Question to the PB Community:

We have a monolithic application consisting of a PowerBuilder frontend and C# .NET application server, both of which are tied to a MS SQL Server database. When the application was first written it was strictly PB, but over the years the app server was created, and much of the business logic and automated/background processing has been moved to it. However, the PB frontend still utilizes almost 300 windows and approximately 1500 datawindow/datastore objects (about a 3rd of which are for reports).

We have been tasked with moving all direct database connection from the PB client to the .NET app server. This means all 1500+ datawindow objects need to change how they retrieve and update their data so that they no longer establish a direct connection to the database. We had hoped to possibly leverage the webservice datawindow feature, but that has been deprecated and is now obsolete.

Can anyone recommend a course of action that would allow us to continue to use the datawindow objects in place within the client frontend application but move the corresponding CRUD functionality to our C# app server or some other centralized backend process? What would be considered the “best practice” for this scenario?

Thank you in advance for any advice.
