"There are two types of knowledge: explicit and implicit. Explicit knowledge is held in data in physical and electronic form. To access it you need systems which can sort, search and sift the data. More recently this process has been improved so that the data turns more into information. For example, turning raw “likes” of a Facebook page (which is data) into trends and habits of individuals gives you something you can work with, i.e. information."
