Integration of various technologies

Hi,

Till now I worked on Enterprise Portals, BSP and some part of XI. But I havent worked on integration of all these technologies. I heard that a NetWeaver consultant is supposed to integrate various technologies.

I know the purpose of integration but I would like to know what to integrate, how to integrate. Can any body plz suggest me on this?? It would be more better if any one could provide me some material.....

Thanks,

Satish.
