This document refers to the following terms.
|Path||An ordered, start-to-finish series of actions, for example, page views, for which sequences and sub-sequences can be generated.|
|Sequence||A sequence is the path prefixed with a carat (^), which indicates the start of a path. For example, if a user visited page a, page b, and page c, in that order, the session sequence is ^,a,b,c.|
|Sub-sequence||For a given sequence of actions, a sub-sequence is one possible subset of the steps that begins with the initial action. For example, the path a,b,c generates three subsequences: ^,a; ^,a,b; and ^,a,b,c.|
