Adabas Natural Programming

This is a 5-day hands-on course that teaches programmers to design and code Natural Structured Mode programs interacting with Adabas databases.

Programmers requiring the ability to design and code in Natural will benefit from attending this course.

Delegates should ideally have some programming skills in another programming language.

The course provides all the information required to enable the students to design and code Natural Structured Mode programs that process data in an Adabas database.

The course includes detailed practical exercises.
