EGL for web applications
Enterprise Generation Language (EGL) is a programming language that lets you write full-function web applications, using the IBM development environment Rational Business Developer (RBD). The complexity of Java and Java EE are 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 Java sources and classes, ready for deployment to a Java EE compliant server.
In this course, participants learn:
- to use the Enterprise Generation Language (EGL) development environment of IBM's Rational Business Developer (Extension) for web applications;
- to know and use the different definition elements of EGL by means of practical exercises;
- to structure and debug these applications efficiently;
- to prepare applications for the deployment process.
No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please let us know.
Application programmers who are going to develop web-based applications using EGL.
Participants should have a basic knowledge of Servlets and JavaServer Pages (see course Java EE: building web applications with servlets & JSPs). Also, a general knowledge of relational DBMS concepts (see course SQL and relational databases fundamentals) is advised.
