As an IBM i developer looking to start building IBM i-based web and mobile apps for your users, there are many possible paths to take. But which direction is best for you and your company?
On your quest to deliver applications with a modern GUI, you could simply “screen scrape” your way there, retaining those tried-and-true green screen underpinnings with a browser overlay. Results tend to be clunky, but it’s relatively quick and easy.
Or you could take the CGIDEV2 API approach and hammer your way through an “old school” method for serving up web pages loaded with lots of HTML from the back-end.
Or you could pick one of many third party solutions that let you “wizard” your way to building an IBM i-based web or mobile app.
So to break it all down, here are the top five reasons why Valence is your best solution for developing web and mobile apps on IBM i:
State-of-the-art HTML5-based user interface
Valence uses the robust Ext JS framework for desktop web apps and the Sencha Touch framework for mobile apps. These tools give Valence apps a state-of-the-art, “rich” user interface, on par with the very best websites you can find on the Internet. When users see Valence apps running in their browsers they quickly come to love the modern look and feel. The rich interface isn’t just for show either. The ability to dynamically sort columns, drag and drop elements, perform advanced search, show charts and graphs, etc., are highly useful and intuitive functions for your users. And as web technology continues to advance, these types of features are coming to be expected in any competitive company’s internal and external websites.
Valence uses a true “Web 2.0” architecture
Many of our competitor systems encourage IBM i developers to create web pages built over a 5250 data stream, or take a conceptually similar direction using RPG OA. Does this approach represent a modern architecture for web development? At CNX we answer that question with an emphatic “No!” With Valence you apply a modern Web 2.0 paradigm that operates on the same underlying design structure as top applications from Google, Facebook, Salesforce.com, etc. Advanced web applications like these use an asynchronous structure, calling the backend programs (in our case RPG) in chunks only when necessary, thereby optimizing application performance for the users. With Valence, multiple RPG programs can be running at once for the same user session, all performing simultaneous actions.
You can still program your business logic in RPG—there is no Voodoo!
Everything with Valence is understandable and in your control, and layers are minimized. When you’re running a Valence app in your browser, that app is communicating with your RPG programs directly through the built-in Apache server on IBM i. There are no external servers and no “emulation” layers. It’s just the browser with an advanced interface talking with RPG. Forget about the Voodoo—it doesn’t get more native than this! Some competitor products generate “junk” RPG output that you can’t maintain. With Valence you can utilize tools that generate clean, readable RPG output, or you can simply write it yourself. In either case you still have full access and control of all the code behind your programs.
