@eparejatobes The idea behind integrating biological data sources is that whatever data that resides at different sources manily talking about protiens and genes should be brought together at one place so as to easy retrival of data for everyone. Later I have planned to view it as a website through which one may fetch the information required by giving one input. In short my idea to interlink the related data of proteins / genes (any one of them) and retrive it using the simple queries and getting the idea of intergrating the databases. Apologize, if I am unable to explain you properly. I have only little knowledge about it and want to explore more in this field.
