3. IBM Software Group | EGL Simplify Innovation IBM Software Group EGL – IBM’s Newest Business Language Problems that IBM i customers encounter Reality …  business and regulatory needs are highly dynamic  major investments in existing applications … they:  “run the business” and took years, sometimes decades, to build  are “stuck” in their current environment (green screens, etc…)  MUST be leveraged while advancing! … evolve or die Customers need …  a modern, “real” web user interface  Need latest “web 2.0” capabilities to compete, but the technology curve is very steep  Too hard to train new users in 5250 screens  “Screen scraping” is good, but is not adequate as a strategic solution  flexibility  Need to be able to deploy to other platforms as business needs change  Transition to a service-oriented architecture easily and quickly  New applications purchased on Linux, AIX, Windows…need to be able to integrate with them  to leverage existing skills  Used to high productivity with RPG and IBM i…don’t want to give that up  Need to leverage skills & knowledge of current developers most effectively for the future Applications TeamsPeople without … Taking 5 years Breaking the bank Incurring significant risk

4. IBM Software Group | EGL Simplify Innovation IBM Software Group EGL – IBM’s Newest Business Language Problems that IBM i customers encounter 1. Need a modern, “real” web user interface – Options 4 Pro’s: Easy to create/maintain “legacy” data entry folks have it all memorized Con’s: “The business” views as “out of touch” Can’t extend to web and specialized devices Hard to train new users Leave as Green Screen Pro’s: Quick ROI and Web UI Con’s: Maintenance activities take you back to DDS Don’t integrate well with new web applications “Screen Scrape” to achieve Web UI Pro’s: High quality results Con’s: Large work effort to achieve results Might require different developers for UI Re-factor RPG and build new web UI Pro’s: Result is true Web 2.0 UI … DDS goes away Quick results and high quality Refactor and enrich UI as desired Con’s: No Green screen alternative for those die hards… Migrate RPG/DSPF to EGL/EGL RUI

6. IBM Software Group | EGL Simplify Innovation IBM Software Group EGL – IBM’s Newest Business Language Problems that IBM i ISV’s and some customers encounter 3. Leverage Business-aware Developers for Web 2.0 RPG/COBOL developers … they know the business EGL … Leverage them for Web 2.0!

7. IBM Software Group | EGL Simplify Innovation IBM Software Group EGL – IBM’s Newest Business Language EGL Solution to these problems  EGL is a true cross-platform, cross-tier language targeted at all types of developers and applications  Traditional, procedural, object-oriented, Web, SOA, etc.  Web 2.0 built in  SOA built in  The goal of EGL is to shield developers from complexities that are unnecessary for building business applications.  EGL is an excellent target language for evolving existing, traditional applications in RPG, COBOL and many other languages Machine Code Assembly Language C++/C# COBOL EGLRPGJava PhP

8. IBM Software Group | EGL Simplify Innovation IBM Software Group EGL – IBM’s Newest Business Language 8  Build end-to-end Web 2.0 quickly with a single language  Fully extensible  Use a language that is easy to learn  Benefit from productive development  Use Ajax without any of its complexities  Use a rich, extensible widget library  Debug web applications in an Eclipse IDE  Consume any type of web service EGL Web 2.0 built in

9. IBM Software Group | EGL Simplify Innovation IBM Software Group EGL – IBM’s Newest Business Language EGL Web 2.0 in EGL is much more productive Google Maps API Example: Simple Geocoding <script src="http://maps.google.com/maps?file=api&v=2.x var map = null; var geocoder = null; function initialize() { if (GBrowserIsCompatible()) { map = new GMap2(document.getElementById("map_canvas")); map.setCenter(new GLatLng(37.4419, -122.1419), 13); geocoder = new GClientGeocoder(); } function showAddress(address) { if (geocoder) { geocoder.getLatLng( address, function(point) { map.setCenter(point, 13); var marker = new GMarker(point); map.addOverlay(marker); marker.openInfoWindowHtml(address); } ); } handler MyRuiHandler type RUIhandler { initialUI = [ addressForm, map ] } addressField TextField { text = "1600 Pennsylvania Ave, Washington DC", width = 250 }; goButton Button { text = "Go!", onClick ::= goButton_clicked }; addressForm Box { children = [ addressField, goButton ] }; map GoogleMap { width = "500px", height = "300px" }; function goButton_clicked (e Event in) addresses String[] = [ addressField.text ]; map.showAddresses(addresses, addresses); end HTML and JavaScriptEGL Rich UI All code, including UI and controller logic, is written completely in EGL. The complexity of the Google Map APIs are hidden from the developer, so the developer can focus on the actual business requirement and not technical complexities.

At development time…  Focus on the business logic  Implement SOA design elements: services and interfaces  Leverage existing business developers for new SOA development  Ignore deployment targets/technology while coding/testing Deploy EGL services… To any platform ( Java to WAS/Tomcat, COBOL to CICS, i5/OS )  As a Web service (uses SOAP)  As a private service (uses CICS ECI or TCP) Leverage external web services…  EGL Interfaces  represent external web services  are created via import from WSDL  allow the EGL developer to stay within the context of EGL programming
