This free online course is for experienced ABL Developers who are responsible for creating the server-side business logic for an OpenEdge ABL application.

Product Version: Progress OpenEdge 11.6.SP3    Duration: Equivalent to 4 hours of instructor-led training

Course Description

Progress OpenEdge Data Object Services provide client access to the data for an OpenEdge ABL application. The business logic part of the application includes the application’s Business Entity classes whose instances run in an application server and provide data for the Data Object Services. In this course, you will learn the requirements for developing a Business Entity and how the methods of a Business Entity are used to provide CRUD and submit access to the application data. First, you will create business entities using the New Business Entity wizard in Developer Studio. Then you will learn how you can customize generated code for your application.
