The third aim of bioinformatics is to analyze the biological data through the use of complex mechanisms and convert the data in such a form that is biologically meaningful. In traditional biological studies, examining individual systems and comparison with only a few related fields was possible. But Bioinformatics has allowed the global analysis and comparison of data available from a variety of fields. Clearly, developing methods to assess the differences between different varieties of biomolecules and identifying similarities over a wide range of dissimilar sources is an essential aspect of managing the huge volumes of data and thus of bioinformatics.
