Data View source

A Data View source creates a connection to be used with IBM Operational Decision Management rules. For complex rules that use a hierarchical data model, note that administrators may restrict use of such rules because they can degrade performance. For details, see Locking data options.

A Data View node can be configured in IBM® SPSS® Modeler to include data in streams that was defined in an IBM SPSS Collaboration and Deployment Services analytic data view. An analytic data view defines a structure for accessing data that describes the entities used in predictive models and business rules. The view associates the data structure with physical data sources for the analysis.

For more information, see the IBM SPSS Modeler documentation and the Source, Process, and Output Nodes section of the IBM SPSS Modeler help.

When you select a Data View source, you are prompted to enter further details:

Analytic data source. Select the analytic data source from the repository.

Table name. Select the table from which data is to be used. This is a table from the data model in the analytic data view. Each table in the data model represents a concept or entity involved in the predictive analytic process. Fields for the tables correspond to attributes of the entities represented by the tables. For example, if you are analyzing customer orders, your data model could include a table for customers and a table for orders. The customers table might have fields for customer identifier, age, gender, marital status, and country of residence. The orders table might have fields for the order identifier, number of items in the order, total cost, and the identifier for the customer who placed the order. The customer identifier field could be used to associate the customers in the customers table with their orders in the orders table.

Data Access Plan. Select the data access plan from which data is to be used. A data access plan associates the data model tables in an analytic data view with physical data sources. An analytic data view typically contains multiple data access plans. When you change the data access plan in use, you change the data used by your project. For example, if the analytic data view contains a data access plan for training a model and a data access plan for testing a model, you can switch from training data to testing data by changing the data access plan in use.

Optional Attributes. If available and if desired, select optional attributes to add to the data source.
