Enterprise Generation Language for Server Applications


Enterprise Generation Language (EGL), in IBM's WebSphere Developer for zSeries or Rational Application Developer, is a development environment and programming language that lets you write full-function server applications for batch or online environments. The complexity of screen interaction or data access is hidden so that the focus lies on the business problem rather than on software technologies. After coding the EGL program, a generation step leads to the creation of COBOL (or Java) sources, that can be prepared to produce executable objects, ready to deploy on the server (UNIX, iSeries or z/OS mainframe).

This course is available for one-company, on-site presentations.

Objectives

On successful completion of this course you will be able to:

  • use the Enterprise Generation Language of RAD/WD4Z for server applications (batch or text user interface
  • use the different definition elements of the Enterprise Generation Language by means of practical exercises
  • structure and debug these applications efficiently
  • prepare applications for the generation process.

Who Should Attend

Application programmers who are going to develop traditional text user interfaces (3270) and/or server applications using the Enterprise Generation Language.

Prerequisites

Experience with traditional mainframe applications in a CICS or IMS/TM environment. Also, some general knowledge of the relational DBMS concepts is advised.
