They can be embedded into clothes or into tools of our daily life. Progress in wireless communication technology leads to a "network of everything" [Mat01] and to an information exchange between these. Closely related to these technologies are new developments in the database and information systems area.. Information will be ubiquitous: Relevant information must be made available to anybody anytime and everywhere, depending on the context.enText/Conference Paper1617-5468
