I am trying to integrate the databases for 5 websites into my site and allow my users to search through them and see the results side-by-side so they can compare them.
I've made a blue print of what I am trying to do:
Now these 5 sites have APIs and data-feed programs but I am not a part of them (nor can I be).
Is it possible to integrate or access the databases of these 5 sites without being an affiliate and having access to their affiliate/API/data resources.
I had a programmer who claimed he could do it but then told me he couldn't.
Is this impossible or simply difficult?
I would appreciate some answers and advice.
