-to-complete" value is set to 0. This works fine for cumulative time-to-complete and average time-to-complete, but it seems like it could mess up data mining. Will those 0-value facts skew the mining results? I'm not seeing a way to filter out those entries and only include the non-zero facts in the mining processing.
Or perhaps I'm totally misunderstanding something, which is quite possible. :)
I'm going through a very tedious process of documenting tables and fields for a third party database, with an eye toward creating lots of SSRS Reports. I'm making progress, but I was wondering if there's a slick way to export all the tables, fields and key relationships.
We have a set of cubes and dimensions, and we're experimenting with data mining against the cubes (primarily for forecasting applications). We have a custom time dimension (which we call calendar), not generated by the BIStudio wizard. The dimension has year/month/day/hour/... attributes. But when I try to add this Calendar dimension to the mining structure as a nested table using BI studio, it only shows the Year attribute, not the others. Other dimensions seem to show all the attributes.
Is there something we've done wrong in defining our time dimension? What determines which attributes show up as available for selection in BI studio?
I am trying to write some DMX queries to create and populate a mining model as a SSMS analysis services project. I followed the following steps:
1. Create the mining model using a CREATE MINING MODEL ... query.
2. Followed by the - INSERT INTO MINING MODEL ... query, which fetches prediction data from another mining model to populate the mining model.
3. I now want to use this new model for prediction, which requires processing the mining model first. When I process the model, it throws the following error:
Error (Data mining): The 'XYZ_Structure' structure does not contain bindings to data (or contains bindings that are not valid) and cannot be processed.
Please suggest if I am making a mistake in the above procedure. I will appreciate all help in overcoming this issue.
Auxilliary question: How do I process the mining model programmatically?
I tried to find the graphs I saved from Data Mining Model Viewer, but where is it saved? As we see from the mining model viewer we could save the graphs there by clicking the 'save graph' button, but where is the graph?
Really need help for that.
Thank you very much in advance for any guidance and help for that.
I would like to develop an application that can create Data Mining structures and a mining model in SQL Server 2005 with VB.NET. I tried the code from book Data Mining with SQL server 2005 in chapter 14 but did not work. Any good idea?
Thank you very much for your help. The errors that I can see in the code that you gave in your answer are the following and they are more or less the same as I had previously
I tried the code but initially I have encounter the following problems.
1. In any line that have the declaration As Server, As Database like in Public Function CreateDatabase(ByVal srv As Server, ByVal databaseName As String) As Database gives me the problem that type Database is not declared the same type Server is not declared and it does not give me any option.
2. In addition to that for As DataSource, As RelationalDataSource, As RelationalDataSourceView, As ScalarMiningStructureColumn, As DataSourceViewBinding, gives me the problem that type is not declared.
3. Finally in mc = New MiningModelColumn("Yearly income", Utils.GetSyntacticallyValidID("Yearly income", Type.GetType(MiningModelColumn))) is not accesible in this context because it is 'Private'. I have some more problems but I thing that by solving the above that I referred I will solve the rest.
We've successfully processed a large decision tree model in SQL Server 2005. When I try to view the tree in the mining model viewer, I get the following error:
TITLE: Microsoft Visual Studio ------------------------------
The tree graph cannot be created because of the following error:
'Exception of type 'System.OutOfMemoryException' was thrown.'.
For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft%u00ae+Visual+Studio%u00ae+2005&ProdVer=8.0.50727.42&EvtSrc=Microsoft.AnalysisServices.Viewers.SR&EvtID=ErrorCreateGraphFailed&LinkId=20476
The link provides no other documentaiton on the error.
We're using 64-bit SQL on a Dell Workstation running XP-64 with 16GB of memory. From my view of things we aren't close to running out of memory. Since the model processed and the error occurs when viewing the model, is this a problem with Visual Studio and nont necessarily Anlaysis Services?
I can't figure out how to put nested tables into the Data Mining Model Training Transform (SSIS). I can do a simple case table, but how do you get those nested tables with DM Training Transformation? Any ideas? Samples?
I dont think we should sample any nested tables for data mining model training? Since I think any nested tables are bound to the case table. Therefore whenever we sample the case table, the nested tables are like any other input attributes within the case table to be rectrieved as inputs accordingly?
