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!
00:47
Lois: Hello and welcome to the Oracle University Podcast. I’m Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Principal 
Technical Editor. 
Nikita: Hi everyone! Last week, we went through the basics of artificial intelligence and we’re going to take it a step further today by talking about some foundational machine learning concepts. After that, we’ll discuss the three main types of machine learning models: supervised learning, unsupervised learning, and reinforcement learning. 
01:18
Lois: Hemant Gahankari, a Senior Principal OCI Instructor, joins us for this episode. Hi Hemant! Let’s dive right in. What is machine learning? How does it work?
Hemant: Machine learning is a subset of artificial intelligence that focuses on creating computer systems that can learn and predict outcomes from given examples without being explicitly programmed. It is powered by algorithms that incorporate intelligence into machines by automatically learning from a set of examples usually provided as data. 
01:54
Nikita: Give us a few examples of machine learning… so we can see what it can do for us.
Hemant: Machine learning is used by all of us in our day-to-day life. 
When we shop online, we get product recommendations based on our preferences and our shopping history. This is powered by machine learning. 
We are notified about movies recommendations based on our viewing history and choices of other similar viewers. This too is driven by machine learning. 
While browsing emails, we are warned of a spam mail because machine learning classifies whether the mail is spam or not based on its content. In the increasingly popular self-driving cars, machine learning is responsible for taking the car to its destination. 
02:45
Lois: So, how does machine learning actually work?
Hemant: Let us say we have a computer and we need to teach the computer to differentiate between a cat and a dog. We do this by describing features of a cat or a dog. 
Dogs and cats have distinguishing features. For example, the body color, texture, eye color are some of the defining features which can be used to differentiate a cat from a dog. These are collectively called as input data. 
We also provide a corresponding output, which is called as a label, which can be a dog or a cat in this case. By describing a specific set of features, we can say that it is a cat or a dog. 
Machine learning model is first trained with the data set. Training data set consists of a set of featur

You probably interact with artificial intelligence (AI) more than you realize. So, there’s never been a better time to start figuring out how it all works.
 
Join Lois Houston and Nikita Abraham as they decode the fundamentals of AI so that anyone, irrespective of their technical background, can leverage the benefits of AI and tap into its infinite potential.
 
Together with Senior Cloud Engineer Nick Commisso, they take you through key AI concepts, common AI tasks and domains, and the primary differences between AI, machine learning, and deep learning.

00:46
Nikita: Hello and welcome to the Oracle University Podcast. I’m Nikita Abraham, Principal Technical Editor with Oracle University, and with me is Lois Houston, Director of Innovation Programs.
Lois: Hi there! Welcome to a new season of the Oracle University Podcast. I’m so excited about this season because we’re going to delve into the world of artificial intelligence. In upcoming episodes, we’ll talk about the fundamentals of artificial intelligence and machine learning. And we’ll discuss neural network architectures, generative AI and large language models, the OCI AI stack, and OCI AI services.
01:27
Nikita: So, if you’re an IT professional who wants to start learning about AI and ML or even if you’re a student who is familiar with OCI or similar cloud services, but have no prior exposure to this field, you’ll want to tune in to these episodes.
Lois: That’s right, Niki. So, let’s get started. Today, we’ll talk about the basics of artificial intelligence with Senior Cloud Engineer Nick Commisso. Hi Nick! Thanks for joining us today. So, let’s start right at the beginning. What is artificial intelligence?
01:57
Nick: Well, the ability of machines to imitate the cognitive abilities and problem solving capabilities of human intelligence can be classified as artificial intelligence or AI. 
02:08
Nikita: Now, when you say capabilities and abilities, what are you referring to?
Nick: Human intelligence is the intellectual capability of humans that allows us to learn new skills through observation and mental digestion, to think through and understand abstract concepts and apply reasoning, to communicate using a language and understand the nonverbal cues, such as facial recognition, tone variation, and body language. 
You can handle objections in real time, even in a complex setting. You can plan for short and long-term situations or projects. And, of course, you can create music and art or invent something new like an original idea. 
If you can replicate any of these human capabilities in machines, this is artificial general intelligence or AGI. So in other words, AGI can mimic human sensory and motor skills, performance, learning, and intelligence, and use these abilities to carry out complicated tasks without human intervention. 
When we app

Visual Builder Studio requires its data sources to connect to the webpage it produces using REST calls. Therefore, the data source has to provide a REST interface. A simple, easy, secure, and free way to do that is with Oracle REST Data Services (ORDS).
 
