What is Arrow Notation

Chapter 46
Encyclopedia of Business Analytics and Optimization
Is an approach to data access where fields are used to navigate through a structure. The main difference from dot notation is that arrow notation is a set-oriented approach and arrow operators are applied to and return sets of elements rather than individual elements. Another difference from dot notation is that arrow notation uses two opposite operators for navigating in both directions. In COQL, arrows denote projection and de-projection operators.
