IBM Rational Business Developer

IBM Rational Business Developer delivers the latest technology tools to support the definition and test/debug of EGL applications and services. It is also a generation engine that transforms the EGL source into Java or COBOL code optimized for deployment to a broad variety of application hosting environments, including Java 2 Platform Enterprise Edition (J2EE) servers, WebSphere, Apache, Tomcat, i5OS Integrated Application Server and others, as well as traditional transactional systems such as i5OS.

EGL hides the details of the target execution platforms and associated middleware, freeing a developer to focus on the business problem rather then on the underlying implementation technologies. Developers with little or no experience with Java and Web Technologies, can use EGL to create enterprise-class services and applications quickly and easily. Even those with little or no experience with i5/OS programming, can quickly create highly optimized System i Web services and programs.

IBM Rational Business Developer has functions that further strengthen the platform coverage, the support for SOA and for business integration solutions, the usability and versatility of the EGL language. It provides capability for extending RPG and COBOL applications to the Web.

IBM Rational Rational Business Developer address the full spectrum of modern business application requirements including the development of:

Business services: The EGL language includes the built-in notion of "service", allowing a developer to create and consume services in simple and straightforward way, and to permeate systems architecture with service orientation.
Web applications: Tight integration of EGL with the Java Server Faces (JSF) framework and JSF tools enable a developer to create Web applications in a simple and productive way, without the need to know Java or the details of the JSF framework.
Portlets: EGL JSF Web applications can also be deployed to WebSphere Portal Server. EGL provides built-in functions to interface the Portal framework, including support for inter-portlet communications.
Reports: EGL integration with BIRT, an open source reporting engine, allows for creation of sophisticated reports.
Batch systems: The language includes the built-in notion of a "batch program," which can be generated to run without end user interaction (for example, to produce reports or to batch database load and up-date.)
Text user-interface applications: To facilitate migration of legacy systems to a modern development environment, EGL includes the ability to create traditional 5250 character-based user interfaces and related programming constructs.
Tight integration of EGL and RPG/COBOL applications: RPG/COBOL applications can be easily extended to the Web.

IBM Rational Business Developer V7.1 delivers the following enhancements in addition to the existing capabilities of IBM Rational Business Developer Extension V7.0:

Support for MQ Series: Message queues can now be accessed using EGL language abstractions.
i5/OS Integrated Application Server support: Generated Java Web applications can now be deployed to the i5/OS Integrated Application Server.
i5/OS Data Queues and Data Areas support: These resources can now be accessed through the use of new EGL functions.
CVS files support: Comma separated value (CSV) files can now be accessed using EGL language abstractions.
Text User Interface applications: Language elements and tools allow a developer to write traditional 5250 character-based user interface programs.
Web transaction support: To facilitate migration of VisualAge Generator Web applications, EGL now supports the development and generation of applications using the VisualAge Generator Web Transaction feature.
BIRT integration: EGL integration with BIRT, an open source reporting engine, enables creation of sophisticated reports.
Portlets support: EGL JavaServer Faces (JSF) Web applications can be deployed to WebSphere Portal Server, and EGL provides built-in functions to interface the portal framework, including support for inter-portlet communications.
Enhanced security: EGL applications can include user sign-on capability to restrict access to resources only to authorized users, through new EGL support for access to JNDI/LDAP directory data and enablement of both container-managed and application-managed security.
JSF support enhancements: IBM Rational Business Developer V7.1 includes several JSF editor usability enhancements, the use of JSF AJAX-enabled type-ahead fields, and the use of LDAP security JSF support.
EGL language enhancements: These include the use of exclusive OR (XOR) operator, the ability to pass and return EGL records on function invocations and other minor enhancements.
EGL invocation from native Java: IBM Rational Business Developer generates Java wrappers that enables EGL invocation from native Java.
ILE service procedures invocation: EGL can invoke native i5/OS Integrated Language Environment (ILE) service procedures.
Usability enhancements: A new project wizard and numerous source editor and debugger improvements (such as automated formatting, improved content assist, dynamic error markers, code refactoring, ?jump to line" during debugging, dynamic code modification during debugging) significantly simplify the EGL development experience.
Built-in tools: for automated conversion of VisualAge Generator code to EGL.
Bi-directional text enhancements: A number of enhancements enable development and deployment of applications that require bi-directional text support.

IBM Rational Business Developer empowers programmers to increase their productivity when developing i5/OS application development through:

Abstraction: EGL provides concise and powerful notations that help to eliminate the tight coupling. It reduces the amount of coding required to interface systems and middleware. This abstraction simplifies and speeds up your development work.
Declarative programming: EGL includes a certain level of declarative specifications to help reduce repetitive and error-prone coding.
Language: EGL is an easy-to-learn language, comprehensive language. Modern, modular, and readable, it has a rich library of built-in functions to boost developer productivity for commonly required operations, such as date and time math, string manipulation, and so on. The language is extensible and offers full interoperability with other languages, including EGL interfaces to native Java, and seamless invocation of RPG or COBOL programs or any ILE procedure.
Tools: IBM Rational Business Developer contains a rich set of Eclipse-based capabilities, including EGL source level debugging, powerful smart editing, visual construction, graphical navigation, and automated generation of Create/Read/Update/Delete (CRUD) applications from Unified Modeling Language (UML) models or from data schemas.
SOA: EGL is designed to facilitate services development and deployment. A simplified SOA development paradigm is built into the language itself and complemented with the tools. EGL supports the creation of services without the need to know Web service protocols and standards such as Web Services Description Language (WSDL), Simple Object Access Protocol (SOAP), or Extensible Markup Language (XML).
