Every day a new tool or framework appears on the market. Using a technology means to have a marriage with it, very often forever. What happens if you want to change the DBMS you're using or the engine that persist your objects? Or again your web framework?

Divorces, you know, are costly. Many technologies don't follow standards so the migration cost is huge. Often it's cheaper to rewrite it from scratch.

Roma is the only “meta” framework. Using Roma you're definitely free from the technology you're using. How it works? Roma provides very generic behaviour interfaces called “Aspects”. Aspects enclose the most common use cases. Using the tool and framework through the Aspect allow to leave your code clean from the technology.

Roma Aspects

But if I need to dirt my hands using the technology directly, can I do it with Roma? Sure. You can always reach the implementation under the hood. Just remember you had to migrate that pieces of code in case tomorrow you'll change the technology. In the documentation you can find some best practice to make migration the easiest possible.

Abstracting the technologies let you to have the development team aware of their. This can be translated as minor skill requested, therefore less cost.
