PowerBuilder Classic and PowerBuilder .NET can use OData datasources.
OData (the Open Data Protocol) is a Web protocol for querying and updating data that provides a way to unlock your data and free it from silos that exist in applications. OData is based on REST (Representational State Transfer). It uses the standard HTTP protocol to access data using GET, PUT, POST, and DELETE.
Create 64-bit native applications in PowerBuilder Classic.
In PowerBuilder Classic, you can set docking behaviors for the sheets that open in the MDI (multiple document interface) frame window.
You can migrate a PowerBuilder application from any version of PowerBuilder directly to PowerBuilder Classic. You cannot migrate applications from PowerBuilder .NET to PowerBuilder Classic, or from PowerBuilder Classic to older versions of PowerBuilder. Migrate older applications to PowerBuilder Classic before you port them to PowerBuilder .NET.
