Nowadays, data needed to be stored, scaled and analyzed is increasing rapidly in more and more research areas like biology, sociology, telecommunication, etc. Because of the limited information about them, their understanding was made difficult and, as a result, advancing in many fields faced with such complex systems was hindered. Using data analysis systems like networks makes all these issues have a smooth solution. The results obtained in trying to perceive such complex metters by using this technique is admirable. More and more research areas like the ones named before have known beautiful progress in understanding the complex way they operate.
