OutSystems ODC vs O11? Not anymore!

Now that we’ve gotten all the ODC vs O11 stuff out of the way, here are 5 things I think are important to know if you have OutSystems 11 experience and you want to try ODC.

1. Application architecture design: ODC vs O11

While this is not part of the development process, the decisions you make during the application architecture design will have an impact on the development experience. In OutSystems 11, we use the Disclose, Organize and Assemble process to design the architecture of an application. In ODC, the focus of this process shifts to understanding the organizational context of the application.

Disclose

Understand the stakeholder’s needs and the business owners/sponsors structure in the organization. This will come in handy for the organize step.

Organize

With the needs and organizational structure disclosed we now need to identify the bounded contexts. In the end we group the business concepts by bounded context.

Assemble

Finally we assemble our applications given the bounded context from the previous step and ensure team autonomy and clear ownership of the applications.

2. Where are my modules? Not a thing in ODC

If you’re an experienced OutSystems 11 developer, the lack of modules might mess with your head a bit. But, trust me, when you get used to it, you’ll see the development speed increase significantly. Why? Because we got used to arranging our code into pretty neat little boxes called modules: database here, business logic there, and UI over there. The downside of this is having to create code (actions and blocks) to wrap the application’s features in each of these boxes to be used by the other boxes. Hey, how many CRUD wrappers can we create, amirite? What about those blocks that use other blocks using other blocks?

When you get used to structuring code at the app level in ODC, you will see the amount of “unnecessary” code you’ve been creating in the past years. You now have everything in one place, the application.

3. Sharing data between apps and other patterns

If you are building just one app, this won’t matter. But let’s say that you are consuming a REST API or you have a web and mobile app. How do you share and change data that is consumed by both apps? And how do you consume a REST API now? What about themes?

In the O11 world, you create an App, which can be web, tablet, or mobile. But in ODC, you can build not only an App but also a Library. An App is what you are used to in OutSystems 11. A Library is where you create business-agnostic code to be reused by another application. Libraries are deployed together (meaning, same container) with the application that is consuming it. This Library is one reason why some developers chose ODC back when OutSystems 11 vs ODC was a thing.

Once again, we got you covered with one more ODC training course–architecture patterns in ODC.

4. Let me tell you a secret

How many times have you wished you could have a Site Property (now, also known as Setting) as an API Key that could be used by different applications with a different value? Or just have its value hidden like a password?

Well, let me tell you a secret… You can now!

It’s called a Secret Setting.

5. SQL Server is dead, long live Aurora PostgreSQL!

While this will not change your daily experience it might come in handy to know the underlying database technology in ODC. I’m sharing this in case you need to get jiggy with your data in development.

Here’s a helpful guide for your adventures: SQL queries in ODC vs OutSystems 11.

There’s a lot more to talk about ODC, but I wouldn’t ruin all the fun of experiencing it firsthand by telling you every little detail! And remember, you can now try ODC while still using O11. The lines drawn in the sand during the OutSystems ODC vs O11 standoff have washed away. And the O11 to ODC migration? A thing of the past.
