In recent years, there has been considerable growth of different kind of networks. From physics and computer science to biology and the social sciences, researches have found that a great variety of systems can be represented as networks. Network evolution has led to the extensive investigations in order to understand and explain network effects. The main advantage is that graph theoretic concepts can be used as principal mathematical language for describing properties of networks. One of the continuously and rapidly evolving fields in the study of networks and complex systems is structural reasoning based on Social Network Analysis (SNA). The purpose of the paper is to discuss about the importance and possibilities of structural reasoning based on SNA and to show the application of SNA for non-typical social network. In this article particular interest is devoted to the relational analysis of network.
