The concept of architecture has been widely used in the context of information and communication technologies (ICT's). It is associated with such diverse terms, such as, business architecture, architecture of knowledge, strategic architecture, governance architecture, information architecture, architecture of competence, ICT's architecture, network architecture, computer architecture, data architecture, and many other examples one could give. Why the term is used in this way? What sets them apart? May it be replaced by a simpler and less catchy term, such as structure? Information architecture is a design methodology (concept) that is applied to any environments, being understood as an area located within a given context, consisting of content in streams that serves a community of managers/decision makers/users. The model can be to any informational environments of any area of knowledge, regardless of media, format, content or type of information that constitutes it, since a traditional library to a complex organization. It is not coupled to people, to the organizational structure or any technology.
