Interactions are investigated between Boolean inquiry statements and distributions of attributes in data bases. Boolean inquiry statements are composed of simple conjunctions and disjunctions of multiple and single search keys. The attributes are distributed with either the uniform probability law or Zipf's law. Random variables are introduced and their event (search) space is defined. Expectations and variances are specified. This analysis suggests a method for the development of a technique that can be used in further research for the study of interactions betwen queries and attributes in data bases.
