The topmost application in this stack (layer cake) will always contain an Implementation structure, which means it will hold concrete classes that can store instances of data. This base application will be used as “next in line” for the proprietary rule resolution whenever pattern and directed inheritance within the application itself is exhausted. Every Pega application is built on exactly one other base application. We will however select Enterprise application from the get-go.Īpart from the application name and description, the most important selection is the Built on application. Also, Express could be a good starting point for Proof of Concept (PoC) programs to keep focus on creating tangible business value and leveraging Out of the Box (OOTB) features instead of these customizations.

One should not think lightly about naming class layers, since it could make or break maintainability and re-usability in the future. This wizard will effectively generate rules to define the Organizational and Class hierarchies. To capture these aspects Pega comes with a wizard called App Express. It also defines certain business and technical aspects. This structure includes more than just an application name. Now what? It´s time for one of the essential tasks often performed by a Lead System Architect (LSA) which is setting up a new application structure. So you have the Pega 7 platform up and running.
