Data set rules
Data sets define collections of records, allowing you to set up instances that make use of data abstraction to represent data stored in different sources and formats.
Depending on the data set type that you select when creating a new instance, data sets represent various types of data, such as data in database tables or decision data stores, or Visual Business Director (VBD) data sources.
Through the data management operations for each data set type, you can read, insert, and remove records. You can use data sets on their own through data management operations and as part of combined data streams in decision data flows.
Default data sets
In addition to the data sets that you define in your application, there are default data sets:
Default data sets
| Name | Class | Description |
| pxInteractionHistory | Data-pxStrategyResult | This data set represents Interaction History results. It is used to read and write the captured response information to the Interaction History data store through activities or data flows. |
| pxAdaptiveAnalytics | Data-pxStrategyResult | This data set represents adaptive inputs. It is used to update the adaptive data store through activities or data flows. |
| pxEventStore | Data-EventSummary | This data set is used to read and write events data that you create in the Event Catalog. It can store a number of events details (such as CustomerId, GroupId, CaptureTime, EventType, EventId, and Description) and reference details that are stored outside of this data set. |
Only one instance of each of these data sets exists in Pega Platform. You cannot create more instances or modify the existing one.
Where referenced
Data sets are referenced in data flows and, through the DataSet-Execute method, in activities.
Access
Use the Application Explorer or Records Explorer to access your application's data set instances.
Category
Data set instances are part of the Data Model category. A data set rule is an instance of the Rule-Decision-DataSet rule type.
- Data set rule types
Learn about the types of data set rules that you can create in Pega Platform. Your data set configuration depends on the data set type that you select.
- Data Set rules - Completing the Create, Save As, or Specialization form
Records can be created in various ways. You can add a new record to your application or copy an existing one. You can specialize existing rules by creating a copy in a specific ruleset, against a different class or (in some cases) with a set of circumstance definitions. You can copy data instances but they do not support specialization because they are not versioned.
- HDFS and HBase client and server versions supported by Pega Platform
Before you configure an HDFS data set or an HBase data set in Pega Platform, verify which combinations of the HDFS and HBase client and server versions your version of Pega Platform supports.
