**mongodb-atomicapp** is an external Nulecule app[1], which defines
it's own set of params. The params for **mongodb-atomicapp** has no
knowledge and relation with params defined in **manticore-atomicapp**
component[2]. Since, some the param names in both the components:
mongodb-atomicapp, manticore-atomicapp are same, it seems like that
they are redundant, but actually, they are different.

On the other hand, this example does not have an external dependency
to another Nulecule application.

Currently, given the schema of answers file, and also due to the
Nulecule spec, there isn't a way to pass params and data from one
component to the other, or have proper inheritance of components. This
is a limitation and we are brainstorming on how to make things better.

I hope that this answers your question. Let us know if you have any doubt.
