Pega 7 Platform: Live Data

Pega Live Data creates a data virtualization layer that separates the definition and use of data objects from the details of how and where data is stored and accessed.


Pega Live Data allows users to quickly and easily define the data required to build the apps they need, and then access that data in their running application, all without having to worry about how and where the data is actually stored and accessed. Pega Live Data does this by providing a data virtualization layer in your application, separating how your business apps use data from the plumbing, the technical details of how and when it's accessed. When you're building an application, you can easily define a data object that contains exactly the information you need, including all the fields you need. Once you define your business data objects, Live Data's virtualized data layer allows you to proceed with the development of your app and link in real data sources later. Developers can declare how data is mapped from existing data sources and services into your business data objects, and how the data is accessed and cached. They can import existing data definitions and define multiple data sources for each data object, allowing your application to have a single view of business data, even if that data is coming from multiple systems. External data sources are easily accessed using a variety of industry standard protocols, like MQ, SOAP and REST, and transformations can be defined and managed in the Live Data layer.

Pega Live Data allows you to easily access data in other systems without complicating your process flows with data calls or building inefficient systems that access data multiple times. Pega gives you an interactive way to visually design data structures and explore the relationships between your apps and the data types they use. At a glance, you can understand how data fits into your application and therefore, how to use and change it. Once you create a form that references your data objects, your user interface automatically responds to the data references you build in the Live Data layer, presenting dynamic screens that are automatically populated with data from your backend data sources, or reusing data it has in cache. Live Data can even predict and prefetch additional data that your process or decision logic will need later. And Live Data intelligently adapts to the context in which it's used, which means different parts of your business can reuse the same data objects, selecting the right data sources for each situation. Using Pega Live Data, you encapsulate a business view of data and insulate your applications from changes to underlying data sources. Your applications are free to evolve to meet the changing needs of your business. Our world is constantly changing. Only Pega lets you build for change.
