EGL provides just the right balance of simplicity and flexibility, and enables application developers to focus on solving business problems rather than expending time and energy on technology. For example, Informix 4GL developers who are unfamiliar with Java can use EGL to quickly build data-driven Web applications and business logic. They can then write and debug their applications in EGL, and the Java code will be generated for them. So they can then build dynamic Web applications without having to learn the Java language. This provides significant advantages, enabling clients to minimize application development time and resource requirements. We give you an overview of EGL, its concepts and operations, and walk you through a step-by-step tutorial to develop an simple Web application. Included is an overview of the 4GL to EGL migration process and a sample application migration. You will be alerted to potential migration issues, and given the information to resolve them. We also include guidance for working with special database behavior and requirements, JasperReports, and a number of advanced EGL topics for developing robust and individualized applications. 410 0$aIBM redbooks. 606 $aDatabase management$xComputer programs 606 $aINFORMIX-4GL (Computer program language) 608 $aElectronic books. 615 0$aDatabase management$xComputer programs. 615 0$aINFORMIX-4GL (Computer program language) 700 $aBallard$b Chuck$0891886 701 $aDa Silva$b Vlaunir$0892142 701 $aFarrell$b Daniel M$0892143 701 $aKoerner$b Alexander$0892144 701 $aSayles$b Jonathan$0892145 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910449799403321 996 $aTransitioning$91992343 997 $aUNINA
