Definition 8

(v). A value v (“v V”) is an element representing information about c, with V being empty, atomic, or multivalued. Thus, we define “V {v, , v}”, where v is the i-th value about c, and w is the number of values v in the set V.

For instance, mSaaS presented in Fig. 6(a) is the mapping of queries presented in Fig. 6(b); while mSaaS presented in Fig. 7(a) is the mapping of queries presented in Fig. 7(b).