Thank you very much for any guidance to clear my confusion.
I've created a Cluster data mining model and seems to correctly return data. However I've created a data mining dimension and cube but when I go to query the cube it doesn't return any data if I select any members on the data mining dimension. Any suggestions to where I can look to resolve this?
I've got a report that is using a cube as a data source and I can't get the report to show all the data. Only data at the lowest level of the cube is displayed. The problem is that most of the data I'm concerned with is at higher levels. There's no problem with the MDX. I get the correct results when I run the query.
I'm using a table to show the results. I've also tried a matrix, but I get the same results. I'm using SSRS 2005 and SSAS 2000.
Anyone have experience with this? Am I missing something simple?
I am attempting to create the "Classification - Children at Home" Data Mining Model as described in Larson's book. Each time that I create it.. ONLY the ALL LEVEL is shown and it is impossible to expand the model to look at the Decision Tree, Neural Network, or the Clustering model etc. Drill down is enabled (tried it with and without enabling the drill down). The Children at Home field has been populated with values from 0 - 4. Any ideas would be greatly appreciated. regards Steve

We had existing cubes in our Analysis Server, we were required to move them on another Reporting Server which would be using Data Replicated every night to that server. Problem is now source data is divided into 2 Reporting Database Servers. Table Names/View Names are the same in all the Databases. I just want to change the data source pointing to existing Database to the new Reporting Server. Can you tell me how this can be achieved?
I got a quite a strange problem with Mining structure for OLAP data source though. The problem is: I am not able to edit the mining structure in the mining structure editor. The whole data source view within the mining structure editor is greyed. Could please anyone here give me any advices for that?
Thank you very much in advance for any help for that.
What do you use to check the data structure at a source database? For instance, i've got a database which i can connect to using the ODBC (ado.net) connection in SSIS. To get a better understanding on the data and the relationships in the tables i would like to get a database diagram (ERD) of the source DB. Also i would like to be able to import this diagram into SQL server in the database diagram section when i'm going to load this data into a DWH. Any tips or free tools on better understanding the structure of an external source DB?
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?
Hi, I am not getting Mining Accuracy Chart and Min ing Model Prediction Plz tel me how to do.And how to use the filter input data used to generate the lift chart and select predictable mining model columns to show in the lift chart
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.
When I attempt to generate a datasource model I get the following error messages: ------------------------------------------------ More than one item in the Entity 'Customer' has the name 'Customer Merge Custs'. Item names must be unique among immediate siblings. (DuplicateItemName)
More than one Field in the Entity 'Customer' has the name 'Customer Merge Custs'. Field names must be unique within an Entity. (DuplicateFieldName)
More than one item in the Entity 'Pricing Service Layout Detail' has the name 'Pricing Service Extensions'. Item names must be unique among immediate siblings. (DuplicateItemName)
More than one Field in the Entity 'Pricing Service Layout Detail' has the name 'Pricing Service Extensions'. Field names must be unique within an Entity. (DuplicateFieldName) ---------------------------------------------------
Examining any of the above tables in SQL Server Management Studio does not reveal any duplicate column names. In fact, 'Customer_Merge_Custs' does not appear to be a column in 'Customer' nor does 'Pricing_Service_Extensions' appear in 'Pricing_Service_Layout_Detail'.
As an experiment, deleting the table 'Pricing_Service_Extensions' and regenerating did make the two associated messages go away.
I've used the Dec CTP of SQL 2005 SP2 to create a Report Server Project.
In this project, I can create an XML datasource and successfully use that datasource in a report published on Sharepoint using the new Sharepoint AddIn.
I've also used Dec CTP of SQL 2005 SP2 to create a Report Model Project.
In this project I can create SQL Data Sources, DataSource Views andReport Models which I deploy to sharepoint and create a report builder based report from.
What I can't do is create an XML based datasource in a Report Model Project. Also, if I create one solution containing both types of project, the Report Model Project Data Source Wizard suggests I can create a data source based on an existing data source in my solution. What I find is that my XML data source from the Report Server Project is not listed. In fact even if I create a SQL data source in the Report Server Project that isn't available either.
