18 RPG Open Access (OA)

19 5250 vs Open Access 19

20 What is RPG Open Access Developed by IBM Get data from RPG to browser Green screens or new RPG programs Bypass 5250 datastream Handler populates data structure Uses traditional I/O, existing RPG skillset 20

21 RPG OA - Requirements Requires source code Add 1 line of source code and recompile RPG IV only Field data only Conditionally compile if green screen required Grid uses load all subfile Minimum OS IBM i

25 PHP

26 Stateless Web Applications New web application development No call stack Standard or other platforms Scalable Customer facing SEO Bookmarks 26

27 Why is PHP Attractive? PHP is a proven enterprise solution Thousands of IBM i shops using PHP Easy to adopt for RPG developers Procedural to OO to frameworks Similar to RPG subprocedures Attract new developers 5-7 million PHP developers, coming to platform Community Free scripts, support from IBM, Zend and vendors Source: stackoverflow.com 27

28 Why PHP? 28

29 Leverage RPG Code 29

30 PHP RPG Program Call 30

31 Node.js

32 What is Node.js Server side web applications JavaScript for the server and client side Open source Created 2009 Popular technology Walmart, LinkedIn, PayPal 32

33 Benefits of Node.js Performance Open source community Attract new developers One less language Programmer productivity Leverage RPG 33

34 ILE RPG CGI

35 ILE RPG CGI WebSmart ILE, CGIDev2 Stateless Uses native CGI APIs Runs in standard Apache web server Produce secure web applications Login IBM i user ids, LDAP, etc Session management Better than stateful for new, highly scalable apps SEO, Bookmarks 35

36 Mobile

37 4 Approaches to Mobile Development Native mobile applications Mobile web applications Hybrid applications And the new best practice Responsive 37

38 Native Mobile Applications Device s native programming language ios Objective C/Swift Android Java Windows C# Not cross platform, ecosystem specific App Store, Google Play Store, Windows Store 38

39 Native Mobile Applications Access to device s hardware Great user experience Speed Reliability Access Web services for IBM i data 39

40 Mobile Web Applications Website accessed from device browsers HTML, CSS and JavaScript PHP, RPG,.NET and more Looks more like a native application 40

41 Mobile Web Applications Single code base for all platforms Not all browsers are the same Optimize for specific browsers Responsive stay tuned HTML5 and JavaScript frameworks jquery, BootStrap, Angular Instant deployment 41

42 Mobile Web Applications Offline support Less access to device hardware Performance dependencies Network Device 42

43 Hybrid Mobile Applications Use web technologies Turn web application into native mobile app Platform specific wrappers Run in native container App Store, Google Play Store, Windows Store APIs to access device hardware No native language, reusability of code Easier to enter app world Slower performance 43

44 Responsive Web Applications No longer just a trend, a best practice One codebase serves desktop to phone Responsive frameworks available BootStrap is the most popular Logic can be PHP, Node.js, ILE etc. HTML5 keeps improving and improving access to device hardware 44
