Data Mining Query Interfaces

Data mining queries are based on the Data Mining Extensions (DMX) language. You use DMX for all prediction and modeling tasks, including classification, risk analysis, generation of recommendations, and linear regression. You can also retrieve the patterns and statistics that were generated when you processed the model.

The syntax for a prediction query using DMX is similar to the syntax for a query in [!INCLUDEtsql]. Both [!INCLUDEssManStudioFull] and [!INCLUDEssBIDevStudioFull] provide tools that help you build DMX prediction queries.

This topic describes the interfaces that you can use to create and execute data mining queries using DMX.

Query Tools

Application Programming Interfaces

Data Mining Query Tools

[!INCLUDEssNoVersion] provides the following tools that you can use to build prediction queries, content queries, and data definition queries against data mining objects:

  • Prediction Query Builder

  • Query Editor

  • DMX templates

  • Integration Services data mining components

Prediction Query Builder

Prediction Query Builder is included in the Mining Model Prediction tab of Data Mining Designer, which is available in both [!INCLUDEssManStudioFull]and [!INCLUDEssBIDevStudioFull].

When you use the query builder, you can use graphical tools to select a mining model, add new case data, and add prediction functions. The Prediction Query Builder includes a text editor that you can use to modify the query manually, and a simple Results pane to view the results of the query.

Query Editor

The Query Editor in [!INCLUDEssManStudioFull] provides tools that you can use to build and run DMX queries. You can connect to an instance of SQL Server Analysis Services, and then select a database, mining structure columns, and a mining model. The Metadata Explorer contains a list of prediction functions that you can browse.

DMX Templates

[!INCLUDEssManStudioFull] provides interactive DMX query templates that you can use to build DMX queries. If you do not see the list of templates, click View on the toolbar, and select Template Explorer. To see all Analysis Services templates, including templates for DMX, MDX, and XMLA, click the cube icon.

To build a query using a template, you can drag the template into an open query window, or you can double-click the template to open a new connection and a new query pane.

For an example of how to create a prediction query from a template, see Create a Singleton Prediction Query from a Template.

Warning

The Data Mining Add-in for Microsoft Office Excel also contains a number of templates, along with an interactive query builder which can help you compose complex DMX statements. To use the templates, click Query, and click Advanced in the Data Mining Client.

Integration Services Data Mining Components

You can also include prediction queries as part of a [!INCLUDEssNoVersion] [!INCLUDEssISnoversion] package. The following tasks and transformations in [!INCLUDEssISnoversion] support the creation and execution of DMX prediction queries and DMX statements.

Component Description
Data Mining Query task Executes DMX queries and other DMX statements as part of a control flow.

The task editor provides the Prediction Query Builder, and a text box for modifying the DMX query manually. However, the task editor cannot validate the query against objects in an [!INCLUDEssASnoversion] solution. Therefore, it is best to create a query within [!INCLUDEssBIDevStudio] or [!INCLUDEssManStudio] and then paste the text of the statement or query into the task editor.
Data Mining Query transformation Executes a prediction query within a data flow, using data supplied by a data flow source.

The task editor provides the Prediction Query Builder, and a text box for modifying the DMX query manually.

The transformation can only be used for creating queries that use data in the data flow; that is, queries that use the PREDICTION JOIN syntax. This component cannot be used for executing content queries or other kinds of DMX statements.

Application Programming Interfaces

You can create custom applications that execute queries against data mining models by using a variety of programming languages, in combination with server protocols such as OLE DB or Analysis Services ADOMD client. For more information, see Data Mining Programming.

However, XMLA constitutes the underlying message format for all interactions with an Analysis Service server. Within an XMLA message, queries are represented differently depending on whether you are sending a prediction query based on DMX, a content query, or a query that retrieves model metadata using the data mining schema rowsets.
