Takeaways from OOW'17

Let's summarise important points from OOW'17 conference. This year conference was a breakthrough for Oracle JET - most of Oracle Cloud UI's were implemented with Oracle JET. Oracle ADF is used for Oracle SaaS (Fusion Middleware) back office applications, same as before. There is often misunderstanding in JET vs. ADF comparison. Keep in mind - JET is only UI layer and it can be compared with ADF Faces only. While ADF is much more than UI - ADF BC Model, ADF Task Flows and ADF Bindings.

1. Use JET for front-end apps, with relatively simple complexity but strong requirement for performance and scalability. Back-end can be implemented with ADF BC REST. Typically it would take longer to implement JET UI comparing to ADF Faces (no drag and drop support, unless using Visual Cloud Builder Service for JET)

2. Use ADF Faces for complex and large back-office applications. Some degree of mix between ADF Faces and JET is possible. Back-end should be done in ADF BC

ADF is stable technology and Oracle is focusing to advertise new things on OOW. Recommended focus for ADF developers was around JCS, DevCS, JET and VBCS:

There was one session about how to move existing ADF app into the cloud with JCS. And session about ADF BC REST, no new features - mainly showing customer system implementation with current features.

JET open source contribution was announced, along with new JET offline support - persistence toolkit (will be available through NPM in next couple of weeks):

Oracle explained why handling offline use case in JET is important:

Persistence toolkit will run on JET hybrid, web and desktop apps (yes you can run JET as desktop app, with 3-rd party Electron plugin):

Here you can read more detail info about persistent toolkit design principles:

JET supports Fetch API (used by persistence toolkit):

Architecture explanation for JET persistence toolkit:

Another hot topic related to JET - Web components. Slots are supported, this allows to build advanced Web components with dedicated facets (ADF Faces terminology):

OOW'17 was packed with chatbot demos. Unfortunately there is no trial access for chatbot cloud yet. There was good session about chatbots from Lyudmil Pelov - he explained how Oracle chatbot service and language processing works:

I was impressed with Oracle Visual Cloud Builder Service progress this year. I really liked this service and I think it will become JET IDE development tool. Is not focused for business users only, but is targeted for JET developers too. It comes with embedded DB or you can call external services too. Next versions will allow direct JET code development, combined with drag and drop:

Develop JET in VBCS using drag and drop where possible and code additional logic in JS/HTML:

VBCS is not targeted for business users anymore, they target it for coders (us) too - thats news I like:

RDK UI is available now for ADF, JET and MAF. ADF RDK was updated to newer version. ADF and JET RDK UI look is identical.

New ADF RDK UI:

JET RDK UI:

Machine Learning was another big thing on OOW and JavaOne. Nice to hear things I was studying in university about neural networks are becoming hype now:

JVM garbage collection tuning. Is better to have objects to be dead young. This means in ADF is better to use Backing Bean Scope where possible, because short scope bean is destroyed after request and this allows VM to clean memory:

OOW'15 Session Slides - Oracle Alta UI Patterns for Enterprise Applications and Responsive UI Support

You can view slides from recent OOW'15 session (Oracle Alta UI Patterns for Enterprise Applications and Responsive UI Support [UGF2717]) on SlideShare:

I was explaining how to implement responsive layout and fast performance ADF 12c applications with Alta UI. New ADF 12.2.1 features were discussed. Session went pretty well, all demos were working without issues. I was happy with the feedback, for example a tweet from Grant Ronald:

Here you can download session demo application - oow15.zip. This application includes high performance ADF Alta UI dashboard with WebSockets.

OOW'15 Session Preview - Oracle Alta UI Patterns for Enterprise Applications and Responsive UI Support

This is preview post for my OOW'15 session - Oracle Alta UI Patterns for Enterprise Applications and Responsive UI Support [UGF2717]. I'm going to talk and demo various useful things about Alta UI and ADF. Title talks about UI, but there will be much more. I'm going to show you, Alta UI is not only about look and feel, it is totally new way of building enterprise applications. Certainly UI is very important, but you should not forget about such topics as performance, scalability and reusability. All this and modern UI would make your enterprise application successful.

One of the key topics I will be speaking about - high performance data integration into Alta UI. I will be using live data from Twitter and through WebSocket channel communicating it to Alta UI ADF 12c dashboard screen. I have recorded preview video, you can watch it here:

Dashboard UI with live Twitter data is based on my previous example - Dashboard Implementation with ADF 12c Alta UI. Twitter stream data is managed in ADF 12c application by JavaScript function, here I'm receiving message from WebSocket, parsing it with JSON and assigning values to to ADF UI components:

This is the result displayed in Alta UI:

I will cover these topics during session:

1. High performance dashboard implementation for Alta UI

2. Responsive UI support

3. ADF Regions usage and responsive UI

4. List component usage

5. Menu and Panel Drawer

6. Editable forms implementation in Alta UI

7. Dynamic editable forms implementation

8. Master-Detail implementation in Alta UI

9. Table pagination implementation

10. ADF BC auto-refresh functionality

11. Coexistence of Alta UI and previous ADF skins

See you soon in San Francisco !

ADF Project Development Time Distribution

Here you can see a video from my OOW'12 session, where I'm describing how development time splits for ADF projects. This should give you good idea for planning and estimating ADF project development time:

One of the key things - ADF BC development time always takes less comparing to ADF UI development time. This is not obvious when you are about to start your first ADF project, but is always good to know in advance for proper planning:

Why Oracle ADF Developers are Sensitive People

Here you can hear a story I told during my OOW session (OOW'12: Oracle ADF Implementations Around the Globe: Best Practices). This is a true (may be a bit funny, if not sad :) story about ADF developer life and his fight with the deadline for ADF form implementation:

Enjoy and stay calm, even if the deadline is coming to you :)

OOW'12: Oracle ADF Implementations Around the Globe: Best Practices

Publishing slides for my OOW'12 session - Oracle ADF Implementations Around the Globe: Best Practices. I really did enjoy presenting this session - was fun to talk about ADF and see so many happy ADF users in the room :)

You can download slides for this session from here:

This session was based on different projects around the globe (total 4 continents):

I presented similarities and differences in ADF projects based on geographical locations:

Red Samurai performance audit tool was presented along with the demo (read more here):

Typical time distribution in ADF projects across technology stack was shown:

From our experience - ADF BC development takes less time and usually is the most smooth development phase in ADF. UI implementation is the most complex one.

If we take a look into ADF Model - ADF BC implementation and check time distribution. Usually it takes longer to implement View Objects (SQL, custom Java), also Application Modules (custom Java). Entity Objects implementation takes less time - because often is implemented as part of common reusable library:

Often people forget about generic classes and common code, its why I included it into this graph with 0% (to indicate its presence, is 0% because is implemented only once).

Similar graph with time distribution was presented for ADF ViewController. As expected, ADF UI implementation is the most complex and it takes longer:

I have presented how to speed up ADF development with completely dynamic forms, generated on runtime (generated: ADF BC (EO, VO, LOV) and ADF UI). I will post sample application for this in my future posts. Now I'm posting architecture diagram:

OOW'12: Oracle Business Process Management/Oracle ADF Integration Best Practices

I'm posting slides from our OOW'12 session - Oracle Business Process Management/Oracle ADF Integration Best Practices.
