Real-time event processing

Real-time event processing is a mechanism that can be used to analyze a high velocity stream of events entering the system and derive conclusions from them. It is possible to define metrics, measurements, and conditions under which subsequent trigger events are generated.

For details, see Real-time event processing.

End of support for form-based rule forms in Pega 7.1.9

Rule forms that are configured to render as forms are no longer supported in Designer Studio or end-user applications. Form-based configurations are found on custom rule types that were created in earlier versions of Pega 7 and are characterized by pop-up windows that are rendered externally from Designer Studio.

Reconfigure Pega 7 applications that use such rule forms by using standard harnesses and sections.

1. Open the class form.
2. Click the Advanced tab.
3. Select Harness from the Rule formmenu.
4. Create a new harness and new sections that implement the logic of the custom rule, using standard user interface layouts and controls.

Migrating custom rule forms to harnesses and sections offers the following benefits:

• User interfaces become HTML5 WC3 compatible and responsive to different screen sizes.
• User interfaces become cross-browser compatible, rendered consistently in Google Chrome, Mozilla Firefox, Apple Safari, and recent versions of Microsoft Internet Explorer.
• Rendering performance on modern browsers is dramatically improved.
• User interface pop-up behavior is eliminated; all windows are rendered inside Designer Studio and end-user applications.

Text analytics on the Pega 7 Platform

The Pega 7 Platform offers users the capability to analyze units of text, extract quality information, and translate it into business intelligence. The text analytics functionality aims to determine the positive, negative, and neutral polarities (tone) of subjective sentences. It also provides mechanisms for categorizing units of text and classifying text elements into predefined categories. You can use it to analyze text-based content including news feeds, emails, and postings on social media streams, such as Facebook, Twitter, and YouTube.

For more information, see Introduction to text analytics on the Pega 7 Platform.

Updates to the Data Flow rule

It is now possible to use report definitions as primary and secondary sources in the Data Flow rule. The data flows that are sourced by a report definition can be distributed on multiple nodes. When using a database table data set as the destination of the data flow, you need to select one of the save options for the data set (insert records or insert and update records).

Updates to the Event Strategy rule

When you design event strategies, you can use the Filter shape for basic arithmetic and text expressions. You can also specify start conditions for the tumbling and sliding windows.

Updates to the Predictive Model rule form

The Predictive Model rule form provides the XML schema preview for uploaded PMML models. You can use this preview to view the structure of a model and to correct errors before saving the rule. When the model contains errors, they are displayed in the Errors section at the bottom of the rule.

Updates to the Strategy rule

The Strategy tab of the Strategy rule form contains a new Test runs panel from which you can run simulations and test strategies for single and multiple customers. When you test strategies for multiple customers, you can identify the most popular propositions offered to the customers, check the overall strategy performance, and examine the performance of the individual components.

Pega 7 Express is available on-premises

You can now experience Pega 7 Express by switching your enterprise application from Designer Studio to express mode. By default, users with access to the Developer portal can switch between these two development environments. You can also create an express application to work in express mode exclusively.

Trial versions of Pega 7 Express continue to be available on the cloud. To view the documentation for both the cloud and on-premises environments, see Getting started with Pega 7 Express.

Access to Pega 7 Express from within Designer Studio is not supported on mobile devices.

Context-specific documentation is not available in express mode

Help topics that are opened from express mode display content that is specific to Designer Studio.

If your system is dedicated to applications that are developed in express mode exclusively, and you do not need Designer Studio help topics, you can set the Online Help URL field on the System Settings landing page to: https://pdn.pega.com/sites/default/files/help_p7e/procomhelpmain.htm. Alternatively, you can view the contextual help system for Pega 7 Express in a separate browser tab.

Design-time limitations in express mode

Some limitations apply when you develop an enterprise application in express mode. At design time, some features are disabled or have limited options when you configure them in Designer Studio and switch to express mode. The use of these features does not restrict the run-time behavior of your application; however, you cannot change the configuration of these features unless you switch from express mode to Designer Studio.

For more information about each limitation and the recommended action to take, see the following information:

• Pega 7.2.2 Design-time limitations in express mode
• Pega 7.2.1 Design-time limitations in express mode
• Pega 7.2 Design-time limitations in express mode
• Pega 7.1.9 Design-time limitations in express mode
