SPRINGERBRIEFS IN COMPUTER SCIENCE DATA INFOR...

This SpringerBrief presents the data- information-and-time (DIT) model that precisely clarifies
the semantics behind the terms data  information and their relations to the passage of real
time. According to the DIT model a data item is a symbol that appears as a pattern (e.g. 
visual  sound  gesture  or any bit pattern) in physical space. It is generated by a human or a
machine in the current contextual situation and is linked to a concept in the human mind or a
set of operations of a machine. An information item delivers the sense or the idea that a human
mind extracts out of a given natural language proposition that contains meaningful data items.
Since the given tangible  intangible and temporal context are part of the explanation of a data
item  a change of context can have an effect on the meaning of data and the sense of a
proposition. The DIT model provides a framework to show how the flow of time can change the
truth-value of a proposition. This book compares our notions of data  information  and time in
differing contexts: in human communication  in the operation of a computer system and in a
biological system. In the final Section a few simple examples demonstrate how the lessons
learned from the DIT-model can help to improve the design of a computer system.
