Information architecture (IA) is the structural design of shared information environments; the art and science of organizing and labeling websites, intranets, online communities, and software to support usability and findability; and an emerging community of practice focused on bringing principles of design, architecture and information science to the digital landscape. Typically, it involves a model or concept of information that is used and applied to activities that require explicit details of complex information systems. These activities include library systems and database development.
Information management lies between data management and knowledge management. Data management focuses on handling individual pieces of data for example by using databases. Knowledge management focuses on information that exists within a human’s mind, and how to extract and share this. Information Architecture is distinct from process management but there are often valuable interactions between information and process and practitioners have developed tools such as information/process matrices.
