RPG on the Move: Mobilize Your i
Choices and challenges in the world of mobile applications
Mobile applications are the hot topic of the day and your old RPG green-screen skills and tools are just not going to make the grade. In this session Paul discusses some of the factors you have to consider when embarking on the development of your first mobile applications.
Topics to be covered include:
- Design considerations for mobile - from F-keys to touch sensitivity
- Platform options - iPad? iPhone? Android? Blackberry? Tablets?
- Local processing or server/browser based?
- Can you do it with RPG? And what are your other language choices
Introduction to AJAX for RPG Programmers
AJAX provides a means of having a web page communicate with a server, either synchronously or asynchronously. Combined with CGI programming techniques (CGIDEV2 is used in the presentation), you now have a means of dealing interactively with a web page i.e. changing the contents of a web page without having to re-write the whole page.
And best of all, it is already installed on every PC, all you have to do is use it!.
In this session you will learn:
- The background to AJAX
- How it works
- Examples of how to use it
I Didn't Know You Could Do That With SQL
You have started to master SQL but you have a sneaky suspicion that there might be more to it.
In this session you will learn valuable and time saving techniques with SQL that let you avoid writing code. You will learn how to use SQL Subquery or Subselect in an SQL SELECT, INSERT, UPDATE, DELETE or CREATE TABLE statement to reference multiple tables without having to do a join of the tables involved. You will see how to use CASE and UNION statements, Common Table Expressions (CTEs) and where to use Full Outer Join and Hidden Time Stamp columns.
This session is based on the SQL function available in V5R4, V6R1, and V7R1 of OS/400 or i5/OS, assumes you have a basic understanding of relational database concepts and SQL.
Externalizing Database Processing in RPG IV
One of the major considerations for the ongoing modernization of applications is how to make functionality accessible to multiple interfaces. But no matter how the application interfaces may change (green screen, web, client server, mobile phones etc.) or how data may arrive on the system (FTP, EDI, XML etc.) you can be sure that all of the data is going to end up in a database.
Externalized database processing provides a means of encapsulating database access. This session discusses why you may want to externalize database processing in RPG IV and how to do it.
