The evolution of the database concept to include opinions and other forms of non-factual information. Databases are commonly used to store empirical imformation i.e. facts, figures, interviews. A metabase would store not only these but opinions, personal articles, imaginings, emotions, and other non-empirical, non-verifiable information. This is in line with modern thoughts concerning the subjectivity of reality, and the impossibility of objective information. Meaning that, effectively, all databases are in fact metabases. Using these parameters, it could be said that Everything is a metabase, and a particulary fine example of one.
