Chapter 9.2: Analyzing Repetitive Data

































               Fig. 9.2.4 The difference between log tape data and repetitive data.


           In Fig. 9.2.4, repetitive data do not look like log data at all. It appears that in log data,
           many different kinds of records appear. And indeed, they do. But this apparent
           contradiction can be resolved by understanding that LOGICALLY, the log tape is
           nothing more than an amalgamation of repetitive records. This phenomenon is shown by
           Fig. 9.2.5.
