ABSTRACT
Collected data constitute a basic source of information. They form a window that we use to look at our environment (Singh et al., 2003). Data are used for a large number of activities (see Chapters 1 and 3), such as for assessment of a system’s performance, calibration and verification of Integrated Urban Water Management (IUWM) models, real-time control of IUWM systems. The portability, presence of metadata, and their reliability are critical to the process of data translation into required knowledge. The steps and procedures used for turning data into information, and then finally into knowledge are explained in this chapter.