In this episode, hosts Lois Houston and Nikita Abraham chat with Senior Principal OCI Instructor Joe Greenwald about what ORDS can do, how to easily set it up, how to work with it, and how to use it within Visual Builder Studio.

Nikita: Hello and welcome to the Oracle University Podcast! I’m Nikita Abraham, Principal Technical Editor with Oracle University, and with me is Lois Houston, Director of Innovation Programs.
 
Lois: Hi there! In our last episode, we took a look at model-based development tools, their start as CASE tools, what they morphed into, and how they’re currently used in Oracle software development. We’re wrapping up the season with this episode today, which will be about how to access Oracle database data through a REST interface created and managed by Oracle REST Data Services, or ORDS, and how to access this data in Visual Builder Studio.
 
01:03
Nikita: Being able to access Oracle database data through a REST interface over the web is highly useful, but sometimes it can be complicated to create that interface in a programming language. Joe Greenwald, our Senior OCI Learning Solutions Architect and Principal Instructor is back with us one last time this season to tell us more about ORDS, and how it makes it much simpler and easier for us to REST-enable our database for use in tools like Visual Builder Studio. Hi Joe! Tell us a little about what Visual Builder Studio is and why we must REST-enable our data for VBS to be able to use it.
 
01:40
Joe: Hi Niki, hi Lois! Ok, so, Visual Builder Studio is Oracle’s low-code software development and project asset management product for creating graphical webpage front-ends for web applications. It’s the tool of choice for designing, building, and implementing all of Oracle Fusion Cloud Applications and is being used by literally tens of thousands of engineers at Oracle now to bring the next generation of Fusion Applications to our customers and the market.
It’s based on standards like HTML5, CSS3, and JavaScript. It’s highly performant and combined with the Redwood graphical design system and components that we talked about previously, delivers a world-class experience for users.
One thing about Visual Builder Studio though: it only works with data sources that have a REST interface. This is unusual. I like to think I’ve worked with every software development tool that Oracle’s created since I joined Oracle in 1992, including some unreleased ones, and all of them allowed you to talk to the database directly. This is the first time that we’ve released a tool that I know of where we don’t do that.
Now at first, I was a little put off and wondered how’s it going to do this and how much work I would have to

Computer Aided Software Engineering (CASE) tools, which helped make the analysis, design, and implementation phases of software development better, faster, and cheaper, fell out of favor in the mid-'90s. Yet much of what they have to offer remains and is in active use within different Oracle tools.
 
Listen to Lois Houston and Nikita Abraham interview Senior Principal OCI Instructor Joe Greenwald about the origins of CASE tools and model-based development, as well as how they evolved into their current forms.

Nikita: Hello and welcome to the Oracle University Podcast! I’m Nikita Abraham, Principal Technical Editor with Oracle University, and joining me is Lois Houston, Director of Innovation Programs.
 
Lois: Hi there! In our last episode, we looked at Oracle’s Redwood design system and how it helps create world-class apps and user experiences. Today, Joe Greenwald, our Senior Principal OCI Instructor, is back on our podcast. We’re going to focus on where model-based development tools came from: their start as CASE tools, how they morphed into today’s model-based development tools, and how these tools are currently used in Oracle software development to make developers’ lives better.
 
01:08
Nikita: That’s right. It’s funny how things that fell out of favor years ago come back and are used to support our app development efforts today. Hi Joe!
 
Joe: Haha! Hi Niki. Hi Lois.

01:18
Lois: Joe, how did you get started with CASE tools? 
 
