Best of 2024: Developing Redwood Applications
Description
Welcome to the Oracle University Podcast, the first stop on your cloud journey. During this series of informative podcasts, we’ll bring you foundational training on the most popular Oracle technologies. Let’s get started.
Nikita: Hello and welcome to the Oracle University Podcast! I’m Nikita Abraham, Team Lead: Editorial Services with Oracle University, and with me is Lois Houston, Director of Innovation Programs.
Lois: Hi everyone! Thanks for joining us for this Best of 2024 series, where we’re playing for you our four most popular episodes of the year.
Nikita: Today’s episode is #3 of 4 and is a throwback to another conversation with Joe Greenwald, our Senior Principal OCI Instructor. We asked Joe about Oracle’s Redwood design system and how it helps us create stunning, world-class enterprise applications and user experiences.
Lois: Yeah, Redwood is the basis for all the new Oracle Cloud Applications being re-designed, developed, and delivered. Joe is the best person to ask about all of this because he’s been working with our Oracle software development tools since the early 90s and is responsible for OU’s Visual Builder Studio and Redwood course content. So, let’s dive right in!
Joe: Hi Lois. Hi Niki. I am excited to join you on this episode because with the release of 24A Fusion applications, we are encouraging all our customers to adopt the new Redwood design system and components, and take advantage of the world-class look and feel of the new Redwood user experience.
Redwood represents a new approach and direction for us at Oracle, and we’re excited to have our customers benefit from it.
Nikita: Joe, you’ve been working with Oracle user interface development tools and frameworks for a long time. How and why is Redwood different?
Joe: I joined Oracle in 1992, and the first Oracle user interface I experienced was Oracle Forms. And that was the character mode. I came from a background of Smalltalk and its amazing, pioneering graphical user interface (GUI) design capabilities. I worked at Apple and I developed my own GUIs for a few years on PCs and Macs. So, Character Mode Forms, what we used to call DMV (Department of Motor Vehicles) screens, was a shock, to say the least. Since then, I’ve worked with almost every user interface and development platform Oracle has created: Character Mode Forms, GUI Forms, Power Objects, HyperCard on the Macintosh, that was pre-OS X by the way, Sedona, written in native C++ and ActiveX and OLE, which didn’t make it to a product but appeared in other things later, ADF Faces, which uses Java to generate HTML pages, and APEX, which uses PL/SQL to generate HTML pages. And I’ve worked with and wrote training classes for Java Swing, an excellent GUI framework for event-driven desktop and enterprise applications, but it wasn’t designed for the web.
So, it’s with pleasure that I introduce you to the Redwood design system, easily the best effort I’ve ever seen, from the look and feel of holistic user-goal-centered design philosophy and approach to the cutting-edge WYSIWYG design tools.
Lois: Joe, is Redwood just another set of styles, colors, and fonts, albeit very nice-looking ones?
Joe: The Redwood platform is new for Oracle, and it represents a significant change, not just in the look and feel, colors, fonts, and styles, I mean that too, but it’s also a fundamental change in how Oracle is creating, designing, and imagining user interfaces.
As you may be aware, all Oracle Cloud Applications are being re-designed, re-engineered, and re-rebuilt from the ground up, with significant changes to both back-end and front-end architectures. The front end is being redesigned, re-developed, and re-created in pure HTML5, CSS3, and JavaScript using Visual Builder Studio and its design-time browser-based Integrated Development Environment. The back end is being re-architected, re-designed, and implemented in a modern microservice architecture for Oracle Cloud using Kubernetes and other modern technologies that improve performance and work better in the cloud than our current legacy architecture.
The new Oracle Cloud Applications platform uses Redwood for its design system—its tools, its patterns, its components, and page templates. Redwood is a richer and more productive platform to create solutions while still being cost-effective for Oracle. It encourages a transformation of the fundamental user experience, emphasizing identifying, meeting, and understanding end users’ goals and how the applications are used.
Nikita: Joe, do you think Oracle's user interface has been improved with Redwood? In what ways has the UI changed?
Joe: Yes, absolutely. Redwood has changed a lot of things. When I joined Oracle back in the '90s, there was effectively no user interface division or UI team. Everybody just did their own thing. There was no user interface lab—and that was started in the mid-‘90s—and I was asked to give product usability feedback and participate in UI tests and experiments in those labs. I also helped test the products I was teaching at the time.
I actually distinctly remember having to take a week to train users on Oracle’s Designer CASE tool product just to prep the participants enough to perform usability testing. I can still hear the UI lab manager shaking her head and saying any product that requires a week of training to do usability testing has usability issues! And if you’re like me and you’ve been around Oracle long enough, you know that Oracle’s not always been known for its user interfaces and been known to release products that look like they were designed by two or more different companies. All that has changed with Redwood.
With Redwood, there’s a new internal design group that oversees the design choices of all development teams that develop products. This includes a design system review and an ongoing audit process to ensure that all the products being released, whether Fusion apps or something else, all look and feel similar so it looks like it’s designed by a single company with a single thought in mind. Which it is.
There’s a deeper, consistent commitment in identifying user needs, understanding how the applications are being used, and how they meet those user needs through things like telemetry: gathering metrics from the actual components and the Redwood system itself to see how the applications are being used, what’s working well, and what isn’t.
This telemetry is available to us here at Oracle, and we use it to fine tune the applications’ usability and purpose.
Lois: That’s really interesting, Joe. So, it’s a fundamental change in the way we’re doing things. What about the GUI components themselves? Are these more sophisticated than simple GUI components like buttons and text fields?
Joe: The graphical components themselves are at a much higher level, more comprehensive, and work better together. And in Redwood, everything is a component. And I’m not just talking about things like input text fields and buttons, though it applies to these more fine-grained components as well. Leveraging Oracle’s deep experience in building enterprise applications, we’ve incorporated that knowledge into creating page templates so that the structure and look and feel of the page is fixed based on our internal design standards. The developer has control over certain portions of it, but the overall look and feel of the page is controlled by Oracle. So there is consistency of look and feel within and across applications.
These page templates come with predefined functionalities: headers, titles, properties, and variables to manipulate content and settings, slots for other components to hold like search fields, collections, contextual information, badges, and images, as well as primary and secondary actio
