Concepts of critical thinking, logical thinking, creative thinking and mind mapping can also be incorporated where appropriate. The real world is very complex and as such it is very difficult, if not impossible, to capture information accurately and comprehensively. 1 shows a network representation of information as objects interconnected together. This diagram may appear complex but is in really a simplistic representation of the real world. Hierarchical structures Information is often arranged in hierarchical structures to help us understand it better.
Hierarchical structures are one of the key foundations of the sciences and our knowledge systems.
It allows us to communicate at a higher order once we are familiar with the hierarchies. Hierarchical structures are represented in our classification systems for example the library systems and WTO tariff codes. Unfortunately hierarchies represent the human understanding of the world which may not necessarily be accurate. A single hierarchy can also be self limiting as information may belong to multiple hierarchies. Library systems have been based on hierarchical systems and I understand they have realised the limitations and are moving away from single hierarchical systems.
