Using Prodatasets

In this course, the student will learn how to identify when and where to use datasets
and then practice incorporating datasets into applications during hands-on exercises
using Progress Developer Studio for OpenEdge. The course emphasizes defining,
populating, and performing data operations using datasets and sharing data with
other applications. The course includes an overview how datasets are used in a
distributed architecture, how to control the behavior of datasets, and how read or write
dataset data as JSON data.

Application developers who want to incorporate modern, efficient data-handling in their applications.

After completing this course, you should be able to:
• Explain what a dataset is.

Write ABL code to:
• Define datasets.
• Populate a dataset in server-side code.
• Modify data in a dataset in client-side code.
• Apply changes to a dataset to the database in the server-side-code.
• Detect and handle dataset events.
• Detect and handle dataset errors.
• Read and write dataset data as JSON.