Joe: I was first introduced to computer-aided software engineering tools, called CASE tools, in the late 1980s when I began working with them at Arthur Young consulting and then Knowledgeware corporation in Atlanta, helping customers improve and even automate their software development efforts using structured analysis and design techniques, which were popular and in high use at that time. But it was a pain to have to draw diagrams by hand, redraw them as specifications changed, and then try to maintain them to represent the changes in understanding what we were getting from our analysis and design phase work. CASE tools were used to help us draw the pictures as well as enforce rules and provide a repository so we could share what we were creating with other developers.
I was immediately attracted to the idea of using diagrams and graphical images to represent requirements for computer systems. 
02:08
Lois: Yeah, you’re like me. You’re a visual person.
Joe: Yes, exactly. So, the idea that I could draw a picture and a computer could turn that into executable code was fascinating to me. Pictures helped us understand what the analysts told us the users wanted, and helped us communicate amongst the teams, and they also helped us validate our understanding with our users. This was a critical aspect because there was a fundamental cognitive disconnect between what the users told the analysts they needed, what the analysts told us the users needed, and what we understood was needed, and

Redwood is a state-of-the-art graphical interface that defines the look and feel of the new Oracle Cloud Redwood Applications. 
In this episode, hosts Lois Houston and Nikita Abraham, along with Senior Principal OCI Instructor Joe Greenwald, take a closer look at the intent behind the design and development aspects of the new Redwood experience. They also explore Redwood page templates and components.

Lois: Hello and welcome to the Oracle University Podcast! I’m Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Principal Technical Editor.
Nikita: Hi everyone! Last week, we discussed how Visual Builder Studio can be used to extend Oracle Fusion Apps. 
Lois: That’s right, Niki. In today’s episode, we will focus on Oracle’s Redwood design system and how it helps us create stunning, world-class enterprise applications and user experiences. 
00:56
Nikita: Yeah, Redwood is the basis for all the new Oracle Cloud Applications being re-designed, developed, and delivered. To tell us more, we have Senior OCI Learning Solutions Architect and Principal Instructor Joe Greenwald, who’s been working with Oracle software development tools since the early 90s and is responsible for OU’s Visual Builder Studio and Redwood course content.
Lois: Hi Joe! Thanks for being with us today.
01:21
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.
01:44
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

What do you need to start customizing the next generation of Oracle Fusion Apps? How do you create new pages for business processes? What level of expertise do you require for this?

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.
00:26
Lois: Hello and welcome to the Oracle University Podcast! I’m Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Principal Technical Editor.
Nikita: Hi everyone! Last week, we were introduced to Visual Builder Studio and the Oracle JavaScript Extension Toolkit, also known as JET.
Lois: Our friend and Senior Principal OCI Instructor Joe Greenwald is back with us today to talk about how to extend Oracle Cloud Applications that are being built using Visual Builder for its front-end.
Nikita: That’s right. All Fusion Applications are being redesigned and rebuilt using Visual Builder. And we’ll find out more about that from Joe. Hi Joe! Thanks for being with us today.
Joe: Hi Lois! Hi Niki! My pleasure to be here.
01:09
Nikita: Joe, tell us a little about what’s happening with the redesign and re-architecture of Oracle Cloud Applications using Visual Builder Studio, or VBS. I hear some very exciting changes are coming that are important for our customers and partners.
Joe: That’s right, Niki. Oracle is redesigning and rebuilding its entire suite of Fusion Cloud Applications, over 330 different products, utilizing over 60,000 engineers — that is “60,” not “16” — at Oracle to develop the next generation of Oracle Fusion Applications. What’s most exciting is that the same tools the engineers are using to accomplish this are available to our partners and our customers to use to extend the functionality and capabilities of Fusion Applications to meet their custom needs and processes. 
01:54
Lois: That’s pretty awesome! We want to use this time today to ask you about extensions, the types of extensions you can create, and how to use Visual Builder Studio to create those extensions.
Nikita: Yeah, can we start with you telling us what an extension is? I’ve gotten the sense that Oracle uses the term extension as both a noun and a verb and that’s a bit confusing to me.
02:15
Joe: Yeah, good catch, Niki. Yes, Oracle does use the term extension in two ways: both as a noun and a verb. As a noun, an extension is a container for the code changes that you make to your applications. Basically, it’s a Git repository that Oracle creates and manages for you. So, the extension container holds the code changes you make to your page layouts: the fields, their positioning, showing and hiding fields, that sort of thing, as well as page functionality. These code changes you make are stored in the extension and it is this extension with your code changes that is merged with the main Git branch eventually and then deployed using continuous integration/continuous deployment jobs defined in Visual Builder Studio
