I have an idea for an application  where users submit json files that represent different data that needs to be parsed and put in a DB. I believe there may be many many different types of this input data over time so I had this idea that I would break down the different models by applications. 

This would allow me to keep different types of data separated and displayed differently. 

My question is this: 

Is this a good idea?

if I break things up into different applications can I also create a federated search across apps?

Thanks
